Patent ID: 8857923

Claim:
A brake system for a vehicle, comprising: a main brake cylinder having a first chamber hydraulically connected to at least one wheel brake cylinder for braking a wheel of the vehicle; an activating device adapted to be acted on by a driver of the vehicle, wherein in response to being acted on by the driver, the activating device acts on a piston of the main brake cylinder in order to pressurize hydraulic fluid in the first chamber of the main brake cylinder; and a pressure generating device hydraulically connected to the first chamber of the main brake cylinder, wherein the pressure generating device supplies the wheel brake cylinder with hydraulic fluid through the first chamber of the main brake cylinder to activate the wheel brake cylinder independently of a force from the driver as applied to a brake pedal during a first mode of operation, wherein the piston of the main brake cylinder has a separating element provided in a floating manner on a rod element of the piston, and wherein a first side of the separating element delimits the first chamber and a second side of the separating element delimits a second chamber of the main brake cylinder, and wherein the second chamber has a closed design and is filled with hydraulic fluid.
