What are the differences between brake disc and brake block?

There are three differences between brake disc and brake block, shape, operation mode, and replacement time. In the daily use of a car, the braking system plays a very critical role.

Different shapes

Brake disc, also known as brake rotors, is mainly made of metal. With many air ports on the surface and a small ring inside, it is round in shape and resembles a CD disc. Brake block, also known as brake skin, is mainly made of ceramic, metal, and carbon fiber. It is a cuboid bearing resemblance to a sponge wipe. It typically consists of steel sheet, bonding insulation layer, and friction block.

Different operation modes

During drives, the brake disc rotates together with tyres. It can be fixed by brake calipers for the purpose of deceleration or parking. The brake block serves as a friction block installed in the brake calipers. When the driver steps on the brake, the brake block will be pressed towards the brake disc or the brake drum. Friction force is thus generated to decelerate the car.

Different replacement intervals

The replacement interval usually differs between brake block and brake disc. Such interval is longer for brake discs. It is typically 70 to 80 thousand km of mileage for a front brake disc and 100 thousand km of mileage for a rear brake disc. In contrast, the replacement interval is 40 to 50 thousand km of mileage for a front brake block, and 70 to 80 thousand km of mileage for a rear brake block.
