An actuating mechanism, particularly for a disc brake caliper, including a screw actuator having a screw 40 and a nut 18 threadably coupled together, an electric drive for driving one of the screw 40 and the nut 18 axially relative to the other and including a stator 20 and a rotor 22 , a sleeve assembly including a generally cylindrical sleeve 25 interposed between the rotor 22 and the nut 18 and supporting the rotor 22 for rotation relative to the sleeve 25 . The rotor 22 is connected to one of the screw 40 or the nut 18 for rotating the screw 40 or the nut 18 . The screw actuator being at least partly mounted within the sleeve 25 and being arranged to bear against a portion of the sleeve assembly to transmit axial thrust to the sleeve assembly, and the sleeve assembly cooperating with an abutment to transmit the axial thrust to the abutment.
