A brake actuation assembly for actuating a motor vehicle brake system of type 'brake-by-wire "as well as methods for operating a motor vehicle brake system with such a brake actuation unit

The invention relates to a brake actuation assembly for actuating a motor vehicle brake system of the 'brake-by-wire "with a brake booster. To provide a brake actuation assembly for actuating a motor vehicle brake system of the 'brake-by-wire ", which is on the one hand, the statutory requirements are met concern and on the other hand inexpensive to produce, it is proposed according to the invention that the brake booster 1 is provided as a path-controlled brake booster, so that the brake pedal 8 outside the 'brake-by-wire "is decoupled from reaction forces of the brake operating unit, and the restoring force is simulated and outside the' brake-by-wire" through the pedal travel simulator. 11
