Braking system for a motor vehicle

A braking system for a motor vehicle, comprising:

• a first module having at least one reservoir port and a module port;
• a second module having a plurality of wheel ports;
• a first electrical pressure supply device arranged in or on the first module and connected on the pressure side to the module port and connected on the suction side to the at least one reservoir port;
• a second electrical pressure supply device arranged in or on the second module and connected on the pressure side to the plurality of wheel ports;
• and
• a first separation valve connected in the second module between the module port and the wheel port;
• wherein the second electrical pressure supply device is connected on the pressure side to a connection between a first separation valve and at least some of the wheel ports;
• wherein the first separation valve has a first valve seat and a second valve seat, wherein the valve seats hydraulically connected in parallel with the second valve seat having a larger passage than the first valve seat;
• wherein the first separation valve is normally open;
• wherein the first valve seat and the second valve seat are jointly closable by actuation of the first separation valve;
• and
• wherein the second valve seat is spring-loaded in such a way that, if the first separation valve is not actuated, the second valve seat only opens if a positive pressure on the side of the second electrical pressure supply device is less than a threshold value.
