A hydraulic brake system for motor vehicles with a master cylinder (37), wheel cylinders, a vacuum brake booster (2) and a control module for generating a controlled pneumatic pressure for the vacuum brake booster (2) is proposed. The vacuum brake booster (2) generates a controlled hydraulic pressure. By means of the controlled hydraulic booster pressure, an operating pressure is generated in the master cylinder (37) for actuation of the wheel cylinders of the brake system. This operating pressure acts by way of a passage (35) on a sensing piston (44). The said sensing piston (44) converts the operating pressure into a reaction force, which can be felt on the brake pedal. By means of the invention, an improved reaction force, great flexibility when fitting the brake system in vehicles of different types, a compact construction, a significant reduction of the hysteresis and a simplification of costly, conventional vacuum brake boosters are achieved. <IMAGE>
