Claim:
1. A braking system for motor vehicles using a pressure medium applied to one or more wheel brakes and which, in a brake by wire operating mode, can be controlled both by a vehicle driver and independently of the vehicle driver, and is preferably operated in the brake by wire operating mode and can be operated in at least one fallback operating mode, comprising: a brake master cylinder, which can be actuated by a brake pedal and having at least one piston and at least one pressure chamber, to which can be connected to a brake circuit and the wheel brakes, an electrically controllable pressure supplying device for actuating the wheel brakes in the brake by wire operating mode, a simulation device having at least one elastic element, which provides an acceptable brake pedal feel to the vehicle driver in the brake by wire operating mode, wherein the simulation device has a hydraulic simulator chamber, which is hydraulically connected, via a first hydraulic connection to the pressure chamber of the brake master cylinder and which is further communication through a connection with an electrically actuated isolation valve with a pressure medium reservoir under atmospheric pressure, and a media separating device arranged in the connection between the simulator chamber and the isolation valve, wherein the media separating device does not allow fluid to flow through the media separation device from one side to the other.
