I got this tool for xmas, mostly hoping to save my wife the hassle of pumping brakes for me. But when I assemble the tool with the cup for bleeding brakes, it won't hold vacuum--the lid doesn't seal tightly enough. Anyone have experience with this? I haven't tried to bleed brakes yet, but loaned it to a buddy who said it didn't work for him. I'm guessing I have to make a new cup that actually seals.
thanks
