The invention provides a hydraulic booster and brake master cylinder assembly which comprises a brake master cylinder and further comprises a hydraulic booster, the hydraulic booster comprises a pump body provided with an oil duct, and the pump body is connected with a pump cover provided with a groove and a sealing piece through a bolt to form a boosting cavity; and an oil inlet and two oil outlets are formed in the pump body, a hole in the end of the booster piston is a three-stage stepped hole, the first-stage stepped hole is used for limiting an output push rod, the second-stage stepped hole is used for limiting an output push rod check ring and guiding the output push rod, and the third-stage stepped hole serves as a spring seat and is used for limiting a booster piston return spring. According to the hydraulic booster and brake master cylinder assembly, the oil inlet of the booster pump body penetrates through the sliding valve hole to be communicated with the plunger hole, the plunger hole is directly communicated with the energy accumulator oil way, machining of a technological hole and using of a technological plug are omitted, the machining efficiency is improved, and the manufacturing cost is reduced.
