The diaphram in the booster is probably cracked and leaking
They are rebuildable if you can get a new diaphram
or get a good used booster although these aree all almost
20 years old which is really getting old for the diaphram.
Brian Holm or Disortex probably have rebuilds ready to go

Subject: [Peugeot-L] 505 failed brake power assist.
The power assist on my 85 505TD has failed. For a period of time
before it did, whenever I would release the brake pedal I would hear
a "wooshing" sound which I took to be a vacuum leak. The wooshing
would stop after a short time, and I never detected any loss of
assist until it failed completely. The wooshing grew louder and
sometimes of greater duration; at times it was a loud whistling
sound. Finally the power assist failed and the sound is still
there, but almost inaudible. Now the brakes seem to work just
fine,it's just that they require greater effort. Any ideas on the
nature of the failure and possible fixes? Lastly,(and most
importantly,) Is it safe to continue using the car as it is or am I
risking further damage to the brakes and a possibly unsafe situation?
Thanks for your time.
