Well I bleeded for 2 hours no luck and went to a friend and he couldn't figure it out either. Our thought is that the nipples are either leaking or they take in air through the threads. Took out a nipple and cleaned it ... no result ... I still have one hot caliper. Will reclean and then apply special grease for the calipers. No luck so far , if I can't fix it today I'm bringing it to the dealer I have no clue whats wrong ....
