Paul - when I say 'fade', i mean hard pedal, so - vacuum problem, right? There seem to be no other vacuum-related problems with the car though - the locks work fine, tranny shifts nicely etc. Mike, I'm not sure when the brake lines were done, if ever - I've only had the car for the last 6 or 7k miles. Is there a quick visual inspection that can determine their condition? Thanks again for your help.
