The present invention relates to a vacuum brake booster for a motor vehicle brake system, having a force input element that is connectable or connected to a brake pedal, a chamber arrangement comprising a vacuum chamber and a working chamber that are separated from one another by a movable wall, a control valve with a valve element for selectively connecting and separating vacuum chamber and working chamber, and a force output element for transmitting an output force to a master cylinder, wherein the force input element is workingly connectable or connected to a transmission piston arrangement disposed in the control valve, wherein the control valve is settable in accordance with a displacement of the transmission piston arrangement along a longitudinal axis by means of the force input element. In this case, it is provided that the transmission piston arrangement is provided with at least one pressure compensation channel, by means of which a pressure compensation is effected at the valve element.
