Abstract: A brake device includes: a first pressurizing unit configured to increase a WC pressure by supplying brake fluid into wheel cylinders provided in wheels RL and RR; a second pressurizing unit connected to a reservoir tank via a fourth flow passage and configured to increase the WC pressure by supplying the brake fluid taken in from the reservoir tank into the wheel cylinders; and a brake control unit configured to control at least one of the first pressurizing unit and the second pressurizing unit based on a target WC pressure. The brake control unit is configured to, when the WC pressure is to be increased by operating the second pressurizing unit, execute an auxiliary brake control in which the first pressurizing unit is operated to assist the second pressurizing unit to increase the WC pressure.
