ABSTRACT:
A brake control apparatus includes: at least one wheel cylinder that applies braking force to a vehicle wheel in response to supply of hydraulic fluid thereto; a manual hydraulic pressure source that pressurizes hydraulic fluid in accordance with brake operation by a driver; a cut valve which is arranged in a hydraulic fluid delivery path between the manual hydraulic pressure source and the wheel cylinder, and to which force is applied in such a direction that the cut valve is closed when the wheel cylinder is higher in hydraulic pressure than the manual hydraulic pressure source; and a controller that controls a discharge path, through which the hydraulic fluid is discharged from the wheel cylinder and which differs from the hydraulic fluid delivery path, so that discharge of the hydraulic fluid from the wheel cylinder through the discharge path starts in response to release of the brake.
