69- (a different Greg responding here) - get a piece of hose that fits the bleeder fitting on the rear caliper- if you don't have any, the vinyl hose at hardware stores is perfect. Open the bleeder and install the hose then put the open end of the hose into a soda bottle with enough fluid to cover the open end of the hose- 1/2" will do. Then slowly pump the pedal about 6-10 times. Check the level in the bottle to see if it raised and in the MC to see if it dropped. This is a great quick way to push the air out & fluid in. once you have fluid from all 4 wheels, then go back and bleed your favorite way. Putting the hose end into fluid prevents the back flow of air when the MC piston returns. Instead it will suck up some fluid.
