The working principle of brakes is mainly from friction. The friction between brake pads and brake discs and tires and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction to stop the car. When braking, the brake pads contact the brake disc and generate friction. The existing friction blocks are all in sheet shape, which will be in full contact with the brake disc. The temperature inside cannot be quickly dissipated, resulting in severe high-temperature wear and reducing its wear resistance.

Therefore, a self-cleaning wear-resistant brake pad is proposed to solve the above problems. Utility Model Content
