Abstract
The invention relates to a method for degassing a hydraulic vehicle brake system that has an external-force service brake system and a muscle-powered auxiliary brake system. For the degassing, brake pressure buildup valves are opened, preferably successively, so that brake fluid flows through the brake pressure buildup valves, disconnection valves and a master cylinder and reaches a brake fluid reservoir. The brake fluid positively displaces any brake fluid containing gas from the vehicle brake system into the brake fluid reservoir, where gas bubbles can escape from the brake fluid. Compressibility of the brake fluid from gas bubbles is avoided.
