ABSTRACT:
In a brake apparatus for a hydraulic two-circuit brake installation of a road vehicle with static brake circuits, an outlet pressure space is provided for one of these brake circuits in which the brake pressure that is coupled into a static brake circuit of the vehicle, is adapted to be built up by the displacement in the same direction of a master cylinder piston which is also displaceable by the pedal force alone, and of a servo piston which is displaceable only when the brake force servo unit is intact. The servo piston displaceable only with an intact brake force servo unit includes an annular piston which by pressure actuation of its actuating surface with the outlet pressure of a brake valve of the brake force servo unit, is urged into unilateral abutment with an entrainment flange of a plunger piston extending through the annular piston in the axial direction, which plunger piston, in its turn, is coupled for movement with a force-transmitting element, by way of which also the component of the actuating force resulting from the pedal actuation and acting on the master cylinder piston in the sense of a brake pressure build up displacement is introduced into the same.
