The Working Principle Of Automotive Brake Pads

The working principle of brakes mainly comes from friction. By utilizing the friction between brake pads and brake discs (drums), as well as the friction between tires and the ground, the kinetic energy of vehicle movement is converted into heat energy after friction, which stops the vehicle. 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, to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and various sub cylinders, and to avoid hydraulic failure and brake recession caused by high heat. The braking systems on cars can be divided into two categories: disc and drum brakes, but apart from cost advantages, drum brakes are far less efficient than disc brakes.
