Zusammenfassung:PURPOSE: To allow a six-solenoid type brake fluid pressure control device to retain rear-wheel-side fluid pressure when front-wheel-side fluid pressure is reduced. CONSTITUTION: A solenoid valve 22 is provided in an oil passage 18 which communicates a master cylinder 14 with a front-wheel-side wheel cylinder Fr, and a second solenoid valve 30 is provided in an oil passage 20 which communicates the portion between the first solenoid valve 22 and the front- wheel-side wheel cylinder Fr with a rear-wheel-side wheel cylinder Rr; a second reservoir 34 is connected via a third solenoid valve 36 to the portion of the oil passage 20 upstream of the second solenoid valve 30, and a pump 40 for pumping brake fluid up from the second reservoir 34 also has its delivery port connected to the portion of the oil passage 20 upstream of the second solenoid valve 30.
