I have a loss of pressure in my brakes and what sounds like air or maybe fluid swishing from the servo. How can I tell if its my servo or the brake bomb? Or possibly air in the system somewhere?

Some brake info by clicking on the power brake and steering label at the front of the car in the diagram at the link below. Follow the various hyperlinks to more brake-system related info.

Thank you. I think it's most likely the master cylinder. What are some symptoms on our cars? If it sits for a day the brakes will go completely to the floor with almost no resistance and feel spongey.and the swishing sound is coming from right under the brake fluid reservoir. But when running my brakes feel completely normal, stop fine, good resistance but I can still hear the slight swishing sound.
