There's a correct sequence to bleeding the three valves on the front calipers. It has three because it's a two circuit system, there's two pistons instead of on on the fronts. The do this in case one circuit fails, you still have some brakes on the other piston. I don't know the correct sequence off hand, you need a book to get it. I think it's like this: Lower nipple first, Top nipple, outer, next. Top nipple, inner to finish. Do the same on the other side.
