Could also be leaking from the Brake master cylinder.  Removing Instrument
cluster cover and inspect the fittings and where the Master Cylinder attaches
to the brake booster for leaks.
I have these new if you need one for $80.
You can call in your order or order on-line with a credit card on the website
(see address below).

Thanks,
