A brake control device includes a pressurization device having a first pressurization device for pressurizing the brake fluid supplied to wheel brakes in response to the driver's operation and a second pressurization device for pressurizing the brake fluid supplied to the wheel brakes independently of the driver's operation; a first detecting device for detecting a displacement of an input member of the pressurization device or an output pressure of the pressurization device; a second detecting device for detecting the condition of the vehicle; and a control device for memorizing relationships between a driving signal of the second pressurization device and the displacement of the input member or relationships between a driving signal of the second pressurization device and the output pressure of the pressurization device as control maps corresponding to the variety of the condition of the vehicle and for controlling the driving signal of the second pressurization device on the basis of the control map in response to the value detected by the first detecting device and the condition of the vehicle detected by the second detecting device.
