Abstract
A disk brake wherein the engagement portions of a return spring are prevented from coming out of respective retaining holes formed in the backing plates of friction pads, and at the same time the spring function portion of the return spring is prevented from interfering with the disk. After the caliper has been mounted on the carrier, the return spring is supported at three portions at each end thereof. The spring function portion is contacted by the protuberance, while the proximal end of each engagement portion is contacted by the entrance portion of the associated retaining hole. Further, the distal end of the engagement portion is contacted by the innermost portion of the retaining hole. In addition, the spring function portion of the return spring is bent radially outward of the disk along a recess formed on the inner side of the caliper.
