Patent ID: 7819231

Claim:
A support assembly for supporting a S cam, the S cam being an intermediary device between a brake actuator and a set of wheel brakes and is generally an elongate metal shank having an S-head at a first end of the shank and a set of splines at the second end of the shank, the S-head having at least one arm for engaging a respective brake shoe, whereby rotation of the S cam in a first direction causes the at least one arm of the S-head to act on the brake shoe to frictionally engage the respective brake shoe with a brake drum, the support assembly comprising: a single elongate bushing rotationally supporting and substantially coextensive along the length of the S cam shank, the bushing extending from proximate the S-head to proximate the splines; and a bushing holder, wherein the single elongate bushing is substantially enclosed within the bushing holder, wherein the bushing is substantially sealed within the bushing holder by a first and second seal member disposed at first and second ends of the bushing respectively, each of the seal members forming a sealing interface with the bushing holder and the S cam shank.
