What Are the Materials of Brake Pads?
1 Answers
Brake pads are made of materials such as asbestos, semi-metallic, low-metallic, NAO formula, ceramic, and high-carbon fiber. Brake pads generally consist of a steel plate, a bonded heat insulation layer, and a friction block. The heat insulation layer is composed of non-heat-conductive materials to provide insulation. The friction block is made of friction materials and adhesives, which are pressed against the brake disc or drum during braking to generate friction, thereby achieving the purpose of decelerating and stopping the vehicle. The working principle of braking mainly relies on friction. By utilizing the friction between the brake pads and the brake disc, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, bringing the car to a stop.
