That is what I thought. I didn't want to see you go through the trouble and expense of the booster. THere is a seal in the rear of the master cylender that can go bad and leak into the booster. I really think that is what is happening to yours. If you unbolt the MC from the booster, you will most likely see that the back of it is wet and it needs replaced. It is easier to replace and less expensive.
Let me know if you have other questions.
