A brake device may include: a brake piston configured to press a braking member against a brake member rotating with a wheel; a hydraulic system configured to press the brake piston toward the brake member; an electric-powered system comprising a movable element configured to press the brake piston toward the brake member; and a controller configured to execute a parking brake operation by using the hydraulic system and the electric-powered system. In the parking brake operation, the controller may be configured to apply a pressing force of a predetermined value or greater to the brake piston by using both the hydraulic system and the electric-powered system. The predetermined value may be greater than a maximum pressing force that the electric powered system is capable of applying to the brake piston.
