A brake control device includes a front-wheel left-right communication passage that allows communication between wheel cylinders for a front-left wheel and a front-right wheel via a front-wheel communication on-off valve; a rear-wheel left-right communication passage that allows communication between wheel cylinders for a rear-left wheel and a rear-right wheel via a rear-wheel communication on-off valve; and a front-rear communication passage that allows communication between a wheel cylinder of either one of the front-left and front-right wheels and a wheel cylinder of either one of the rear-left and rear-right wheels via a front-rear communication on-off valve, wherein the brake control device keeps the front-wheel communication on-off valve, the rear-wheel communication on-off valve, and the front-rear communication on-off valve opened to set a mode to a four-wheel communication mode during a normal brake control. With this, some of linear control valves are deactivated, whereby an operating noise can be reduced.
