Brake help needed.
What causes a noise, similar to air filling a tank, when braking? It sounds like it is coming from under the dash but it could be in the engine compartment. The break peddle pressure feels firm. But I can tell that it is slowly going away.

I don't think it's your master cylinder. I had the same problem and it was my brake booster. Read this article to check yours to see if it's going bad http://73-87.com/7387garage/chassis_...on/booster.htm

I don't think that it is the master cylinder because I have good peddle pressure. The more I think about it, the more if feels like the vacuum boost is going out.

If it sounds like air being pushed out, it will mostly likely be your booster.
