A brake is a part of a braking system that is used to produce braking force that impedes vehicle motion or the tendency of motion.In addition to various retarders, automobile brakes are friction brakes that use the friction of the working surface of the fixed element and the rotating element to produce the braking torque.

At present, friction brakes widely used in various types of vehicles can be divided into drum type and disc type according to the different rotating components.The difference between them is as follows: the rotating element in the friction pair of drum brake is the brake drum, and the inner surface of cylinder is the working surface;The rotating element in the disc brake friction pair is a disk-shaped brake disc, with its two end faces as working surfaces.
