[0002] Brake pads, also known as brake leathers, refer to the friction materials located on the side of a car's brake drum or brake disc. Brake pads are one of the most critical safety parts in a car's braking system. They are generally composed of steel plates, adhesive insulation layers and friction layers. When braking, the friction layer is squeezed onto the brake drum or brake disc, and the purpose of slowing down and braking the vehicle is achieved through friction.

[0003] When a car brakes, the brake pad will generate a large friction force, so it will generate heat. In order to protect the car components around the brake pad, the brake pad is provided with a heat insulation layer for heat insulation, and the heat insulation layer prevents the heat from being transferred to other components. The heat dissipation effect of some existing brake pads is poor. A large amount of heat during braking is accumulated on the brake pad. The high temperature will not only reduce the braking performance of the brake pad, but also shorten the service life of the brake pad. Therefore, a combined brake pad is proposed to address the above problems. Utility Model Content
