Try this; take off the calper and raise it above the MS. Make sure the bleeder valve is at the highest position. Place a spacer, such as a piece of wood, between the pads and the back of the caliper. This keeps the piston(s) from popping out. Pump the brake to bulid up pressure and crack the bleeder valve. I'm assuming that you have a clear hose attached to the nipple. Catch the fluid in a container. Keep doing this until the air is gone or, if you are changing out old for new, the fluid is clear.
Reverse bleeding works well for the front brakes as the MS is so high up. The rear is harder because the calper and MS tend to be at close to the same level.
