Abstract

A brake control apparatus includes wheel cylinders which apply braking force to wheels when supplied with hydraulic fluid; a wheel cylinder pressure control system that controls a wheel cylinder pressure independently of a brake operating member operation; a manual hydraulic pressure source that includes first and second hydraulic pressure sources that pressurize the hydraulic fluid; a hydraulic fluid supply path that connects the manual hydraulic pressure source to the wheel cylinders; and a controller. Communication through the hydraulic fluid supply path is interrupted when the wheel cylinder pressure control system controls the wheel cylinder pressure, and the communication is permitted when the wheel cylinder pressure deviates from a target pressure. The controller executes control so that the hydraulic fluid from the first hydraulic pressure source starts to be supplied after the hydraulic fluid from the second hydraulic pressure source starts to be supplied.
