Abstract
A seal for use on a disc brake piston/caliper assembly which seals the piston and also functions as a piston-return spring. The seal has a seal-retaining portion, a sealing lip portion, and a radially extending flex portion therebetween for retracting the piston by an amount equal to the flex portion retraction, thus automatically adjusting the piston position to compensate for normal pad wear. The seal can also include a locking flange and a separate pressure sealing lip to allow the seal to function without the previously required separate lathe cut sealing ring.
