Abstract

Hydraulic brake systems are known wherein, for the purpose of brake control, a counterforce is built up in the booster (60) for actuation of the master brake cylinder which results in unloading the master brake cylinder. What is disadvantageous in the known system is that this counterforce also resets the pedal (pedal piston 3) so that vehement pedal movements will result from the control action. Therefore, our present invention suggests to interpose a transmission device (3, 4, 5, 6, 7) between the pedal and the actuator (booster) enabling to decouple actuator and pedal.
