An object of the present invention is to provide a brake device in which brake feeling can be improved. In response to depression of a brake pedal 6, an electric brake 5 mounted on the rear side starts to generate a braking force at the time of stroke h1 before a fluid pressure brake 4 mounted on the front side starts to generate a braking force when the stroke reaches stroke h2. In the conventional art, the braking force on the rear side is set according to the fluid pressure on the front side, and braking can be controlled only by the response of the fluid pressure.

On the other hand, in the present invention, the rear side can generate a braking force prior to the front side, whereby it is possible to reduce rigid feeling, and therefore improve pedal feeling.
