The friction pad for a disc brake comprises a backing plate having a major portion defined by curved longitudinal edges of different radii of curvature joined by spaced lateral edges. Friction material is secured to one side of the major portion of the backing plate and a supporting portion of the backing plate. - A tab has a head joined to the major portion of the backing plate by a neck portion of less circumferential length then the head portion. A surface joins the head portion to the neck portion and forms a shoulder at each end of the tab. The shoulder at each end of the tab is non-symmetrical relative to the major portion of the backing plate. Each of the shoulders may be slidably received on only one of a pair of corresponding non-symmetrical edges of a supporting member. (7/8) EPAB- EP-139890 B A friction pad (34) for a disc brake (10) comprising a backing plate (35) having a major portion (70) defined by arcuate longitudinal edges (73, 74) of different radii of curvature joined by spaced lateral edges (75,76), friction material (39) secured to one side of said major portion (70) of said backing plate (35) and a supporting portoin of said backing plate (35) comprising a tab (67) having a head portion (68) joined to said major portion (70) of said backing plate (35) by a neck portion (78) of less circumferential length than said head portion (68), a surface joining said head portion (68) to said neck portion (78) and forming a shoulder (28,84) at each end of said tab (67), characterised in that said shoulder (82, 84) at each end of said tab (67) is non-symmetrical relative to the major portion (70) of said backing plate (35) whereby each of said shoulders (82,84) may be slidably received on only one of a pair of corresponding non-symmetrical edges of a supporting member (54,58).

Friction material is secured to one side of the major portion of the backing plate and a supporting portion of the backing plate comprises a single T-shaped tab having a head portion joined to the major portion of said backing plate by a neck portion of less circumferential length then the head portion. - A surface joins the head-portion to the neck portion and forms a shoulder at each end of the tab, the shoulders at each end of the tab are non-symmetrical relative to the major portion of said backing plate. Each of the shoulders may be slidably received on only one of a pair of corresponding non-symmetrical edges of a supporting member. (8pp)
