PCT No. PCT/EP89/01307 Sec. 371 Date Jun. 29, 1990 Sec. 102(e) Date Jun. 29, 1990 PCT Filed Nov. 1, 1990 PCT Pub. No. WO90/05081 PCT Pub. Date May 17, 1990.A brake system is provided which includes a restoring unit by which a restoring force can be applied to the pedal. Since the pedal, at the same time, actuates a control valve 9 determining the booster force, during a restoring operation, the booster force also is reduced. The wall 40 accepting the restoring forces advantageously can be located in the booster housing 5 between the master cylinder 1 and the booster wall 6. Since the wall 40 covers relatively small distances only relative to the booster wall 6, the overall length of the booster housing 5 is not significantly increased.
