PROBLEM TO BE SOLVED: To provide a brake fluid pressure control system for a vehicle capable of adjusting brake fluid pressure applied to a wheel brake by simple control. SOLUTION: A brake fluid pressure control system for a vehicle is equipped for each system of X piping with a cut valve 6 which is a linear solenoid valve provided to a first fluid pressure passage, a pump 4 which can pressurize a wheel brake side rather than the cut valve 6 in the first fluid pressure passage and a control valve means V provided to a second fluid pressure passage, and includes a target fluid pressure setting part 21 for setting target fluid pressure of each wheel brake and a valve driving part 23 for controlling to drive the cut valve 6 and control valve means V on the basis of target fluid pressure. The valve driving part 23 controls a wheel brake having higher target liquid pressure through the driving of the cut valve 6 only and a wheel brake having lower target liquid pressure through the driving of the corresponding control valve means V by controlling to drive for each system the cut valve 6 taking a higher target fluid pressure of respective wheel brakes as the target fluid pressure of the first liquid passage.
