Abstract
A bushing assembly (30) for a caliper disk brake includes a pair of bushings (32) opposingly disposed on a common centerline (34) in a caliper brake bolt bore (56). Each bushing (32) has a cylindrical body section (40) and a flange (50) extending from the body section (40). The body section (40) has a plurality of ribs (52) extending radially inward from the inner surface (54) of the body section (40) and a circumferential groove (60) in the outer surface (62) of the body section (40). The groove (60) is configured to seat a retainer ring (36) that prevents the bushing (32) from being ejected from the bolt bore (56) in which the bushings (32) are installed. The bushing assembly (30) prevents the caliper arm (16) from binding to the caliper bolts (18) when corrosion builds around the caliper bolt (18) by providing a space (72) between the second ends (44) of the bushings (32).
