I bought the new M985 brakes a couple of months ago. They were feeling a little squishy, and when the bike is tipped upside down lever goes to the bar. So I decided to bleed them. No big deal, I've bled 100's of brakes before. Did the front one, fine. Started the rear one, and at the lever reservoir it started to leak when I bled it. The reservoir will not hold any fluid! It leaks out the black part (see pic). I have no idea whats going on, the bike has been sitting for a couple weeks, but was working fine before that. Any idea?
