A brake-pressure control device for a motor-vehicle braking system, with an electric motor, the rotatory motion of which is transformed by a ball screw drive into a translatory motion of a piston in a working cylinder, in order to be able to build up a defined braking pressure in a wheel brake independently of actuation of a master brake cylinder. An aspect provides that the ball screw drive is provided with a friction slip coupling engaged over a profiled tube which is fixedly connected to a nut of the ball screw drive and to which the piston is fixed.
