Brake system including a master cylinder with an elastic pedal feel element

A brake system comprising:

• a brake pedal;
• a master cylinder including a first master chamber, a second master chamber, a first master piston, and a second master piston, the first master piston being directly displaceable by operating the brake pedal and the second master piston being a floating piston and separating the first master chamber, which is between the first master piston and the second master piston, from the second master chamber;
• a first hydraulic circuit including at least one first hydraulic wheel brake;
• a second hydraulic circuit including at least one second hydraulic wheel brake;
• and
• a hydraulic pressure supplier including an actuator for pressurizing the first hydraulic circuit and the second hydraulic circuit depending on an operation of the brake pedal in a normal operating mode of the brake system,
• wherein the first master chamber is hydraulically connected to the first hydraulic circuit for pressurizing the first hydraulic circuit in an emergency mode of the brake system,
• wherein the second master chamber is hydraulically connected to the second hydraulic circuit via a first cut-off valve for pressurizing the second hydraulic circuit in the emergency mode when the first cut-off valve is open, while the second master piston can be locked in a locking position by closing the first cut-off valve in the normal operating mode, and
• wherein an elastic pedal feel element is arranged in the first master chamber to be in contact with the first master piston and the second master piston for generating a pedal force when the brake pedal is operated while the second master piston is locked in the normal operating mode.
