Ok slayerized6 you have answered questions of mine before too so thanks! I just returned the master cylinder, now what you are saying perhaps that should have been kept 'just in case' so to speak. I didn't know that air can get in but with no fluid getting out - thats the thing how the system didn't seem to have lost brake fluid. Now I'm thinking it was the master cylinder and the same dang thing is going to happen again.. well I will let you know. She's got new drums tho'(and an alignment today)
