Brake lining is generally composed of steel plate, adhesive insulation layer and friction block. The steel plate is painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process. quality. The insulation layer is composed of a material that does not transfer heat, and is intended to be insulated. The friction block is composed of a friction material and an adhesive, and is squeezed on the brake disc or the brake drum to generate friction when braking, thereby achieving the purpose of decelerating the brake of the vehicle. Due to the friction, the friction block will gradually wear out. Generally speaking, the lower the cost, the faster the brake pads wear.
