Brake Juddering Causes-What is it?

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.

Replacing warped discs and worn out pads

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 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

Perforated discs like this BMW disc are designed to dissipate the heat that is built up when braking hard

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 Rule The Day-Another Busy Saturday Sees a Good Mixture of Customer Car Problems?

Car Brakes Rule The Day

As many of my readers will know then Saturday is my favorite day of the week. So the rest of my week is spent working on my computer trying to figure out the best way to please Google and rank my business websites. I have a one man mission to conquer this. So with the help of Yoast, I soldier on.

This Saturday was to be a very busy one. It is the middle of November and our customers are preparing their cars for the Christmas break. Of course this has been helped by the short spell of colder weather. Exciting days for us when the cars roll in desperate for a new car battery to replace the one thats on its way out.

Car batteries to start the day

Of course we are happy to oblige them? My staff have a new toy? Its a great little new battery tester. Naturally, our new battery tester tells the customer that he needs a new battery by giving him a print out. Print outs seem to be what people want. In fact all our electronic testers including our 4 wheel alignment gauges will give out a printout for the customer to see.

Our first two cars that pulled in were in fact to test batteries. Consequently, they both failed and new car batteries were fitted. Also the last car in this particular Saturday was a for a battery fitting on a VW Polo. The car had an 063 fitted as original equipment. In this case we always replace the battery with the one fitted on as the original. We offered the lady one of our own brand Apollo Premium 063 batteries. She was pleased with the price and the battery was fitted.

Brakes take over?

However it was soon to become apparent, when the next three cars that came in all had some sort of brake problems. Saturday, can become difficult with brake problems. Because, not all brake parts are available from our local parts people. Any how this time we were in luck and the brake parts were available for all the cars that came in on this particular day.

Vauxhall Corsa with brake caliper problem

The first car was a young lady in a Corsa D 2007 1.2. She went on to tell us that the the car was bought about a year ago. Of course, she went on to tell us that

Vuaxhall Vectra badly worn discs that needed replacing

the Corsa behaves erratically when braking. Any time I step on the brake pedal, the car will pull towards the right side. So pulling into the centre of the road. Very scary! However it eventually straightens itself up.

Alex went on a short road test. On his return it decided that he needed to remove the wheels. But suspected a seized brake caliper was likely to be the culprit. Sure enough the brakes were visually inspected and both calipers were not working freely. One was worse than the other causing the Corsa to pull into the centre of the road when braking. Alex was able to free one side but the other required a new brake caliper.

Vauxhall Vectra B with noisy brakes

Following just behind the Corsa was a guy with a Vectra brake problem. This was also to be an easy diagnosis. Consequently, the guy had fitted a set of his own pads in preparation for its pending MOT Test. Subsequently, the car had passed the test but had developed the dreaded grinding noise. Grinding must rate up there as the most common brakes fault.

Car Brakes Rule The Day

Worn out brake discs and pads

Once again we had an incline as  to what the problem was going to be. John, one of my mechanics removed the front wheel to examine the discs and pads. Sure enough the guy had fitted new pads but had fitted them onto badly worn discs. So unless the discs are in really good condition then we always change the discs and pads. Because the guy was waiting for his car we showed him his error.

After fitting new discs the brakes were rebuilt and road tested. of course everything was fine and the guy went off a happy customer. Hence, the next two brake jobs were simple discs and pads and the cars offered us with no major challenges. Just what we want on a Saturday. Everything was straight forward.

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

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 throwbacks from our own beloved MGB sport cars, they all look very similar.

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

and the Japanese car company formed a business alliance 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 RX2, 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

Disc and pads worn out. You can see that one on the pads the right hand one,has completely worn away due to the seized brake caliper.

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 and 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 and is one of the reasons that you should have your car and your brakes serviced, 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 when they hear the dreaded grinding noise of metal on metal, when their brake pads wear out.

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