A brake device includes: a battery connected to a power supply line; a fluid pressure unit driven by power from the supply line and applies fluid pressure to a brake; an alternator that receives power from a vehicle engine and generates power at a voltage higher than a charged voltage of the battery; a capacitor that stores the power generated by the alternator; and a DC/DC converter that converts the voltage of the capacitor to a predetermined value and supplies the converted voltage to the supply line. When the vehicle will potentially collide with a forward obstacle, an output of the DC/DC converter is set at a target higher than an output voltage in a normal state before brake actuation, or if output of the DC/DC converter cannot be set at the target voltage, the alternator is driven to connect a generation voltage of the alternator to the supply line.
