I back bleed and tickle the lever.
Go to the local pharmacy and get two big syringes, and then the hardware for clear tubing. Fill one with fluid and connect to nipple via tubing. Open nipple and slowly push the fluid up the pathway. Have a buddy tickling the lever and removing fluid with the other syringe, as the level rises.
Have the bike on the side stand, with the handlebars turned to the left.
EDIT: Have your buddy occasionally push down the high loop of brake tubing ... make sure the MC is the high point.
