Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the generation of fluid sound such as unpleasant hydraulic pulse, and to stabilize durable quality of a hydraulic control valve. SOLUTION: This control device comprises a four-wheel independent brake power controlling means (j) which independently controls wheel cylinder pressure generated by a brake hydraulic pressure system (i) in each four wheels, according to a detected brake operating power equivalent value and a vehicular movement state. hi this case, a master pressure variable means (k) variably controlling master pressure which is input pressure to the brake hydraulic pressure system (i) is provided between a hydraulic pressure source (d) and the brake hydraulic pressure system (i). A master pressure controlling means (m) controlling the master pressure variable means (k) at minimum hydraulic pressure necessary to ensure the maximum wheel cylinder pressure of each wheel cylinder pressure applied to the four wheels.
