Started last May on the "minor" () refresh of my 75 280, now it seems that everything I put back in that was fine last May, now doesn't work, i.e. clutch master won't pump fluid when connected, engine won't start, more electrical gremlins than I care to think about, brake booster making whooshing noise and can't bleed the brakes, moaning/clicking noise from the steering rack after new bushings, tie rod ends and ball joints. I'm getting close to the end of my rope, but can't quit because I have to much time, money, blood and sweat into this thing! The best thing to happen so far is I learned how to weld(sorta), prep paint(kinda OK) and polish, and got some valuable education from this site.

Pretty normal for a car that's been sitting for many years, except for the moaning steering rack. If you put the old parts back in maybe they weren't so fine. The good news is that all of the other things have been covered many times on the forums.

Check that you didn't put the calipers on the wrong sides with the bleeder on the bottom. you should be able to bleed them even with a whooshing booster. The whooshing probably means that you need a replacement booster.

Zed, this car was a daily driver prior to starting to work on it, but it had some issues when I decided to do a rolling restoration and after getting into the project found lots of other stuff which I expected, its just real frustrating when you know something worked prior to taking it off and now it doesn't. I've used the forums here extensively and they have been a great help in solving some of the issues. Thanx for your response.
