The present invention provides a vehicle brake system and a control method thereof, capable of operating brakes of a vehicle when an abnormal voltage or current occurs in an inverter. According to the present invention, the system comprises: a vehicle battery; a compressor to generate pneumatic pressure for providing braking of a vehicle; an inverter to receive direct current (DC) provided from the vehicle battery and output alternating current (AC) for operating the compressor; and a vehicle controller to detect whether current or voltage detected from the inverter exceeds a predetermined threshold range during driving of the vehicle, and count the number of detection that the current or voltage exceeds the threshold range. When the counted number of detection is equal to or lower than a predetermined threshold number, the controller reboots the inverter and maintains driving of the vehicle. When the counted number of detection exceeds the predetermined threshold number, the controller stops the driving of the vehicle.
