ABSTRACT:
A brake assembly for a vehicle includes a stamped spider member, an air chamber mounting bracket attached to one end of the stamped spider member, a cam shaft supported in the air chamber mounting bracket having an S-cam member affixed to one end thereof, cam spacer selectively locatable on the cam shaft for adjusting the relative position of the S-cam and the spider member, and an anchor pin supported on the spider member opposite from the air chamber mounting bracket with the anchor pin being supported in a cantilevered fashion at one end thereof by the spider member. A pair of brake shoes are provided having an anchor pin end engaging the anchor pin and an S-cam end engaging the S-cam member. Rotation of the S-cam effects pivotal movement of the braking shoes about the anchor pin to brake a vehicle associated therewith. An anchor pin spacer is selectively locatable on the anchor pin to selectively adjust the relative position of the brake shoes and the spider member. A return spring interconnect the S-cam ends of the brake shoes. A shoe retaining spring is connected to the web of each of the brake shoes adjacent to the anchor pin end thereof and extends around the anchor pin for biasing the anchor pin end of each of the brake shoes toward the other through the anchor pin. The shoe retaining spring is spaced inwardly in a radial direction from the shoetable of the brake shoes to shield the shoe retaining spring from the heat generated when the vehicle is braked.
