Abstract
A pin is used to anchor an end of a brake shoe to a boss in a brake spider. The brake shoe has a pair of spaced apart ribs, each of the ribs having an aperture at an end thereof. The pin is a two-piece assembly with first and second elongate members. A first end of each of the elongate members has a trunnion formed on it, and the second end of the elongate members are sized and adapted to telescope one into the other. The trunnions are sized to be received in the rib apertures while an intermediate portion of the pin between the trunnions is sized to be received in the brake spider boss. The first and second trunnions can be compressed towards each other a sufficient distance to permit the trunnions to be disengaged from the rib apertures. A biaser is located inside the pin to urge the first and second elongate members apart from each other, to assist in maintaining the trunnions in the respective rib apertures.
