Brake lining (brake lining) generally consists of steel, thermal insulation and friction pad composition, steel to be coated to rust, coating process using the SMT-4 furnace temperature tracker to detect the temperature distribution of the coating process to ensure quality. The insulation is made of a material that does not transfer heat for the purpose of insulation. Friction block by the friction material, adhesive composition, the brake is squeezed in the brake disc or brake drum friction, so as to achieve the purpose of vehicle deceleration brakes. As the friction effect, the friction pad will gradually be worn, in general, the lower the cost  brake pads wear faster.

The working principle of the brake is mainly from the friction, the use of brake pads and brake discs (drums) and tire friction with the ground, the kinetic energy of the vehicle is converted into friction heat, the car stopped. A well-functioning brake system must provide a stable, adequate and controlled brake force with good hydraulic transmission and heat dissipation to ensure that the force applied by the driver from the brake pedal is fully transmitted to the master cylinder And the sub-pump, and to avoid the heat caused the hydraulic failure and brake recession.
