Due to the wear and tear on the surfaces, discs are frequently changed during the life time of a vehicle. Usually this is mileage related, but also the vehicles use and weight can mean more frequent changes.

You should expect to have it done once your car has covered anything between 15,000 and 50,000 miles.

A visual examination of the braking system of your car is included every time it is serviced

As with most parts of your car, the less pressure you put on any part of your car’s brakes, the longer they will last. If you carry heavy loads frequently, or tow a caravan for example, your brake system will come under greater pressure than it would otherwise and as such the discs may wear prematurely. Therefore, removing unnecessary weight from the vehicle will not only improve your fuel consumption, it will reduce the wear on the brakes.

Also consider your driving style. Anticipating the road conditions ahead, keeping your speed as constant as possible, and thereby avoiding sharp braking are all likely to lengthen the interval between brake disc replacements.

Brake discs will gradually become thinner due to the friction between them and the brake pads.

This wear and tear can be hastened by inappropriate brake pads being fitted, worn brake pads and excessive hard braking. If you can see a rough surface you brake pads will feel it! It will be like running the pads over a cheese grater and they will wear out very quickly!

If the brake discs have worn out prematurely or if you are experiencing trouble under braking, it is advisable to seek the help of an expert to investigate the problem and, if necessary, replace the discs as soon as possible. Driving with brakes that do not function properly can, of course, lead to dangerous situations on the road.

Brake discs are supplied and fitted in axle pairs (i.e. front or rear). It is equally important to have new brake pads fitted at the same time otherwise any wear pattern on the pads from the previous discs could severely reduce the contact area between the two. This is so important that no mechanic would consider doing otherwise.

Yes, if you are told the brake discs need replacing then this will need to be done in conjunction with the brake pads. If it is has been professionally diagnosed that just the brake pads are worn and have caused no damage to the discs then it is not always needed to replace the discs at the same time. At ClickMechanic we offer brake discs and pads replacements as well as brake pads replacements. If you are unsure which brake parts need replacing then book with a professional mechanic who can check the brakes and advise on next steps. If you experience any untoward characteristics in your braking, book a diagnostic inspection immediately and do not drive the vehicle.

The average life of brake discs will depend on a number of factors, generally disc brakes should last at least 75,000 miles. The way you use your vehicle, how you brake, the quality of the brake parts used and workmanship will ultimately all have an effect on how long brake discs will last so the lifespan can be shorter or longer than average.
