Abstract
A brake control apparatus () includes: a hydraulic pressure source () that regulates pressure of hydraulic fluid in accordance with a brake operation input (); a wheel cylinder () that applies braking force to a wheel () in response to a supply of the hydraulic fluid to the wheel cylinder (); a hydraulic pressure booster mechanism () that amplifies the brake operation input by using the hydraulic pressure source (), and outputs the amplified brake operation input; a hydraulic fluid supply path () through which the hydraulic fluid is supplied from the hydraulic pressure source () to the wheel cylinder (); and a controller () that shuts off (valve) a flow of the hydraulic fluid-through the hydraulic fluid supply path (), if a malfunction due to hydraulic fluid leakage is detected in the hydraulic fluid supply path () during a brake control mode in which the hydraulic fluid is supplied to the wheel cylinder () through the hydraulic fluid supply path ().
