Description

technical field [0001] The invention belongs to the technical field of brake pads, and in particular relates to a composite fiber-reinforced brake pad resistant to heat decay. Background technique [0002] Brake pads, also called brake pads, are the most critical safety parts in the car braking system, and play a decisive role in the braking effect. The working principle of the brake is mainly from friction, using the friction between the brake pad and the brake disc (drum) and the tire and the ground to convert the kinetic energy of the vehicle into heat energy after friction to stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities, so as to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder And each cylinder, and to avoid hydraulic failure and brake fading...
