ABSTRACT:
A brake assembly, for a vehicle axle having a beam, including a spider mounted on the beam, a camshaft mounted on one end of the spider, a pair of anchor pins mounted on an opposite end of the spider, and a pair of brake shoes. Each of the brake shoes has at least one bearing surface disposed at one end thereof mounted on an outer portion of one of the anchor pins and a roller mounted on an opposite end thereof operatively engageable with the camshaft. A spring interconnects upper portions of the brake shoes and pivotally biases the upper ends of the brake shoes toward each other into retracted positions. A retainer adjacent the anchor pin ends of the brake shoes biasingly urges the bearing surfaces of the brake shoes into engagement with the anchor pins. The retainer is a U-shaped spring element having a hook section at each of its free ends encompassing the anchor pin ends of the brake shoes. The retainer includes a base section engaging an anchor pin end portion of one of the brake shoes and a pair of leg sections projecting from end portions of the base section toward the other of the brake shoes. The hook sections are disposed at the free ends of the leg sections and engage the other one of the brake shoes in hooking relation. Portions of the leg sections of the U-shaped retainer engage both ends of the anchor pins thereby preventing their axial movement.
