[0002] Brake is the device with the function of making moving parts (or moving machinery) deceleration, stop or keep stop state etc..It is the mechanical part of making moving parts in machinery stop or deceleration, commonly known as brake, brake. Brake is mainly composed of brake frame, brake piece and operating device etc..Some brakes are also equipped with automatic adjustment device of brake piece gap. In order to reduce brake torque and structural size, brake is usually installed on the high-speed shaft of equipment, but for the large equipment (such as mine hoist, elevator etc.) with higher safety requirement, it should be installed on the low-speed shaft near the working part of equipment. Brake can be divided into two categories, industrial brake and automobile brake. Automobile brake is also called automobile brake controller.

[0003] Automobile brake controller is divided into running brake (foot brake), parking brake (hand brake) and balance force amplifier brake.
