Brake pads are also called brake skins. In the automobile braking system, the brake pad is the most critical safety part. The brake pad plays a decisive role in all braking effects. Therefore, a good brake pad is the protector of people and cars.
The brake pad is generally composed of steel plate, adhesive insulation layer and friction block. The steel plate shall be coated to prevent rust. Smt-4 furnace temperature tracker is used to detect the temperature distribution in the coating process to ensure the quality. The thermal insulation layer is composed of non heat transfer materials for thermal insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to produce friction, so as to achieve the purpose of vehicle deceleration and braking. Due to friction, the friction block will be worn gradually. Generally speaking, the brake pad with lower cost will wear faster.
The working principle of braking mainly comes from friction, Using brake pads and discs (drum) and the friction between the tire and the ground convert the kinetic energy of the vehicle into the heat energy after friction, and stop the vehicle. A set of good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capacity, so as to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each sub cylinder, And avoid hydraulic failure and brake recession caused by high heat.
