A brake control apparatus includes a fluid pressure sensor to sense an actual master cylinder pressure, a pump to suck a brake fluid from the master cylinder through a hydraulic circuit connecting the master cylinder to a wheel cylinder and a controller to perform a brake assist control to supply a discharge pressure of the pump to the wheel cylinder in accordance with the sensed actual master cylinder pressure signal. The controller calculates a modified master cylinder pressure by modifying the actual master cylinder pressure in accordance with an operating condition of the pump, calculates a base pressure in accordance with a variation of the modified master cylinder pressure, and calculates a target wheel cylinder pressure in accordance with the base pressure, to control a braking force by controlling an actual wheel cylinder pressure of the wheel cylinder in accordance with the target wheel cylinder pressure.
