PURPOSE: A brake hydraulic control system for a vehicle equipped with a pressure sensor is provided to easily perform electric connection with an ECU(Electronic Control Unit) by improving arrangement structure of the pressure sensor and to make a master cylinder used to each control system in common. CONSTITUTION: A brake hydraulic control system for a vehicle is equipped with a master cylinder forming brake hydraulic pressure according to the operation of a brake pedal, a hydraulic unit(60) having a built-in pump for flowing the brake hydraulic pressure formed to the master cylinder and pumping a wheel brake side, plural solenoid valves, controlling brake hydraulic pressure transmitted to the wheel brake side, an ECU(70) having a circuit board(72) within to control operation of the solenoid valve and pump, and a pressure sensor(80) sensing the brake hydraulic pressure formed to the master cylinder with connected with the circuit board of the ECU. An installing port, communicated with a passage(51) having brake hydraulic pressure produced to the master cylinder, is prepared to the hydraulic unit. An installing part(82) directly connected to the installing port is prepared at an end of the pressure sensor. The pressure sensor and circuit board are electrically connected through a male terminal and female terminal in assembling of the ECU. Therefore, the master cylinder can be used to each brake control system in common.
