How much time are we talking about to leak down? Overnight? A week? 5 minutes? If it leaked down within a day, I might be inclined to rebuild or replace it. Remember, improperly adjusted brakes at the wheel can cause the very same symptoms, that being a low pedal that pumps up fine. Hope this helps. Jeff Ceurvorst |
