Abstract:
A disc brake in which a friction pad assembly is adapted to be applied to one face of a rotatable disc by brake applying means housed in a housing mounted on a selectively stationary part adjacent of the disc, the friction pad assembly comprising a backing plate and a pad of friction material supported by the backing plate, and in which the friction pad assembly is guided for movement towards and away from the disc on drag taking surfaces which take drag on the friction pad assembly when the brake is applied, wherein said pad of friction material is provided at its radially most inner and outer edges of its leading edge with circumferentially projecting protrusions the sum of the radial thickness of the protrusions being small in comparison with the total radial thickness of the pad, and the arrangement being such that in the event of tilting of the pad assembly with respect of the disc when the brake is in the off position, contact between the protrusions and the disc presents contact between the remainder of the surface area of the pad and the disc.
