The principle of brake pads is mainly to convert the kinetic energy of the vehicle into heat energy through friction, thereby achieving deceleration and stopping. When the driver steps on the brake pedal, the brake fluid enters the brake device through the brake line, applying pressure to make the brake pads and the brake disc (or brake drum) in close contact. As the vehicle moves, the brake pads rub against the brake disc (or brake drum), generating friction, converting the kinetic energy of the vehicle into heat energy, thereby slowing down or stopping the vehicle.
Brake pads play a key role in the automotive braking system. It is one of the core components of the automotive braking system and is responsible for providing the necessary friction to slow down the vehicle. A good brake system can not only provide stable, sufficient and controllable braking force, but also has good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal can be effectively transmitted to the master cylinder and each sub-cylinder, and avoid hydraulic failure and brake decay caused by high temperature.
