A brake booster is provided having a force input element that is or can be connected to a brake pedal, a chamber arrangement with a working chamber and a vacuum chamber, and a control device with a control valve. The working chamber is selectively connected to the vacuum chamber or to the surrounding atmosphere as a result of a displacement of the force input element. The control valve has a valve element that is selectively prestressed into sealed abutment on a first valve seat provided on the control valve housing or into sealed abutment on a second valve seat provided on the control piston of the control valve by a tension spring. In order to reduce the actuating force, a pneumatic function chamber is selectively isolated from the surrounding atmosphere by the valve element or connected to the vacuum chamber or to the surrounding atmosphere by the force input element.
