Abstract
A brake apparatus includes: a master cylinder that forms a driving fluid pressure chamber, which drives master pistons as brake fluid is supplied and discharged; a pressure adjusting part adjusting a driving fluid pressure of the driving fluid pressure chamber; a reaction force generator that forms a reaction force chamber and that is configured to generate a reaction force fluid pressure in the reaction force chamber in accordance with an operating amount of the brake operation member; a brake fluid path, which connects the reaction force chamber to the driving fluid pressure chamber, and a valve device configured to block, at a current-on state, flowing of the brake fluid, and that communicates, at a current-off state, the reaction force chamber to the driving fluid pressure chamber through the brake fluid path to enable the flowing of the brake fluid.
