ABSTRACT:
A brake shoe assembly incorporates unitary retainers for anchor pins about which a pair of brake shoes may pivot. In a preferred form, the anchor pin retainers are spring steel structures formed of drawn heat treated wire, each retainer defining a pair of spaced legs joined at one end by an arcuate or bowed portion adapted to engage one of a pair of spaced grooves in one of the associated anchor pins. Each brake shoe contains a web portion which includes a cradle for pivotal support against an anchor pin. Each web has a pair of apertures disposed for engagement by a hook formed at the end of each retainer leg.
