The brake is a component in the braking system used to generate a braking force that hinders the movement of the vehicle or the tendency to move. In addition to various retarding devices, automobile brakes are almost all friction brakes that use the friction between the fixed element and the working surface of the rotating element to generate braking torque.
At present, the friction brakes widely used in various types of vehicles can be divided into two categories: drum type and disc type according to the different rotating elements. The difference between them is: the rotating element in the friction pair of the drum brake is the brake drum, and its cylindrical inner surface is the working surface; the rotating element in the friction pair of the disc brake is the disc-shaped brake disc, which is Both end faces are working surfaces.
