Trying to put the finishing touches on disc brake conversion today. I'm trying to get the brakes gravity bled, but I can't get any fluid to move at all with the bleeders wide open. I've seen something referring to this button on the front of the prop valve. Do I have to do something with it while I'm gravity bleeding?
