Brake discs are an important part of the braking system. If the braking system is to always slow down the vehicle safely and comfortably - bringing it to a complete stop if necessary - the brake discs must combine with the brake pads to generate braking torque (braking force).

Disc brakes are safety-critical automotive components that must meet stringent cost and environmental requirements. Drivers often assess the performance of a vehicle's braking system based on the "feel" of the brake pedal.

In order to ensure the safe operation of the car and improve its average speed to increase transport productivity, a variety of cars are equipped with special braking mechanism. Such a series of specialized devices is called the braking system.

The brake system is the most critical system in a car. When the driver presses the brake pedal, the brake fluid in the brake master cylinder generates pressure.

The braking system is the most critical system in a car, through which the car can be effectively slowed down and braked. A stable braking system provides a strong safety guarantee for the car.
