PROBLEM TO BE SOLVED: To provide a brake control device suppressing the physical constitution of the device small and improving the layout property.SOLUTION: A small-diameter piston 10 for receiving the braking operations of a driver is inserted through a large-diameter piston 10 which partitions a master cylinder MC into a pressure chamber 1 and a back pressure chamber 2. The back pressure chamber 2 and wheel cylinders WCRL, WCRR at the rear wheel side are connected, and the pressure chamber 1 and wheel cylinders WCFL, WCFR at the front wheel side are inserted. Pumps 301, 302 supplying pressure to the back pressure chamber 2 are driven so that the pressure of the back pressure chamber 2 be a back pressure chamber target liquid pressure corresponding to a brake pedal stroke. |
