Abstract: The invention relates to an actuating device for a motor vehicle brake, comprising the following components: an actuating device, in particular in the form of a brake pedal, a pressure supply device (11), in particular a reciprocating pump or double-acting reciprocating pump, driven by an electric motor drive (M), a piston-cylinder unit (main cylinder) (10) that can be actuated by means of the actuating device, that is connected hydraulically with a hydraulic fluid reservoir (BFR) and that forms at least two pressure chambers that are connected with hydraulic brake circuits, a valve assembly (HCU) with valves for adjusting brake pressures in a wheel-specific manner and for disconnecting or connecting the wheel brakes from or to the pressure supply device (11) and the piston-cylinder unit (10), an electronic control unit (ECU), at least one sensor device, having at least one sensor or evaluation element (3, 4, 5, 24, 24a) and a sensor target (5a, 23, 23a), preferably based on an electromagnetic principle, for sensing a movement of a device component. According to the invention,at least one sensor or evaluation element (3, 4, 5, 24, 24a) of the sensor device is arranged on or in the electronic control unit (ECU), in particular on a system printed circuit board (PCB) of the control unit (25), and that a movement of the device component (10; 45; 46; 48) is transmitted to the electronic control unit (ECU) (25) via a sensor actuating device, in particular via a mechanical actuating mechanism (17, 18, 19) or via a sensor target (5a, 23, 23a) connected with the device component and magnetic flux-conducting components (43, 43, a, 43b) based on ferromagnetic materials.
