A vehicle brake booster system includes a reservoir, a pump, and a brake booster. The brake booster includes an input member adapted to receive a manual braking input force and an output member adapted to apply a braking output force to a master cylinder. A supply line couples the pump to the brake booster, and a return line couples an outlet of the brake booster to the reservoir. A flow of hydraulic fluid pumped to the brake booster provides a boost factor by which the braking output force exceeds the braking input force. The brake booster is hydraulically lockable by a first valve in the supply line and a second valve in the return line such that when the first and second valves are closed, a quantity of hydraulic fluid is trapped within the brake booster to maintain operation of the brake booster without continued operation of the pump.
