Abstract: The application relates to a brake system for a vehicle, comprising a brake piston connectable to a brake pad and configured for performing a braking motion to press the brake pad against a friction surface, a hydraulic brake unit configured for hydraulic actuation of the braking motion, an electro-mechanical parking brake actuator configured for actuating the braking motion comprising a spindle rotatable by an electric motor, and a nut such that a rotational motion of the spindle leads to a translational motion of the nut, wherein the nut is coupled with the brake piston such that a translational motion of the nut toward the brake piston actuates the braking motion of the brake piston, wherein the brake system further comprises an elastic member coupling the brake piston with the nut, configured to drive a motion of the brake piston in a direction opposite the direction of the braking motion.
