A wear insert is provided for receiving trunnions on the ends of pieces
used in affixing brake shoes to a brake shoe assembly. A vehicle brake
shoe assembly has brake shoes which may be urged outwardly against a brake
drum when a S-cam is rotated. The brake shoe has an arcuate brake table on
which friction liners are installed. A brake web, comprising a pair of
brake web elements, extends inwardly from the brake table toward the
center of radius of the arcuate brake table. Each of these spaced apart
web elements has a first and a second end, and each of the ends is
provided with a trunnion receiving slot. The trunnion receiving slots at
one end receive the trunnions of an anchor pin, and the trunnion receiving
slots at the other end receive the trunnions of a cam follower. The wear
insert is removably seated in at least one of the trunnion slots to be
interposed between the slot and the trunnion. When a hardened spring steel
is used for the wear insert, the insert will reduce the wear upon the
slot, thereby extending the life of the brake shoe. The preferred wear
insert is a U-shaped sleeve with radial lips at the ends to prevent axial
movement of the sleeve in the trunnion receiving slot.
