How did you decide to get the servo rebuilt and for those that have, what was the biggest difference. My brakes on the 6 work well, they do require a fair amount of pedal force to work, but will definetly lock up the tires. I know on other power assisted cars, when you start the car with your foot on the brake, the brake pedal will depress somewhat when vacuum is applied to the servo from the manifold. Mine doesn't really do this. Is this indicitive of a needed rebuild? I thought it might need a rebuild but when I asked my British car mechanic he said that no pedal travel was normal on start up and that the brakes were never that easy to push. Just curious about your experiences.
