Abstract

A damping bushing for a guide pin of a spot-type disc brake is disclosed, having an elastic pleated cup formed with a first end section fixed to a cylindrical body receiving the guide pin, and also formed with a second end section adapted to be assembled to a ring fixed to the guide pin. The ring has a recess which accepts a torus integral with the second end section The torus (74) is formed with an outer large radius of curvature portion and an inner smaller radius of curvature portion which creates a cam shape. The larger radius portion allows a pleat of the second end section to force the torus over a cone shaped ring end and into the ring recess. The torus then is retained by the smaller radius portion engaging a corner of the recess.
