What affects the wear of the brakes?

Considering the reliability of the brake, the friction index of the brake is very high, especially at high temperatures, it can still maintain a large friction index. That is, there is enough braking friction torque, but generally speaking, the larger the friction index, the higher the resistance generated by friction, and the greater the shear stress on the outside. Therefore, the loss or damage of the raw materials of the friction surface will be more severe, the more severe the wear will be, and the shorter the working life will be. So friction and wear are two aspects that are both related and contradictory during friction. Different working environments and conditions have different priorities. But for brakes, there needs to be some frictional resistance without causing relatively large wear. Brake wear is related to the friction state during friction, and varies with the working environment and the material of the brake.
