Brake pad

The invention discloses a brake pad, relates to the technical field of brake devices, and aims to prolong the service life of the brake pad and avoid potential safety hazards caused by uneven stress and heating in operation. The brake pad comprises a steel backing assembly and a plurality of friction particle assemblies, and one side face of the steel backing assembly is provided with a first arc-shaped face. A plurality of friction areas sequentially arranged in the radial direction of the first arc-shaped face are arranged on the surface of the steel backing assembly, and the extending direction of the friction areas is parallel to the first arc-shaped face. The multiple friction particle assemblies are arranged on the steel backing assembly, each friction particle assembly is provided with a friction face used for making friction contact with the brake disc, and the area, located on the friction area in the middle, of the friction faces of the multiple friction particle assemblies is close to the area, loc
