ABSTRACT:
The spring comprises a mounting portion 42 snapped into the arch of the caliper of a sliding-caliper disc brake, and rigid portions 58, 60 for exerting forces on support plates 26, 28 of friction members interacting with the disc of the brake. According to the invention, slits 90, 92 parallel to the rigid portions 58, 60 reduce the rigidity of the central part of these. Thus, when the friction members become worn and approach the center of the spring, an intensification of the forces exerted on the support plates by the spring is avoided. A lug 100 makes it possible to keep the rigid portion 58 away from a fragile part of the brake when the friction members are removed from the latter. The invention is used on sliding-caliper disc brakes.
