try bleeding your breaks and check if your brake booster is leaking.

I get the whooshing sound sometimes, after the car's been stood for a couple of days or so. Definitely the brake servo (booster over there, sorry).I dunno what causes it, I would have thought that if it leaked then it would continue to leak, but the problem goes away after a couple of minutes, so I tend to wait. Not having boosted brakes is quite entertaining on these cars! 
I think I'll need a new servo sooner rather than later.

thanks for the replys. i bled the brakes and i have a much firmer brake pedal, but it is still not a 100%. I think i am just going to stick it out and save the 100 dollars, i dont want to waste it on BS. thanks again
