A motor vehicle brake, in particular a combined hydraulically and electromechanically actuatable motor vehicle brake, with an actuator assembly comprising: a housing, an actuator which can be moved relative to the housing for hydraulically or electromechanically moving a brake lining, a motor drive, a movement mechanism which is arranged between the motor drive and the movable actuator, a gear arrangement which is paired with the movement mechanism, and a separate self-locking device which is designed to block the movement mechanism when necessary, wherein the movement mechanism has a ball screw drive with a rotatable spindle and a nut which can be moved in the housing in a linear manner. The nut can be moved within the housing in order to move the actuator by rotating the spindle, and the gear arrangement has at least two gear stages. In the motor vehicle brake, the self-locking device is arranged in or on the gear arrangement such that at least two gear stages are arranged between the ball screw drive and the self-locking device.
