Abstract: PROBLEM TO BE SOLVED: To provide a brake boosting master cylinder providing brake characteristics setting a vehicle decelerating speed (brake force) and a pedal stroke relative to the pedal treading force to approximately same irrelevant to the operation/non-operation of other brake systems such as a regenerative brake system. SOLUTION: The delivery pressure of a pump 45 is regulated by a pressure regulating valve 47 according to a pedal treading force or a pedal stroke and fed to a pump delivery pressure chamber 36. Generally, the pump delivery pressure is largely regulated in operating the brake so as to have large MCY pressure. In this case, the stroke of the primary piston 10 is large, while the stroke of an input shaft 41 is small. The delivery pressure is regulated small in operating a regenerative cooperation brake so as to provide a small MCY pressure so that the brake force by the MCY pressure becomes smaller by the regenerative cooperation brake force. Though the stroke of the piston 10 is small, the MCY pressure is small so that the stroke of the input shaft 41 is almost same as the general brake operation time.
