Hi All

I have a 1998 Audi A6 1.9tdi , recently I found the brake pedal travels a fair amount when braking. I have narrowed it down to a possible faulty brake master cylinder.
Can someone tell me if its possible for the MC to be unbolted and pulled out of the plenum chamber without having to remove anything else such as the brake servo. I ask as there is very little space there for it to move and wanted to know if anyone else has done this or has an idea before I get stuck. Thks
