A vehicular brake control method and apparatus having a controller that controls a pressure of a supplied operating fluid to the wheels. The vehicle brake control apparatus includes brakes that apply braking forces corresponding to the pressure of the operating fluid to the wheels. A pump is provided that force-feeds the operating fluid. A valve is disposed to adjust the pressure of the operating fluid that is force-fed from the pump. The controller performs an operation control of the pump and the valve to control the pressure of the operating fluid to be supplied to the brakes when the controller determines that the braking forces are to be applied to the vehicle. The controller controls a pressure-increasing gradient of a fluid pressure by controlling both the pump and the valve during a pressure-increasing control for increasing the pressure in the brakes.
