ABSTRACT:
An anchor plate is disclosed for a drum brake assembly having a backing plate and a pair of brake shoes arranged in end-to-end relationship thereon. The anchor plate engages a knob integral with the backing plate, the knob extending from the backing plate a distance to extend into the plane defined by the brake shoe webs. The backing plate knob defines a pair of knob faces, each knob face facing a corresponding brake shoe web. Disposed in overlying and force-fit engagement with the knob is an anchor plate of thin material having a planar surface and two substantially perpendicular tabs extending therefrom. The tabs define load bearing surfaces for receiving the brake shoe webs. The tabs are spaced apart a distance equal to, but preferably slightly less than, the distance between the knob faces for snug intereference fit therewith. The planar top surface of the anchor plate has, integral therewith, retaining tabs extending substantially parallel to, and overlying the brake shoe webs. The anchor plate is preferably secured to the knob by a single rivet that passes through complementary openings in the anchor plate and knob.
