Provided is a brake device capable of suppressing an output pressure overshoot or undershoot. A vehicle brake device according to the present invention is configured such that a pressure adjusting device includes a piston driven by a difference between force corresponding to a pilot pressure and force corresponding to an output pressure, wherein as the volume of a pilot chamber is changed by the movement of the piston and the flow rate of liquid flowing in and out of the pilot chamber increases, the amount of movement of the piston increases with reference to the piston position in an equilibrium state where the force corresponding to the pilot pressure and the force corresponding to the output pressure are balanced, whereby the flow rate of the liquid flowing in and out of an output chamber increases. A control means, when it is determined by a limitation necessity determination means that the gradient of output pressure should be limited, implements at least one of boosting gradient limit control for opening a depressurizing electromagnetic valve during boosting control, or depressurization gradient limit control for opening a boosting electromagnetic valve during depressurization control. |
