Brake pads are also called brake shoes. In the brake system of the automobile, the brake pad is the most critical safety part, and the quality of all brake effects plays a decisive role in the brake pad, so the good brake pad is the protection spirit of people and automobiles. The brake pad is generally mainly composed of a steel plate, a heat insulation layer, a friction block, a silencing sheet and a radiating fin, wherein the heat insulation layer is made of a non-heat-transfer material and aims to insulate heat. The friction block is composed of friction material and adhesive, and is extruded on a brake disc or a brake drum to generate friction when braking, so that the aim of decelerating and braking the vehicle is fulfilled. The pads are gradually worn away due to friction, generally speaking, the lower the cost the faster the brake pad will wear.
