The disc brakes are of hydraulic type and controlled by hydraulic pressure. The main components include brake discs, sub-pumps, brake calipers, and tubing. Disc brakes provide fast heat dissipation, light weight, simple construction, and easy adjustment. In particular, high-temperature performance at high load is good, the braking effect is stable, and mud is not afraid of attack. In winter and bad road conditions, the disc brakes used in many cars have flat brake discs, perforated brake discs, and strokes. The linear brake disc, in which the brake effect and ventilation and heat dissipation capability of the streak-type brake disc are all better.

　　The disc brake applies force along the brake disc, the brake shaft is free from bending moment, the radial dimension is small, and the braking performance is stable.

　　Application

　　Disc brakes have been widely used in cars, but most of them are used as front-wheel brakes except for all the wheels used in some high-performance cars. They are used in conjunction with the drum brakes of the rear wheels in order to have high braking speeds. The directional stability. In trucks, disc brakes are also used, but there is still a considerable distance from the popularity.
