You are the winner. There is a thing called a "dump valve". It is a valve at the brake pedal that releases the vacuum when you press on the brake. It does not slide on a collar as far as I could see, it just sits there. However it is in the location you said and did pop out of place. So everyone was right. I thought it was something to do with a brake switch and it was sort of. My friend guessed vacuum leak and he was also technically correct.
Thanks everyone. Now if you can tell me how to fix the speedo which bounces, makes noise and reads about 20% high.
