I installed a dual reservoir style MC, I did a bench bleed before installing. Once hooked up to the lines I found the vacuum method using a hand pump wasn't working for me. What solved my problem with a dry system was to attach a hose to the brake cylinder bleeder screw. It was long enough for me to rig it up so it was held higher than the MC. I filled it(using and eye dropper) sounds ridiculous. But each time it pumped air out it sucked fluid in. Before you know it all the air was out. After much time wasted pumping etc this is the way I would approach another situation of the same when starting with a dry system. that my 0.02
