Automotive brake pads are generally composed of steel plate, adhesive insulation layer and friction block, steel plate to be coated to prevent rust, coating process with SMT-4 furnace temperature tracker to detect the temperature distribution of the coating process to ensure quality.

The insulation layer is composed of materials that do not heat transfer, and the purpose is to insulate. The friction block is composed of friction materials and adhesives, and is squeezed on the brake disc or brake drum when braking to produce friction, so as to achieve the goal of vehicle deceleration and braking. Due to friction, the friction block will gradually be worn, generally speaking, the lower the cost of brake pads wear faster. After the friction material is used, the brake pads should be replaced in time, otherwise the steel plate and the brake disc will be in direct contact, and eventually the braking effect will be lost and the brake disc will be damaged.
