    Weird. I have no idea. Even if it's something like a leaky diaphragm in the brake servo, I wouldn't think it possible that it could keep it up for 6 hours.

    We had this with one of our vehicles, never did find out what it was, but never caused any problems,

    You could have a small air leak on the vacuum side, the noise your hearing is possibly the servo diaphragm 'groaning' as the air passes around it.

    Don't know how loud we are talking, but it's not your radiator cap drawing air in as it cooling down, is it, try loosening your radiator cap, when it's doing it,but not if it's boiling
