Default Bypass the brake booster audi 90 cs q?

So when I got my steering rack fixed in my 90, the mechanic somehow damaged the booster. His elegant solution to the problem was to simply unhook the booster, so that the brakes were not powered. Of course I didn't like this setup so I had him reconnect the booster, and I lived with the constant squeaking for a while. Now however I believe that the booster is actually letting air into my system, as my clutch has been getting consistently lower and lower to the floor, despite the fact that I replaced both the the slave and master cylinders for the clutch. What I would I would like to do as a temporary fix is bleed the air out of the clutch pedal to restore it to the correct positon, and temporarily disconnect the brake booster until I get a new one ordered.....does anyone here know how to tackle this task or have any words of wisdom for me? Thank you for any help you guys can throw out!

Need to know exactly how the brake booster is damaged. If it is the plastic fitting a repair can be made. If the internals on the booster are damaged (not sure how that could be done) then you need a good booster.

The loss of brake fluid should not be related to the booster problem. If the clutch or brake master cylinder is old..it may have given up the ghost when being bled ...it happens. Bleeding the system will move the rod further in the cylinder, past the wear in the bore and crap out the seals.
