PURPOSE: A booster of braking hydraulic pressure of a braking device for a vehicle and its method are provided to compensate braking force by raising oil pressure of a wheel cylinder. CONSTITUTION: An auxiliary air tank(70) stores compressed air from an air compressor(10) by connecting with the air compressor and connecting between a brake valve(30) and an air master(40). A safety valve(80) controls the air flow from the air compressor by installing between the air compressor and the auxiliary air tank. A magnetic valve(300) is turned on/off by installing between the auxiliary air tank, the brake valve and the air master and synchronizing with a control signal. An electronic control device(200) outputs the control signal when an ABS(Anti-lock Brake System) is not operated by receiving the speed, the oil pressure, the operated state of a brake pedal and the reduced speed of a vehicle and controlling through a set program. The stable braking force is offered by raising the oil pressure of a wheel cylinder.
