Abstract

A piston structure for use in a brake caliper has a cylindrical base portion having an annular receiving recess and a base mounted spring received therein. A cylindrical brake pad engaging portion has an annular recess formed within its length. A recess is formed within the length of the base portion with an elastomeric o-ring positioned within the recess. A thin layer of metallic material is integrally formed with the remainder of the piston. The thin layer of metallic material is adapted to engage the surface of an adjacent brake pad.
