Patent ID: 6851763

Claim:
Hydraulic brake system, comprising: a brake pressure generator unit which is operable by introducing an actuating force by way of an actuating device, wherein said brake pressure generator includes a first hydraulic chamber having a volume which decreases when the brake pressure generator unit is actuated, out of which a pressure fluid volume is displaced due to the volume decrease and to which wheel brakes are connected by way of a first hydraulic connection, a pump coupled to said first hydraulic chamber for delivering the pressure fluid volume into said set of wheel brakes, wherein said pressure fluid volume is displaced out of the first hydraulic chamber due to the volume decrease, and wherein the first hydraulic chamber includes an elastic device disposed therein, wherein said elastic device defines a force versus travel characteristics in the actuating device when said actuating force is introduced, wherein the brake pressure generator unit includes a tandem master brake cylinder with two hydraulic master brake cylinder chambers, one master brake cylinder chamber thereof being connected by way of a hydraulic line to a second piston chamber in which the elastic device can be acted upon by pressure force by means of a separating piston.
