Brake control apparatus and brake control method

A brake control apparatus (20) includes: a hydraulic pressure source (30) that regulates pressure of hydraulic fluid in accordance with a brake operation input (24,25); a wheel cylinder (23) that applies braking force to a wheel (22) in response to a supply of the hydraulic fluid to the wheel cylinder 823); a hydraulic pressure booster mechanism (31) that amplifies the brake operation input by using the hydraulic pressure source (30), and outputs the amplified brake operation input; a hydraulic fluid supply path (63) through which the hydraulic fluid is supplied from the hydraulic pressure source (30) to the wheel cylinder (23); and a controller (70) that shuts off (valve 66) a flow of the hydraulic fluid- through the hydraulic fluid supply path (63), if a malfunction due to hydraulic fluid leakage is detected in the hydraulic fluid supply path (63) during a brake control mode in which the hydraulic fluid is supplied to the wheel cylinder (23) through the hydraulic fluid supply path (63).
