HYDRAULIC POWER VEHICLE BRAKE SYSTEM AND METHOD FOR FILLING A HYDRAULIC POWER VEHICLE BRAKE SYSTEM

A pedal-travel simulator of a hydraulic power vehicle brake system is connected to a brake-fluid reservoir by way of a groove between two piston seals of a power brake-pressure generator. Any air bubbles in the brake fluid get out of the pedal-travel simulator into the brake-fluid reservoir, and the piston seals are lubricated with the brake fluid.
