1. A system for brake inspection of vehicle for checking a brake performance of the vehicle in which brake fluid is injected in a vehicle factory, comprising:
a communication unit connecting the vehicle entered through a conveyor and a diagnostic communication;
a specification determination unit that collects specification information of the vehicle and determines whether to apply an electronic stability control (ESC) device;
an ESC driver that transmits a control signal through the diagnostic communication to the vehicle to which the ESC device is applied, to generate braking hydraulic pressure according to forced driving of the ESC device; and
an inspector consisting of a control unit that determines that an ESC pressure value measured by forced driving of the ESC device exceeds a set reference value, and determines that a brake pressure is normal (OK), and determines that the ESC pressure is abnormal (NG);
wherein the control unit is configured to repeatedly generate a brake braking hydraulic pressure of the ESC device a predetermined number of times through the ESC driver to deliver a brake fluid to a caliper before the control unit determine the ESC pressure value measured exceeds the set reference value.
