ABSTRACT:
A braking apparatus (28) includes a housing (38). The housing (38) includes therein: a master cylinder section (40) for supplying pressurized fluid to the brakes (24) of an automotive vehicle (10) to effect a brake application, a hydraulic booster section (42) for assisting the master cylinder section (40) to effect a brake application, a fluid pumping section (44) driven by an electric motor, for supplying pressurized fluid to the hydraulic booster section (42), and a reservoir section (46) supplying a single fluid to the sections 40, 42, and 44. The electric motor driving the fluid pumping section (44) receives energy from the vehicle (10) only in response to a need for braking. The brake booster (28) includes a fluid pressure accumulator (147) providing pressurized fluid to the booster section (42) during a brake application. The accumulator (147) also provides for power-assisted braking in the event of a failure of the motor-driven pumping section (44).
