Abstract
A master cylinder for a vehicle hydraulic brake system having slip control is disclosed including a master cylinder piston in a bore defining a prechamber connected to an auxiliary fluid energy supply and a working chamber. A tube like projection on the master cylinder piston extends through a one-way sleeve seal into the working chamber. Auxiliary fluid is dynamically supplied from the prechamber past the one way sleeve seal into the working chamber and to the wheel brakes during slip control.
