ABSTRACT:
A hydraulic dual-circuit tandem main brake cylinder which includes at least one closed brake circuit (I) having a brake piston. This brake piston is actuated by means of the pressure fed into a pressure chamber by means of a brake control valve with a travel simulator spring. Adjoining this pressure chamber is also an auxiliary piston device, which comprises an auxiliary piston and a tappet passing therethrough and connected indirectly with the brake pedal. A highly progressive spring is fastened between the auxiliary piston and the tappet; this spring predominantly determines the pedal characteristic.
