In a disc brake of the kind in which friction pad assemblies are urged into engagement with opposite faces of a rotatable disc by operation of an hydraulic actuator which applies one friction pad assembly directly to one face of the disc and other friction pad assembly to the opposite face of the disc through a yoke guided to slide relative to a stationary member mounted adjacent to the disc, the yoke comprises a one piece assembly adapted to fit over the stationary member and a portion of the periphery of the disc. The yoke is provided with a pair of spaced flat parallel guiding surfaces of substantial radial depth for direct operative engagement with complementary flat guiding surfaces on opposite sides of the stationary member, and the guiding surfaces on the yoke, at least at one pair of corresponding ends, lead into opposed bearing surfaces for engagement with complementary shoulders on the stationary member.
