PROBLEM TO BE SOLVED: To provide a brake hydraulic control device for a vehicle for contributing to the further improvement of a brake control when fade is generated during ABS control. SOLUTION: The brake hydraulic control device is equipped with a brake assist control means (BA control means 23) for boosting the hydraulic pressure in a wheel brake with a pump, a brake hydraulic control means (ABS control means 22) for reducing, holding or boosting the liquid pressure in the wheel brake, a first determination means 30a for determining whether or not an upstream side brake hydraulic pressure of an inlet valve is a predetermined value or more, a second determination means 30b for determining whether or not the differential pressure at the upstream/downstream brake hydraulic pressure of the inlet valve is a predetermined value or more, and a pressure increasing amount change means 31 for increasing the pressure increasing amount by a brake assist control means on the condition that an upstream side brake hydraulic pressure is determined to be a predetermined value or more by the first determination means 30a, and the differential pressure is determined to be a predetermined value or less by the second determination means 30b.
