The invention relates to an actuator subassembly for a vehicle brake with a drive, which is connected to an input side of a lever arrangement, wherein an output side of the lever arrangement is adapted to operate at least one friction element of the vehicle brake. If a vehicle brake of this kind is used as a parking brake, static preloading forces occur at the friction element. In order that these forces may still be taken up within the actuator subassembly, it is proposed that the lever arrangement be changed over from a service brake region, in which it is self-releasing, beyond its force reversal point into a parking brake position, in which it is self-locking. Various operating possibilities for an actuator subassembly of this kind and the use thereof in a vehicle brake are described.
