A disc brake comprising a caliper straddling a rotary disc and carrying a pair of friction pads is disclosed. The friction pads are slidably received and anchor on guides defined by the circumferentially spaced edges of a radial aperture in the caliper. The caliper is slidably mounted on a fixed support member and carries a fluid pressure motor comprising a piston received in a cylinder and capable to occupy an idle position, an operating position closer to the disc than the idle position and a retracted position further from the disc than the idle position. Slots are provided in the guides to permit removal of the pads when the piston occupies its retracted position, and a detachable resilient clip is normally mounted on an axially extending portion of the cylinder between said cylinder and the adjacent pad to prevent the latter from moving back opposite the corresponding slot whatever the position occupied by the piston.
