Since slide-pin support portions and first braking-torque support portions are independent of each other in the body of a bracket included in a reaction force type disk brake, even if the first braking-torque support portions have deflected more or less by supporting the braking torque of a first friction pad, the deflections are not transmitted to the slide-pin support portions. Accordingly, no twists take place between slide pins and the slide-pin support portions. Besides, in the bracket, the support points of the respective slide pins are arranged in a region defined between second and third straight lines, so that even when the braking torque of a second friction pad has acted on the slide-pin support points through second braking-torque support portions as well as the slide pins on account of the shortened distances between the slide-pin support points and bracket fixation points, turning moments which arise about the fixation points are small. Accordingly, a brake caliper is permitted to slide smoothly, and the durability of the bracket for supporting the brake caliper can be enhanced.
