PROBLEM TO BE SOLVED: To provide an anti-skid brake control device capable of sufficiently recovering a decompression function under an ABS control by recovering brake fluid to a master cylinder with no pump used even if a vehicle is running over a road surface low in a frictional coeficient. SOLUTION: This control device is equipped with an ABS control means capable of forming up a solenoid valve control signal Ca based on the amount of slippage and wheel acceleration wherein vehicle speed is computed based on wheel speed, and the amount of slippage and wheel acceleration are computed based on wheel speed and vehicle speed, a remaining pressure excess condition judging means determining the remaining pressure excess condition of braking pressure Pa under an ABC control, a booster reversal control means forming a control signal CMR turning over the power of a booster 5 in case of a remaining pressure excess condition, and with a power reversing booster valve 9R to be driven by means of a power reversing control signal. This constitution thereby allows the pressure PM of a master cylinder to be quickly and sufficiently reduced by turning over the power of the booster.
