1. An apparatus for controlling an Anti-lock Brake System (ABS) of an Electronic Stability Control (ESC) integrated brake system, the apparatus comprising:
a main master cylinder generating hydraulic brake pressure through a piston that is moved forward/backward by an actuator that is operated when a vehicle is in a braking status; and
a controller configured to:
determine whether a direction change condition according to a control state of wheel pressure is satisfied when a brake mode of the vehicle is an ABS mode and the piston has reached a predetermined direction change position for forward/backward movement direction change, and
perform forward/backward movement direction change of the piston by controlling a driving current that is applied to the actuator upon determining that the direction change condition according to the control state of wheel pressure is satisfied,
wherein the controller determines whether the direction change condition is satisfied by checking open/close states of inlet valves that connect/disconnect hydraulic brake pressure that is supplied to each wheel cylinder of the vehicle.
