Having problems with your 1997 Lincoln Mark VIII ?
Breaks when pressed make a hissing noise, i have pressure on the line but no breakes?
Either the break booster is bad or there is a hole in the vacume line comming from the engine to the booster, is the hissing noise you hear comming from under the dash? if it is then the booster is bad, if its under the hood chk.the vacume line to the booster. If its a vacume leak it will idle higher than normal too.
