Abstract: A pad spring that fits on a brake carrier of a disc brake resiliently restrains one end of a disc brake pad in the carrier from movement in a radial direction. The pad spring has an abutment surface that supports one end of the pad and resiliently restraining movement thereof. The abutment surface is harder or softer than the backplate of the brake pad contacting the abutment surface to provide a wearing surface. The pad spring is configured to permit the brake disc pad to be mounted to the brake carrier in a radially inward direction while the disc brake in an assembled state.

Abstract: In a suspension strut a piston-rod works through an elastomeric seal at the inner end of a tubular extension which depends from an end plug closing the upper end of cylinder. The seal comprises a collar which encircles the free end of the extension and is provided with a depending, contiguous, radial sealing flange which overlies the free end of the extension. The flange may be encircled by a retaining ring which enhances the grip of the flange against the rod, and the collar may be stiffened by a metal tubular former embedded in the material of the collar.
