[0002] The car brake disc is one of the important components of the car brake system. It is also called the brake disc or brake disc. Its function is to cooperate with the brake caliper and brake pad to generate braking force through friction to slow down or stop the vehicle. The seal of the brake disc plays an important sealing role. After the seal is produced in the factory, the thickness of the seal needs to be tested.
