PURPOSE: An air brake system for a vehicle is provided to discharge air from an oil line conveniently in a large air brake installation vehicle, and to reduce manpower by connecting extension pipes of the magnetic valve to a connector. CONSTITUTION: An air brake system of a vehicle is composed of a compressed air tank(10) storing compressed air; a brake pedal(20); a relay valve(30); an air booster(40); plural air lines(11,21,31,41); a bypass line connected to the compressed air tank and the relay valve; a wheel cylinder(51) connected to the air booster through the oil line; a drum(52); a brake shoe(53); a double check valve installed in the relay valve by connecting an inlet(61) to the brake pedal; a magnetic valve(70) connected between the compressed air tank and an inlet(62) of the double check valve; and a switch cable(80) connected to the magnetic valve and a battery(81). Air is conveniently discharged from the oil line of the air brake system.
