Abstract: The brake system includes a pedal, a pedal simulator, and a brake pedal unit. The brake pedal unit includes an input piston connected to the brake pedal for operating the pedal simulator during a normal braking mode. The brake pedal unit further includes first and second output pistons actuated by the input piston during a manual push through mode such that the first output piston generates brake actuating pressure at a first output of the brake pedal unit, and the second output piston generates actuating pressure at a second output of the brake pedal unit. The brake system further includes a hydraulic pressure source for supplying fluid at a controlled boost pressure, and a hydraulic control unit adapted to be hydraulically connected to the brake pedal unit and the hydraulic pressure source.

Abstract: A master cylinder for a vehicle hydraulic brake system has a housing with a bore formed therein, which is open at one end and in which a first pressure piston and a second pressure piston are guided sealingly and displaceably along an axis. Acting counter to an actuating direction upon the first pressure piston is a restrained first restoring spring and upon the second pressure piston a second restoring spring. In order, in a transportation or disassembly state of the master cylinder, to prevent the first pressure piston from being pressed excessively out of the bore, the second pressure piston is supported by means of a stop component counter to the actuating direction positively in the housing of the master cylinder.

Abstract: A master cylinder (10) for a vehicle hydraulic brake system has a housing (12) with a bore (14) formed therein, which is open at one end and in which a first pressure piston (16) and a second pressure piston (18) are guided sealingly and displaceably along an axis (A). Acting counter to an actuating direction (X) upon the first pressure piston (16) is a restrained first restoring spring (34) and upon the second pressure piston (18) a second restoring spring (52). In order, in a transportation or disassembly state of the master cylinder (10), to prevent the first pressure piston (16) from being pressed excessively out of the bore (14), the second pressure piston (18) is supported by means of a stop component (66) counter to the actuating direction (X) positively in the housing (12) of the master cylinder (10).
