To provide an brake hydraulic pressure controlling device for a vehicle comprising inlet solenoid valves of normally open type interposed between a master cylinder and each wheel brake and an outlet solenoid valve of normally closed type interposed between the wheel brake and a reserver, in which coils are installed in the inlet and outlet valves and current feed control elements to control the current fed condition from a power supply to the coils are connected with the coils in series individually, whereby capable of enhancing the controlling performance when the solenoid valves are subjected to a linear control.
The resistance value of a series circuitry connected with the power supply 45, including the coil of the outlet valve arranged as capable of being changed over between the full open condition and the full closed condition and the corresponding current feed control element, is set larger than the resistance value of a series circuitry 44 connected with the power supply 45, including the coils of the inlet valves 5A-5D capable of being put under a linear control in the full opened, full closed, and half opened condition and the corresponding current feed control element 46.
