1. A brake system for a motor vehicle, comprising:

  • a pedal unit with a sensor detecting an actuation of a brake pedal of the motor vehicle and generating a sensor signal with a desired value corresponding to a driver demand for a brake application force;

    electrically actuated brake actuators disposed at each of a plurality of wheels of the motor vehicle;

    an electronic central controller(13) evaluating the sensor signals and generating control signals for additional braking functions;

    a data bus interconnecting said pedal unit, said brake actuators, and said central controller, said data bus being adapted to exchange data blocks in a predefined, cyclically repeated time pattern; and

    an additional signal line interconnecting said pedal unit, said brake actuators, and said central controller, said additional signal line carrying a transmission of the desired value for the brake application force from said pedal unit to said brake actuators and said central controller(13) and a data exchange concerning a status of said brake actuators.
