Date Sep. 26, 1996A boosted braking device having a master cylinder and a pneumatic booster wherein the force for actuating the master cylinder is derived from a combination of an input force and a boost force of the booster. A main hydraulic piston of the master cylinder has a holler cylinder for receiving the input force. A secondary hydraulic piston located within the holler cylinder of the main hydraulic piston receives a hydraulic reaction force to impart an increasing braking force corresponding to an input force applied over an entire travel of a brake pedal.
