A brake control system (20) includes at least one wheel cylinder (23) that receives the work fluid to apply a braking force to a corresponding vehicle wheel, a wheel cylinder pressure control system (30, 40) that controls the control pressure applied to the at least one wheel cylinder 23 by controlling the supply of the work fluid thereto, a first abnormality determination unit (90, 92) that determines whether an abnormality in the wheel cylinder pressure control system (30, 40) based on an initial response characteristic of the control pressure after a braking request within a predetermined abnormality determination time, and a second abnormality determination unit (92) that determines whether the abnormality in the wheel cylinder pressure system is present based on a comparison between the control pressure and a reference pressure based on which the determination is made with respect to the abnormality within a predetermined second abnormality determination time that is set to expire before expiration of the first abnormality determination time..
