The insulation layer is composed of non-heat transfer material, the purpose is to heat insulation. 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 goal of vehicle deceleration and braking. Because of friction, friction block will gradually be worn, generally speaking, the lower the cost of brake pad wear faster. After the friction material is used, the brake pads should be replaced in time, otherwise the steel plate will be in direct contact with the brake disc, and the brake disc will eventually lose its braking effect and damage it.
