Caliper mounting suspension

摘要

Resilient rings are fitted between the caliper and the mounting bolts to provide free caliper movement and permanent corrosion protection. One resilient ring has internal lands contracting the mounting bolt and positioned within the caliper. The lands act as a rubber spring with memory which retracts the caliper, reducing brake drag. Reduced rubber contact area with the mounting bolt reduces adhesion of the rubber to the bolt. The resilient ring may alternatively have external lands which grip or slip on the caliper housing instead of the mounting bolt. A seal may be provided as an extension of the one resilient ring to protect the mounting bolt surface.
