In recent years, China's automobile production has maintained a high growth rate, and car ownership will continue to grow, which provides a broad space for the development of China's auto parts industry.

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.

The significance of the braking system in any vehicle is enormous. Its main function is to reduce the speed of a moving vehicle or to bring it to a complete stop.

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.
