With brake caliper control two pieces of brake pads to clamp the brake disc on the wheels. When the brake pads are clamped, the two will have friction between them.
Because of the performance of the vehicle and the speed of travel and the increasing of the day, in order to increase the vehicle at high speed braking stability, disc brake has become the mainstream of the brake system. Because disc brake disc is exposed in the air, making disc brakes have excellent heat dissipation, when the vehicle in the high-speed state to make the brakes or in a short time many brakes, braking performance is less than the recession, can allow vehicles to obtain better braking effect to improve the safety of vehicles.
And because of the rapid response of disc brakes, the ability to do high-frequency brake movements, so many vehicles using disc brakes and ABS systems and VSC, TCS and other systems to meet such systems need to move quickly.
