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.

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.

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

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

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. 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.
