Abstract
A brake apparatus activates a stroke simulator OUT valve in a valve-closing direction to increase a pressure in a wheel cylinder with use of brake fluid flowing out of the stroke simulator according to a state of an operation performed by a driver on a brake pedal. Further, when the hydraulic pressure in the wheel cylinder or a first oil passage is brought into a predetermined state, the brake apparatus activates the stroke simulator OUT valve in a valve-opening direction to cause the brake fluid in the stroke simulator to flow out to a low-pressure portion while restricting the brake fluid in the stroke simulator to a predetermined flow amount.
