I'm just guessing here, but perhaps the brake booster is leaking. It uses engine vacuum to provide braking assistance. It's the large canister thing, usually on the firewall, behind the master cylinder. If it is indeed your brake booster leaking vacuum, you may also notice a change in your idle speed or may experience rough idle. Your engine's computer adjusts your engine's idle according to vacuum. If vacuum is lost anywhere on your engine, the computer may adjust idle inacurately. Whooshing brake sound + changed idle may be diagnostic of a leaking brake booster, although idle won't always change.
