PCT No. PCT/EP90/00064 Sec. 371 Date Oct. 9, 1990 Sec. 102(e) Date Oct. 9, 1990 PCT Filed Jan. 12, 1990 PCT Pub. No. WO90/09534 PCT Pub. Date Aug. 23, 1990.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.
