PROBLEM TO BE SOLVED: To provide a brake control device conducting antiskid control and the drive slip control of a rear wheel, capable of interlocking front and rear wheels and capable of controlling them or applying a normal brake action by providing feed solenoid selector valves and discharge solenoid selector valves for the front and rear wheels respectively and two gang control solenoid selector valves for the front and rear wheels. SOLUTION: When only one of front and rear master cylinders 1, 2 is operated, a first gang control solenoid selector valve 6b or 6a connected to the other is closed, a second gang control solenoid selector valve 19b or 19a is opened, and a hydraulic pump 11 is driven to apply a brake to both wheels. At the time of brake slip control, the brake hydraulic pressures of front and rear wheels are controlled by the feed solenoid selector valves 8a, 8b and discharge solenoid selector valves 9a, 9b of the front and rear wheels. At the time of the drive slip control of the rear wheel, the first gang control solenoid selector valve 6b for the rear wheel is closed, the second gang control solenoid selector valve 19b for the rear wheel is opened, and the hydraulic pump 11 is driven to apply a brake to both wheels.
