more than likely your rear seal is out of your master cylinder and leaking by. You won't see any fluid because the front seal in the booster is deteriorated and the fluid is going into the booster. I just went through the same issue 2 weeks ago...

I got my booster through NAPA, and master cylinder from AutoZone.....
