To improve brake force in front and rear combined brake control, a brake control device includes a front wheel brake caliper having at least two front wheel cylinders, and a rear wheel brake caliper having a rear wheel cylinder. A front wheel brake conduit is disposed between a front wheel master cylinder and one of the front wheel cylinders, and a rear wheel brake conduit is disposed between a rear wheel master cylinder and the rear wheel cylinder. A pressure amplification conduit branches from a first position in the rear wheel brake conduit and merges with the rear wheel brake conduit at a second position downstream of the first position. A combined brake conduit branches from a third position in the rear wheel brake conduit positioned downstream of the first position and is coupled to the other of the front wheel cylinders. A first switch control valve is disposed between the first position and the third position in the rear wheel brake conduit. A second switch control valve in disposed in the pressure amplification conduit. A hydraulic pump is provided in the pressure amplification conduit, and a controlling device is provided that controls the opening and closing of the valves and actuation of the hydraulic pump.
