Background technique

Brake pads are also called brake pads. In a car's braking system, brake pads are the most critical safety parts. Brake pads are generally composed of steel plates, bonded insulation layers and friction blocks. The friction blocks are composed of friction materials and adhesives. During braking, they are squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of decelerating the vehicle. , an appropriate and stable friction coefficient is one of the most important technical indicators of friction materials, which determines the basic brake pad braking torque. Usually it is not a constant and changes with temperature, pressure, speed or surface state and friction environment. When affected by these factors, the friction coefficient changes less, which is the ideal friction coefficient. The national standard strictly requires manufacturers to indicate the friction coefficient on the packaging. The friction coefficient must be appropriate.
