Stayed in Disney for a week and went out to the car after 7 days of not driving it, started up the engine and could hear a vacuum leak when I pressed on the brake. It is coming from the plunger going through the dash to the master center. The cx9 is an 2007 and has 55,000 on it. Any advise on what to do, I went under the hood today, took our the battery and I can see no broken hoses or brake fluid leaking. Under the dash you can tell it is coming from the brake. I feel no difference in the braking of the car.

Any advise will be appreciated.
