The invention relates to a motor vehicle brake, in particular a motor vehicle brake that can be actuated in a combined hydraulic and electromechanical manner, having an actuator assembly (10) comprising: a housing (12), an actuating element (14) that can be displaced relative to the housing (12) along a longitudinal axis (A) for the hydraulic or electromechanical displacement of a brake lining, a motor drive (22), and a displacement mechanism, arranged between the motor drive (22) and the displaceable actuating element (14), for displacing the actuating element (14). In order to achieve a rapid feed movement, the displacement mechanism according to the invention has a multi-stage spindle-nut arrangement (31) comprising a first spindle-nut pair having a first thread pitch and a second spindle-nut pair having a second thread pitch, wherein the first thread pitch is greater than the second thread pitch, wherein, during an electromechanical actuation of the motor vehicle brake, the first spindle-nut pair is active in a first actuating phase and the second spindle-nut pair is active in a second actuating phase.
