What is the structure of car brake pads

The thermal insulation layer is composed of non-transfer materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, thus achieving the goal of vehicle deceleration and braking. As a result of friction, the friction block will gradually be worn. Generally speaking, the brake pads with lower cost will wear faster. After the friction material is used, the brake pad should be replaced in time, otherwise the steel plate and the brake disc will contact directly, and eventually the brake effect will be lost and the brake disc will be damaged.
