[0034] Furthermore, the first brake end face 11 is provided with a first step groove 111, and the first step groove 111 is formed with a heat dissipation inner wall 1111 and a heat dissipation end face 1112. It can be seen from the accompanying drawings that the heat dissipation inner wall 1111 is the inner wall of the first step groove 111, and the heat dissipation end face 1112 is the bottom end face of the first step groove 111; through the above-mentioned setting, the present application can utilize the first step groove 111 to compress the thickness of the brake body 1, thereby accelerating its heat dissipation rate during use, and the heat dissipation inner wall 1111 formed can increase the heat dissipation area of ​​the brake body 1; that is, the first step groove 111 can quickly conduct the heat generated on the brake body 1 due to contact with the brake caliper and dissipate heat; providing the first step groove 111 on the brake body 1 can enable the brake disc 100 to have stronger heat dissipation efficiency and safety performance.
