Shimano no longer stocks the arm spring sleeve that they used on BR-5500 through BR-6700 series caliper brakes. This is a plastic bushing that keeps the end of the arm spring from cold-welding to (or gouging into) one caliper arm. Mine are wearing out. Has anyone on the forum successfully used a replacement material for these, and if so, what did you use?
