On my Deuce, I always had the car in a very nose down attitude when bleeding. Probably silly. The rear backing plates mount at an angle and with worn shoes or drums the wheel cylinder has a lot of volume in it. I was trying to get the air out of the cylinders.
Here is a random thought. It might be feasable to use a suction blow gun to vacumn fluid to the wheel cylinders. Just hook up the hose to the fitting and watch for fluid coming out??
