With the improvement of people's quality of life level, the number of people using cars is gradually increasing, and the automobile industry can be said to be an important industry in the national economy.

The braking system is one of the most critical systems in a vehicle. With the expansion of the automotive industry, the demand for braking systems is gradually increasing

We all know that cars are stopped by their brake pads. The working principle of the car's brake system is friction. The car's brake device uses the friction between the brake pads and the brake disc to convert the kinetic energy of the vehicle into frictional heat energy to stop the car.

Many car owners find that some rust is generated on the brake discs of their cars, especially in humid environments. Because the brake disc is made of metal, and the brake disc is in direct contact with the air.

The brake system can be said to be the most important part of a car that affects driving safety. As car drivers, we all know how important the brake disc is to the braking system of our entire car.
