Claim:
1. A method for operating a brake system for a vehicle, wherein the brake system includes a master brake cylinder coupled to an electromechanical brake booster having a booster body, the method comprising: controlling at least one wheel outlet valve of at least one wheel brake cylinder of at least one first brake circuit of the brake system in its open state, while taking into account at least one provided sensor signal with respect to an operating strength of an operation of a brake operating element situated on the master brake cylinder in such a way that a brake pressure buildup in the at least one first brake circuit becomes able to be limited to a response pressure of a fluid accumulator device of the respective brake circuit; displacing the booster body from an initial position relative to the master brake cylinder in a direction towards the master brake cylinder by a specified adjustment travel into an end position, in order to raise a travel differential between an input rod of the electromechanical brake booster and the booster body, during the step of displacing the booster body the at least one wheel outlet valve remaining opened; and displacing the booster body from the end position relative to the master brake cylinder in an opposite direction away from the master brake cylinder by the same specified adjustment travel back into the initial position, in order to reduce the travel differential between the input rod and the booster body, during the step of displacing the booster body from the end position back into the initial position the at least one wheel outlet valve being present in a closed manner in such a way that hydraulic fluid is sucked away from wheel brake devices that are coupled in a fluid manner to the brake system and assigned to wheels of the vehicle for a reduction of a hydraulic fluid pressure existing in the wheel brake devices.
