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.

A steering ball seal includes a rigid annular outer case having a radially extending elastomeric sealing member bonded thereto. The sealing member includes a pair of sealing lips which extend radially inwardly of the case. The sealing member further includes an integral annular protective assembly tab which extends axially thereof and which contains a radially protruding retention ridge. The sealing member also includes an integral retention bead radially outwardly of the ridge. The lip and bead cooperate to provide for resilient insertion and removal of an inner case which is retained against the radial body of the sealing member to provide rigidity of the member during operation of the seal. In a preferred form, the inner case is of resilient polyethelene material, and includes a split body construction to facilitate its installation over the steering ball. During assembly of the seal over the steering ball, only the protective assembly tab makes contact with the spherical portion of the steering ball assembly, as the pair of sealing lips are elastically deflected out of contact therewith by the protective assembly tab.
