Linear actuator 10 for a hydraulic braking system, comprising an electric motor with a stator 6 and a rotor 2, a motor housing 7, and a nut 1 and screw 3 which are rotatable with respect to each other. The nut 1 is fixed to the rotor 2 and the screw 3 is fixed to the piston (20; fig. 4) which is axially moveable into a hydraulic pressure chamber (21; fig. 4). The axial length of the nut 1 may be longer than the axial length of the screw, e.g. three times longer. The nut and screw may form a ball screw drive, with ball roller bearings. The screw/spindle may include a rod with longitudinal channels (see figure 2) to prevent rotational movement of the screw relative to the piston. There may be a joint 14 to prevent axial deviation of the screw. There may be a rubber plug 16 between the screw and the housing for zero point protection.
