The one-way two-stage pressure boosting brake pump comprises a valve body, an oil outlet connector is arranged at the front end of the valve body, an oil outlet is formed in the oil outlet connector, and the front end of the oil outlet is connected with a brake piston; an oil inlet connector and a backpressure one-way valve are installed on the valve body, and a piston sleeve is arranged in the valve body. A Y oil way is formed; the front section of the brake push rod is a small-diameter section, and the rear section is a large-diameter section; a spring containing hole and an X oil way are formed in the small-diameter section, and a liquid filling one-way valve is arranged between the spring containing hole and the X oil way. A sealing face with a hole is arranged in the oil inlet connector, a check valve is arranged below the sealing face and sleeved with a check valve reset spring, the liquid inlet end of the check valve faces the sealing face, and when the check valve reset spring is in a reset state, the check valve is in contact with the sealing face to form sealing. The problem that an existing large-displacement brake pump on the market is insufficient in pressure is solved, the structure is simple, and the price is low.
