Brake Juddering Causes-What is it?

Home » All Car Servicing » Brake Servicing Halifax

Brake Juddering Causes

Foot pedal vibrations lead to the brake juddering experience

So, one of the first signs of brake juddering problems. Firstly, is when you can feel a vibration coming through your foot pedal. Secondly, when you press the clutch pedal. So, to brake and stop your car. Some of our customers say that it was a long drawn out process. Eventually though the brake began to get worse. Including the vibrations starting to come through the steering wheel.

Unfortunately, some of our customers think that the vibration is a wheel balancing problem! We also have to check out the problem with a correct diagnosis. However a braking problem will usually come through the brake pedal. So then this is a sure sign of a brake problem.

Unfortunately, one of the main Brake Juddering Causes come from elderly drivers. Significantly, who always cover the brake pedal with their right foot. This applies to manual gear changes or automatic, they what I call “ride the brake” some drivers also do this with the clutch but that’s a different article to cover. What happens if you ride the brake? Well one of the problems is that you are applying extra pressure onto the brake pads that are constantly in contact with the brake discs (brake rotors in the USA). These in turn over heat the discs, and the discs then warp and go out of shape.

Brake juddering is a bigger problem in hilly areas

In my opinion though, driver fault is not the main reason for warped brake discs. I think that the main cause is the terrain. We here in Halifax are in a hilly area and we get a high occurrence of warped brake discs and brake juddering faults from our customers.

In areas where there is very steep inclines, then drivers are more likely to keep their foot on the brakes. Some of the hills in the Hebden Bridge area are like alpine passes with 180 degree bends to contend with. When you come down these roads you have to keep the car in a low gear and be prepared for a vehicle coming up the hill, without braking all the time.

This constant braking is what overheats the discs and causes them to warp and vibrate giving Brake Juddering through your brake pedal. Some garages have a machine that will skim the brakes and stop the vibrating, but I think that once they have overheating then they do not work to their full potential and there for a new set of pads and discs is the best option.

Improved brake technology

Over the years car manufacturers have brought in new technology to balance out the disc overheating problem and try to eliminate the Brake Juddering Causes. Including different metals that can stand more heat and also the disc parts

that now come out with holes drilled in the metal at calculated intervals, for heat dispersal. This can work very well; you can see brake discs actually glowing red hot on some motor sport cars when they have to brake very often at high speed, some can be seen to be glowing white hot in the dark.

This has the same effect as the regular car driven by a regular driver. So, try to avoid heavy braking especially at high speed.  Keep your distance and try not to brake heavily. When you are driving down a steep hill, use a low gear and use the car’s engine as a brake, try not to press the brake pedal constantly.

Have your brakes inspected at regular intervals when the car is serviced. Of course, any worn discs or pads will be picked up by the garage. Importantly, we can even spot a disc that has been overheated in the past.  Because the disc has a blue coloured sheen on it. Remember like many other things to do with a car, prevention is better than a cure.

CAR BRAKES-New Ruling from EU coming soon? AEB (Autonomous Emergency Braking)

Home » All Car Servicing » Brake Servicing Halifax

car brakes to be updated for improved road safety

This is one of those articles that can be difficult to write. Of course, due to complex and differing points of view. Firstly the ruling although not compulsory is aimed at the car manufacturers. So, to update their cars by the end of this year (2014).

My problem is that now I am getting on a bit! I am realizing that my concentration is getting a few seconds slower than when I was a younger man. A couple of years  ago I did a battery delivery to East Yorkshire. On a nice sunny clear day. Because of my passion for cars I am always looking out when I pass a garage or a parking lot. Just in case I see a vintage or classic car.  So that I can photograph it for my blog.

On this particular occasion I glanced away from the road as I passed an old Land Rover parked in a field. I was driving at about 40 mph and turned to look back at the road in front. To my horror the traffic had stopped ahead of me and I had to slam on the car brakes ! Of course, as hard as I could. Missing the car in front by a whisker. I was really shaken and further on I had to pull into a pub car park. Thus, to re-compose myself and thought of what could have been.

This incident and the fact that there are millions of other drivers

So, in the same position as me. Prompted me to reflect on the snippets that I had been reading about a new system that would be introduced in 2014. It was in the think tank stages of the Eu New Car Assessment Programme then or (Euro NCAP).

The system known as AEB (Autonomous Emergency Braking) will be expected to be fitted to new cars. Hence, by the end of this year (2014). The new technology will become part of the crash test assessment. So, cars that are not fitted with the AEB car brakes will not get the 5 star rating for road safety. Michaels Van Ratingen the secretary general of the Euro NCAP says…

“We don’t want to force the car makers into this immediately, but we’ve made it very clear that the best way to ensure a five-star rating from 2014 is to have AEB on the vehicle,”

He must be disappointed though because at the moment only just over 20% of new cars have the new system fitted.

Your car  will, be much safer with the new car brakes system fitted

The new brakes technology will reduce my quoter of near misses. Importantly, that I have nearly had in the past year. So and reduce the number of small bumper to bumper accidents and hopefully “whiplash claims”. It’s a new system that uses radar, lidar (laser) and also video technology. Happily, to warn the driver of an impending frontal collision. This must happen to all of us on the congested roads here in the UK. Before priming the brakes and eventually performing an emergency stop.

The new system is expected to save up to 8000 lives in the EU Countries alone, but not everyone agrees and thinks that better driver training (as in my case) would be a better option, he says…

“Although you are right to a small degree in that “advanced driver” are predisposed to better driving. Including the techniques they use are hugely influential. To prove my point.

I train learner drivers using the system of car control and commentary skills. In the last decade I have only had one pupil seriously injured in the two years after they passed their test. She was hit by a stolen car, traveling at double the speed limit, on the wrong side of the road and coming round a blind corner. I do not select my pupils by their predisposition to advanced driving, but I do train them to a much higher standard than is required for the driving test.”

In my opinion it will be the same problem as ABS car brakes.

It is alright if your car has them fitted. But not the other guy who doesn’t have them fitted. Until all cars have the new In my opinion it will be the same problem as ABS car brakes. It is alright if your car has them fitted. But not the other guy who doesn’t have them fitted. So, it is going to be a lottery of the does and don’ts. If a line of cars all have to slam on. You will stop because you will have the new car brakes system fitted. But the car at the back of you may not stop because he has not got the new car brakes system fitted.

All new rules and technology are going to help the motorists in today’s heavy traffic and I am all for safety measures that will help this cause. In my opinion this is a great idea. It will also save the future lives of some cyclists and pedestrians, so there is no reason to be negative about it. This is one of the best ideas to come out of the EU Parliament, amongst all the other rubbish that they dish out.

I am not sure if the car manufacturers will be using standard systems or doing their own thing, but as a garage owner I say “bring it on”. Brakes safety is one of my biggest promoted subjects and the AEB system, will be a great advantage to us in the long run when they are fitted to all cars as standard

Car Brakes-Entering the FRICTION ZONE — Older vehicle PARC sees increase in Car brakes sales

Entering the FRICTION ZONE — Aging vehicle parc ripe for car brakes sales Car Brakes-Entering the FRICTION ZONE

Tire Business

“Where before when a vehicle reached 10 years or 11 years, consumers were thinking of selling it, now they’re thinking of, ‘How can I keep my car going?

Eric Roberts‘s insight:

This is a very in depth articles about car brakes

Un-reasonably,  car brakes are very often taken for granted. So, in other words car owners will just pull into your garage and leave their car. Because there is a banging or rattling noise coming from the front of the car.

This is usually a good indication that the brakes have failed, or are failing ! But brake jobs do follow a pattern.

The spring time is usually the time for our customers car brakes to start going wrong . So, and needing repairing. Of course, in my opinion I think that it is because that drivers use their  brakes. Of course, much more in the winter months and therefore the brake pads and discs .

Drivers almost always wait until the last minute to have them repaired and consequently cause more damage to the brakes.

For example a simple job like a set of brake pads replacing may turn out to be more complicated and end up the car needing new discs, or a seized up brake caliper.

This will result in a larger garage invoice for the customer. The secret is to get a free brake check at your local garage. most garages here in the UK will give a car a free brake check and give the customer a quote for the required work. We are members of the Independent Car Care Centres who also offer a nationwide guarantee throughout the UK and a free brake check on all makes and models of cars.

All this culminates as a good time of year for doing brake work, especially the many older cars that our customers are now hanging on to longer and having them repaired instead of replaced.

Braking Problems Highlighted- Check your brakes after the lockdown park up

Braking Problems Highlighted

Braking Problems Highlighted

Of course your cars brakes are really important. Surprisingly, we still get cars presented to us with brake pedals that almost touch the floor of the vehicle! So you would not believe the number of cars that are driving about with insufficient braking power. You really have to press the pedal with all your might to stop the car!

Braking Problems Highlighted-brake fluid levels require regular checks

So, this article comes as yet another reminder to my customers and the motoring public in general. Regular servicing ensures that your brake levels , including your master cylinder are checked. Of course not only checked but topped up tot he correct level. At the moment I an writing this important post in the middle of the “covid 19” pandemic.

As a result millions of cars have been parked up and stood down. We were all told to stay at home to fight this terrible virus. Vehicles were no doubt neglected. Consequently, braking systems for ne reason or another would have become “spongy”. This is due to air getting into the brake system for one reason or another. Especially when the brakes were not used.

As I am writing this there will be motorists who will remember having to pump the brake pedal to enable them to get a good braking response. So, in my opinion I would recommend that you should call into your local independent garage and at least have a brake check. Preferably though as part of a service.

I have personally experienced brake failure and believe me it is no fun when you press the brake pedal and the car does not stop.

MOT testing back on track

Another thing effected by the government lockdown was a suspension of MOT testing. Because people were in lockdown then the government in there wisdom decided to make my life even more miserable by suspending MOT testing. However now that this period is over then cars will still have to be tested. Backlogs are inevitable as thousands of motorists will try book their cars into their favorite garages. This will be a great time to take advantage of one of the deals that small garages can offer. For example, here at pellon Autocentre we will offer the customer an MOT test and service for just £100.

naturally this will also alleviate any anxiety about the cars brakes. As they will be thoroughly check on the service and then sanctioned on the MOT.

Brake Problems- A good look at some common problems with Master Cylinder Auto Repair – Brakes Don …

Home » All Car Servicing » Brake Servicing Halifax

Brake Problems

Brake problems can be difficult to diagnose, but most drivers encounter these common symptoms: your brake pedal feels soft or mushy, when braking, your foot

Eric Roberts‘s insight:

Master cylinder brakes  fluid may need checking at regular intervals

This Brake Problems video and article written by Joyce Blay is well worth looking at. We in the garage and Autocentre sector are always advising the motorists. Of course, about how they should look after their cars. However, we cannot over stress the important of the cars braking system. Including, how important it is to have your brakes checked. By a professional mechanic or your local garage to avoid future Brake Problems.

The levels that are checked under your bonnet (hood) . Importantly,will include the level in your master cylinder. The lack of brake fluid in the Brake Master Cylinders will lead to spongy brakes and if not corrected will end up in Brake Problems and even brake failure.

Brake Problems

So have these levels checked and if required you may need a complete brake fluid change. This is something else that is recommended by the car manufacturers at intervals. So it is well worth checking to see what intervals this job should be done at. Also if you are topping up the master cylinder yourself, make sure you use the recommended type of fluid for your model, some are different to others, your user’s manual will tell you which fluid to use. These procedures may help eliminate any braking problems for the future!

brake revolution

Of course as time has gone by then brakes have become much more complicated. So one of big advances has been the introduction of ABS to our braking systems. Important to realise that in my life time then braking systems have improved beyond recognition. That is to say that when I was an apprentice mechanic then most regular cars only had drum brakes fitted front and rear.

Later cars that were in the upper class bracket such as Mercedes were fitted with disc brakes at the front. Developments were coming out of the racing car circuits. Consequently, technology would be passed from the racing circuit onto the every day regular cars. Motor racing sped up the developments of all aspects of the modern cars. Up to the latest developments! Including, the introduction of the AEB (Automatic Emergency Braking).So, this system will detect a potential vehicle impact and automatically apply the braking system.

To be truthful I am not sure how this is going to work but I am sure that it will be another brake system success.

CHECK YOUR CAR BRAKES REGULARLY- Regularly Checking your Cars Brakes Could Save Your Life ?

Home » All Car Servicing » Brake Servicing Halifax

CHECK YOUR CAR BRAKES REGULARLY

CHECK YOUR CAR BRAKES REGULARLY

Along with your tyres , your car brakes are the most important (and sometimes most neglected) part of your car. I have been guilty of neglecting my brakes. Especially, when I was a young man. When I was a young mechanic, I borrowed a car from my then boss Peter.

Peter said that I could but I must check the car brakes. Also. the engine levels before setting off on my journey. I was heading for Blackpool. So, a seaside resort on the West coast of the UK. On our return home we started to pass through a town called Preston.

I was doing the statutory speed of 30 mph and was approaching a pedestrian crossing. Of course I should have had to stop. But, when I pressed the brake pedal.Then there was nothing there.Hence, the pedal went straight to the floor boards.

Consequently, I had to swerve the car to miss a guy walking across the crossing. Ending up on the pavement (side-walk). I rapidly pumped the pedal and managed to get some brakes. Thus, on the pedal. Luckily, the vehicle came to a stop. My  friends and I managed to push the car to a garage filling station. Of course, a hundred yards down the road.

CHECK YOUR CAR BRAKES REGULARLY

 I lifted the bonnet (hood) only to find that the car brake fluid was at zero level.So. in the fluid reservoir. I felt a cold chill down my spine. Because, I remembered what my boss Peter had said. Just the day before we set off. We managed to buy some Tesco Brake Fluid and topped up the reservoir.

The car brakes pumped about half way up. Luckily the car would stop when I pressed the pedal. So, we limped home back to Yorkshire UK.Subsequently, a rather terrifying experience. Of course, which I vowed would never happen again. Lessons were learned that day. As a result, I am going to spell out a few important things about the care of your brakes. Hence,for you to understand. Before you embark on a journey or indeed at any time that you own a car.

CHECK YOUR CAR BRAKES REGULARLY-Your brakes are a life saver

The British MOT test has been a great step forward towards the safety of our cars and our roads. When your car is having it’s annual MOT test we check everything on that car ( to the  VOSA MOT test specifications). One of the problems of old was the checking of your car brake pipes.

Brake pipes connect all your four wheels braking system and the cylinders and brake pedal, and are fixed under the car, exposed to all the elements. They are protected by a special coating of wax-oil or sometimes just grease.

Despite all the protection.The Corroded Brake Pipes would rust and then start to leak the brake fluid, eventually causing the brakes to fail,similar to what happened to me in Preston.

CHECK YOUR CAR BRAKES REGULARLY for corrosion

The MOT test makes sure that all your brake pipes (lines) are in good working order and if not the car will fail the test and the pipes will have to be replaced. If you are not sure about the condition of your brake pipes you can get them checked out at your local independent garage, free of charge, or the local garage that you use at the moment.

You must always check the brake fluid in the reservoir under your bonnet and top it up if required with the correct fluid. Check your brake pedal it should feel nice and solid, if it goes too far down then have yours checked by a professional garage or mechanic, don’t take risks, you should not have to pump your pedal to get a good brake.

You brake fluid should be changed every so often, this can be done when you have your car serviced, your local garage will be able to ascertain when, by looking it up on his service
computer for your model of car, we use the Autodata system for checking out the fluid change times.

CHECK YOUR CAR BRAKES REGULARLY Including the Fluid Levels

Also you should check your Disc Brakes and Car Brake Pads. These are the parts that constantly wear out and need replacing with Brake Pipe Kits when they get down to a certain thickness.

When the pads wear down to the the metal part of the pads, then this is when you can hear a loud grinding noise that frightens the driver to death. Once again if this happens then you should have your car brakes checked by a professional mechanic or your local garage.

Once again if you have your car serviced when you have your annual MOT test then your brakes will be checked and should be fine for the next year to come. If your brake pedal does not feel right or goes further down than it should before you get a brake, then have the car checked out do not continue to drive before the car is checked by an expert.

Mazda 5 crawls in with Brakes Problem making a bad Grinding noise?

Home » All Car Servicing » Brake Servicing Halifax

Mazda 5

Mazda 5 brakes make grinding noise

One of the benefits of been an independent garage is the huge diversity of cars that pass through our doors, and our ability to service and fix most of them. I say most of them, because we do have some problems with electrical faults, that can’t be detected without specialists equipment and so in that case we have a couple of different guys who are mobile  electrical specialists. Otherwise we can cope with most car problems.

One popular car to run about Halifax UK, is the Mazda 5. The most popular ones being the different Mazda sports cars, that in my opinion were a similarity to our own beloved MGB sport cars, they all look very much alike.

Mazda’s have come a long way since the 1960’s, when they were inspired by the development of the NSU and the Wankel engine. I remember this little car very well; a mechanic friend bought one and showed me the strange engine that was belt driven. The car was also very fast once it got going and the guy used to frighten me to death: eventually the engine blew up and the car was scrapped.

Mazda were very interested in the German technology

So the Japanese car company formed a business alliance. Of course, with the German car company NSU. In 1967 Mazda started to make a limited production model called the Cosmo Sport and eventually became the sole makers of the Wankel engine, this was only because all the other car companies had given up making the rotary engine.

The Mazda car company was beginning to get a good reputation and started exporting their cars from Japan, both the rotary engine and the standard type piston engine layout, all over the World. These cars were primarily the rotary engine cars, especially the RX models, the RX 2, 3 and 4, were the biggest sellers.

In recent years many other very reputable models were introduced to the UK car market and this brings me onto the Mazda 5 that came into us with brake problems. The customer

originally rang us up for a Brake Replacement Cost, but we explained that we could not tell what the problem was until we removed all the wheels and inspected the Car Brakes including the Car Brake Pads, to see what the problem was.

The customer was a lady with a couple of children and we promised to do the best price for her. This Mazda 5 is a very fuel efficient car with great style and with the performance is a very desirable people carrier and so is very popular as a family car.

The Mazda was left with us for the day with a promise to call the lady with a Brake Repair Cost, as soon as the problem was assessed.

We pulled the car onto the car-ramp and removed all the wheels for a brake inspection

The original problem on the Mazda 5 was that the car brakes were making a terrible grinding noise and we soon found out why? The front brake caliper’s was half seized up. This means that only one of the front Brake Pads were actually working. The one pad that was doing the work wore out quicker than the other pad. Until it went down to the bare metal. Hence,this is what had made the terrible grinding noise. From the front of the car.

The other front Disc Brakes were also in need of replacing and so we gave the lady an estimate and we were given the go ahead to do the work on the Mazda 5. Luckily the brake caliper could be freed off, using a little heat and did not need replacing. All the other parts, the discs and pads were replaced. The rear brakes were in good condition and only required a clean-up and the drums replacing.

This type of problem is a common fault with brake discs. Thus, is one of the reasons that you should have your car and your brakes serviced. Of course, here in the PellonAutocentre Halifax area we service car brakes on most car makes and models. In a service one of the things that we do is to clean and grease the caliper’s. So that they do not seize up and frighten the customer to death. Especially, when they hear the dreaded grinding noise of metal on metal. Naturally, when their brake pads wear out.

The job was completed and the happy customer picked up her car in the evening.

Pellon Tyre and Auto-centre offer Mazda 5 car and van servicing and repairs to all makes of vehicles.

Car Hand brake- Car Repair MYTHS ? Hand Brake (Parking Brakes) Customers always want it Checking?

Home » All Car Servicing » Brake Servicing Halifax

Car Hand brake

Things that motorists still ask for when having a car repair.(Car Hand brake)

Consequently, this is an article about some of the things that motorists ask for or ask us to check. Hence, when they leave their car with us for servicing. I have to admit that most of these guys are male. Thus, from the older generation of motorists.Naturally, who remember some of the problems that they used to encounter in the past. Of course, on some of the older model cars that were driven then.

Therefore,one of the most asked questions is “Can you just adjust my Car Hand brake”. This comes from the days when I was a young mechanic. So all you had to do to adjust the hand brake on most regular cars. Was to take out a split pin, and turn a screw thread. Of course, to either lengthen or shorten the hand brake cables.Thus giving you more leverage from the handbrake in the brake shoes.

When the handbrakes finally snapped with rust or age. Then, all you had to do was replace it with a new cable,”simple”. This type of hand brake system was always failing. Especially, when you pulled on the hand brake.So, the cable would snap. This, was responsible for many an accident.With cars parked on hills running away. However, this is the type of Car Hand brake that some motorists think their car is fitted with. Thus,thinking that it is only a ten minute job to adjust (at probably no cost to him ).

(Parking Brake)

As the modern car progressed. So it was clear that better braking systems had to developed. As a result, cars were getting faster, then they had to stop more efficiently and quickly. This brings us up to date. Consequently, with more and more car manufacturers using discs on all four corners of their cars. Not fitting the drums system at the rear. (Some newer cars still have drums at the rear, but more are favouring four wheel disc systems, for greater braking efficiency). Modern cars also have a separate handbrakes system. Including, their own drums system. Thus, working in conjunction with the rear discs. of course, which are virtually a separate system from the main brakes. Many cars are now fitted with duel cables. So, that are better protected from the outside elements (corrosion) .Most Car Hand brake on modern cars are much more complicated to service. Of course, now are one and two hour jobs to complete. Some smaller cars have still got rear drums. A Car Hand brake that works by connecting to the Rear Brake Shoes. Requiring freeing off from time to time. Also and lubricating as part of a regular service. But I am afraid that the cables still seize up and have to be come to us for a Car Hand brake Cable Replacement  from time to time especially as the car gets older.

brake is now a different animal?

In the more up to date modern car with disc brakes all round there is an additional lever and cork screw mechanism that is added to the calipers piston. When the driver pulls the hand brake on in the car, the lever forces the cork screw against the same piston that activates the foot pedal system.

This system also has problems with seizing parts and will take more than ten minutes to free off and lubricate for further use. There are other systems such as used by Volvo, that incorporate a separate drum with its own Ferodo Brake Shoes that is connected to the rear discs, this can also be a long job to service correctly.

To summarise the “can you just adjust my Car Hand brake” days are over, we as a garage need to take more time to repair and adjust the modern car hand brake system and indeed what we do is to offer a separate service just to do the cars braking system justice and to offer a first class brake service.

Mercedes Vito Brakes Job Turns up Horror Shock Absorber

Home » All Car Servicing » Brake Servicing Halifax

Mercedes Vito Brakes

So, I must admit that I am a great fan of the Vito van. Because, a few years ago then I owned a beautiful red Mercedes mini-bus. Fortunately,  the vehicle was very reliable. Requiring very little maintenance apart from the normal servicing and the usual tyres and other renewable. As most of my readers now know then my wife and I had eight children. So we needed a large vehicle to transport the family about.

We also did much travelling! Especially, to France, where we spent most of our summer holidays. Unfortunately, the only downside came when we tried to sell the Vito. Positively, it was in great condition. Being a garage owner, then we had the van service at very regular intervals. Brakes were a prime consideration. Because the safety factor when travelling long distances.

So, we advertised the van in all the usual places. Including online web sites. Finally we received an offer from a taxi guy from Chester. The price he offered was below the price that we were asking but we reluctantly let the Vito go.

Same colour Vito in for Brakes

Last week when visiting the garage in Halifax . So, I noticed a red Vito on one of the ramps having some work done. Significantly, the rear wheel were removed and the brake calipers were hanging down. Dale one of my mechanics was working on the van at the time. Asking what was wrong , Dale explained that the van had braking problems and indeed required a full brake rebuild on the rear brakes.

However when removing the rear wheels then Dale discovered an horrific problem ! The rear shock-absorber had completely broke off and was just hanging there! This can be clearly seen in the above image. Unfortunately, the break was from part of the chassis. Serious rotting had taken place in the shocker mounting area. Welding was not an option ! So, to correct this problem then a complete new chassis box section would have to be engineered. Consequently, this is above our remit and would have to be done by a specialist body repair shop.

After contacting the customer we were instructed to carry on with the Mercedes Vito Brakes. As a foot note the customer said that he had never any banging or strange noises at all. I find this hard to believe with a shocker hanging down ?

Jaguar XF Brake Problems ? Hub Rusting the main Culprit?

Home » All Car Servicing » Brake Servicing Halifax

Jaguar XF Brake Problems

We are fortunate to have a few of our customers who own a Jaguar XF.

So, like most older guys I have always been a keen fan of the Jaguar cars. Going back to when I was a young man working in a garage, as an apprentice mechanic. We were fortunate enough to have some wealthy customers. Importantly, who could afford to buy new Jaguars from time to time.

One of them was one of the directors of the Fox’s biscuits empire. Hence, who was one of the Fox families. Luckily, he always had four or five new cars on the go at once. Consequently,who always kept us busy with the servicing and repairs.

Jaguars have always appeared to have brake or tyre problems. So, throughout their history. I can remember in the late 1960’s the new  XJ4 came onto the market. This car sported wonderful flared archers . Including, new 6×15 inch wheels that were fitted out with a new tyre form Dunlop tyres. Subsequently, the tyre size was ER70VR15.

These  tyres were especially designed for Jaguar by Dunlop.

Dunlop were developing tyres with the Jaguar engineers. Who at that time were a major force in the UK tyre market. Importantly, this car also came out on disc brakes all round.

I always remember the problems that the XJ4’s were having with vibrations. Annoyingly, coming through brakes and the steering wheels. Firstly, it turned out that one of the problems was engine vibrations. So, Jaguar engineers tried out many things. Of course to try and correct the problems.

I then worked for National Tyre Service who was wholly owned by Dunlop. It was our task to try balance the wheels to our best ability. But in those days we did not have the sophisticated electronic equipment that we use on today’s cars. In fact we had to take the cars to the Dunlop garage in Leeds. Strangely at the time this was done in secrecy.  Because of the huge problem that Jaguar was having with these vibration problems.

I was once able to stop and watch the engineers go to work balancing the wheels

The balancing was carried out on a special machine that I had never seen before.  It must have been brought to Leeds from the Dunlop factory. The most amazing thing was that the Dunlop technician actually skimmed some of the tread off the tyres. Trying to make them

rounder. I certainly know that all this was hush/hush. Incredibly, so not to affect the reputation of Jaguar and also Dunlop. I believe that Jaguar had to do all sorts of things to correct the vibrations problem !  An excellent article about the early Jags can be found on…Aronline .

Back To the future with the Jaguar XF

As I have said before !  We have three or four customers that come into us for servicing. Including other jobs doing on their Jaguar XF. We have had a couple of these with complaints about brake vibrations and a droning noise. One of our customers came in with brake problems similar to the others.

This one was a bit different in that the problem  did not occur  when he was doing high speed ,the car was smooth, but when he started to slow down to about  60 mph and then 40 mph the vibration and droning noise would start to happen.

The problem is, like so many of these things, that when we road test the cars the problem never shows itself up, the car plays mind games with the owners. This particular car was taken back to the main dealers, but we now know that the braking and droning noise is now a recognised fault, the cause is thought to be the disc brakes or hub run out.

Another Jaguar XF that we were servicing was found to need discs and pads all round.

We contacted the customer who kindly gave us the go ahead to do the job. He gave us his consent and we carried out the brakes work. About three months later the car had developed a slight brake vibration and he left the car with us for examination. This all reminded me of our problems with the XJ6, s Jags in the sixties.

We road tested the car a sure enough the brakes pedal did vibrate slightly. We could find nothing wrong and true to our warranty policy we suspected that the discs could be faulty and  ordered a new set of discs.

Our supplier agreed to change the discs and accordingly sent us a new set. The New Jaguar XF discs fit onto the hub and we noticed that a slight amount of rust had formed on the outer part of the hub; this can be seen on the pictures that we took.

We think that we cured a previous Jaguar XF by removing any rust and thoroughly cleaning the hubs

Of course, before refitting the brakes discs. When we did this on this particular Jag it appeared to solve the problem. So, we cleaned off any rust that had formed on the hub. Thus, where the discs seat and re-fitted the replacement discs. Ryan road tested the car and all was well, the car had no brake vibrations and so far the car appears to be working fine.

We now think that this could be a problem if you are lucky enough to own one of these fine cars. Please make sure that the hubs where the discs fit are totally cleaned and look like new, because any rust build up will cause the disc to run out of line, only a fraction, but we feel it would be enough to cause a brake vibration on the Jaguar XF when the pedal is applied.
