A composite plunger force feedback type hydraulic pressurizing brake pump comprises a brake pump shell combination and a composite plunger combination, the composite plunger combination is arranged in a cavity of the brake pump shell combination in a sliding mode, and the cavity of the brake pump shell combination is divided into an oil inlet cavity, an oil return cavity and a pressurizing cavity. The pressure difference between the oil inlet cavity and the oil return cavity is increased through the pressurizing cavity and then transmitted to the brake, and a tractor or other vehicles are braked. The composite plunger combination comprises a composite plunger and a force feedback plunger, the force feedback plunger is arranged in the composite plunger in a sliding mode, and the magnitude of hydraulic oil flowing damping between an oil inlet cavity and an oil return cavity is controlled or oil way connection between the oil inlet cavity and the oil return cavity is cut off through the sliding stroke of the force feedback plunger; according to the brake pump, the stroke of the feedback control plunger can be controlled through the feedback force of the force feedback plunger, deceleration braking of a tractor or other motor vehicles is achieved, the feedback control plunger can be directly made to move in place, and emergency braking of the tractor or other vehicles is achieved.
