1 June 2023 Brake disc replacement – when and how often
Most drivers assume that their brake system is working. At the latest when the wear indicator signals that the rear and front brake pads have reached their wear limit, you should replace them. After all, a well-functioning brake system is extremely important for your safety and of all of the occupants in the vehicle. This is why it’s necessary that you, or a mechanic, check the brakes, brake pads and discs, regularly.
How does the braking system work?
A so-called "friction brake system" is used in passenger cars. It converts kinetic energy into heat. The brake pads press against the brake disc or brake drum and so generate friction causing the car to slow down. The car brake fluid transfers the pressure exerted on the brake pedal to the wheel brake. In addition to the friction brake system, electric and hybrid vehicles also have a regenerative braking system. This converts the kinetic energy into electrical energy using the electric motor as a generator.

When should I replace the pads and discs?
Contemporary brake systems will usually wear out after 75,000 miles. How quickly this happens depends on the particular vehicle, its age, the way you drive, and the conditions you usually drive in. Corrosion caused by environmental conditions, e.g. moisture, humidity, and salt can also become an issue that can lead to damage. If you have an older car, the pads generally need replacing sooner than the rear and front brake discs – some wear out after only 25,000 miles. In newer cars, the pads and discs generally get replaced concurrently.

How to recognise when it is time to change the brake discs
If the brake discs are worn, there are several ways to recognise this in time. Especially in newer vehicles, it is now common for an indicator to light up in the dashboard when the wear limit has been reached, signalling to the driver to change the brake discs. Anyone who ignores this is taking a great risk with unpredictable consequences.
In older cars that don’t have an electronic signal to tell you if the brakes need maintenance and you’ll probably first notice when the brake discs begin to make a loud sound. When the wear limit has been reached, a metal pin scratches the brake disc and produces a loud screeching and squealing sound every time you step on the brake; this can also be a sign that your brake discs are overheating. You should not ignore this sound – it signals that it is necessary to change the discs. In addition, reduced braking performance (long braking distance), a pulsating brake pedal, as well as swerving out of the lane during emergency braking, can be signs of wear. You should also not ignore small cracks or other damage to the brake disc. If the time has come to change your discs, we recommend that you take a look at the Brembo brake discs catalogue – here you are sure to find a suitable replacement at reasonable prices.
