1. A brake system for a motor vehicle comprising:
a plurality of electromechanical wheel brakes, wherein the wheel brakes each have a local brake control unit;
a brake operating unit;
a central brake control unit directly connected to the brake operating unit and to the local brake control units via a first data connection;
wherein the brake operating unit is directly connected to the local brake control unit of at least one wheel brake via a second data connection;
wherein in a normal operating moved the central brake control unit determines at least one brake demand based on first operating information received via the first data connection, and transmits control signals corresponding to the brake demand to the local brake control units;
wherein in a fallback operating mode at least one of the local brake control units actuates a respective at least one wheel brake based on second operating information received via the second data connection; and
wherein one of the local wheel brake control unit is directly connected to the brake operating unit, and wherein the local brake control unit transmits the second operating information received from the brake operating unit to the other local brake control units via a third data connection.
