ABSTRACT:
In a vehicle brake having a brake piston accommodated in a housing, a blocking device for securing the brake piston inside the housing and an actuating device for controlling the blocking device, it is provided that the brake piston together with the housing delimits a fluid chamber, which is chargeable with hydraulic fluid, so that the brake piston for actuating the vehicle brake is displaceable hydraulically inside the housing along a piston longitudinal axis, that moreover the blocking device comprises a ramp arrangement and a blocking element that is displaceable relative to the housing, and that by means of the actuating device the blocking element in interaction with the ramp arrangement for securing the brake piston inside the housing is displaceable and connectable to the brake piston. In this vehicle brake, it is further provided that the actuating device comprises a motor drive, which is drive-connected to the ramp arrangement, wherein the blocking element upon activation of the motor drive is displaced to secure and release the brake piston inside the housing.
