Brake discs

The braking system is an important part of the safety technology of the car, because it reduces the speed of the vehicle or it prevents the car from rolling away. A part of the brake system are the brake discs, which are needed to press against the disc brakes. Some well-known manufacturers of brake discs are BREMBO, NK, JURID, DELPHI, BOSCH, TRW and STARK.

Function and tasks of the brake discs

The brake is applied so that the speed of the vehicle is reduced, then the conversion of kinetic energy into heat energy is carried out. This is the reason why brakes are exposed to very high mechanical loads. Since the brake disks wear out over time, it is necessary to replace them regularly. This is the only way to ensure the operation of the braking system. The brake disc is screwed into the hub, and is usually made of steel or cast iron, and partly out of nodular graphite cast iron or ceramic.

How to recognise wear and tear?

Brake discs must be replaced after high wear and tear. For example, if they are wedge-shaped or just thin. Manufacturers provide a "minimum thickness" of the discs which must be respected, because otherwise the risk is great that the discs can break. Furthermore, there is also the risk that the caliper will bind to the piston. Another indication of worn out brake discs is a vibrating or shaking of the steering wheel when braking. In this case it means that the brake discs are worn different on each side.

Replacing the brake discs. What to consider when replacing the discs?

If you are replacing the brake discs, here is some information to consider: If the disc is due to be replaced due to wear, then you should replace the pair, as this is the only way to ensure your safety. If you do not do this, the braking load will be different on both sides. For this reason, brake discs are only ever offered in pairs, although a skilled person should do the replacement and installation. It should also be considered when replacing if the brake discs and brake pads should both be replaced at the same time. You can buy various brake discs in our shop.
