A disc brake includes a rotor mounted for rotation with a member to be braked and a caliper slidably mounted on a fixed torque member. The caliper includes a housing defining a bore therewithin, and a piston is slidably mounted in the bore to urge friction elements disposed on opposite sides of the rotor into braking engagement with the latter when pressurized fluid is admitted into the bore during a brake application. A parking actuator is provided which includes a lever mounted within the caliper housing for rotation about an axis extending generally parallel to the axis of the rotor and for movement relative to the caliper along this axis. An elongated member interconnects the lever with the piston. Force transmitting elements are disposed between the lever and the end of the housing, so that when the lever is rotated, the force transmitting elements urge the latter toward the rotor. This axial movement is transmitted to the piston by the elongated member, to urge the piston toward the rotor, effecting a brake application.
