BRAKING DEVICE FOR VEHICLE

A braking device includes a stroke simulator, a hydraulic pressure generation unit, a reaction hydraulic pressure detection unit, a master hydraulic pressure detection unit, and a bottoming determination unit. The stroke simulator includes a cylinder and a piston slidably movable inside the cylinder in conjunction with an operation of a brake operation member. The stroke simulator causes a reaction force chamber to generate a reaction hydraulic pressure and applies a reaction force. The hydraulic pressure generation unit generates a master hydraulic pressure by driving a master piston and supplies a hydraulic pressure to a wheel cylinder. The reaction hydraulic pressure detection unit detects the reaction hydraulic pressure. The master hydraulic pressure detection unit detects the master hydraulic pressure. The bottoming determination unit determines whether the master piston is in a bottoming state based on the reaction hydraulic pressure and the master hydraulic pressure.
