Use a syringe to "push" fluid from the caliper to the M/C. Should be able to get large syringes from a horse equine saddle & tack store.
Use a clear vinyl tubing to the caliper bleed screw.
"Inject" the new fluid into the caliper's bleeder screw.
Be careful to not overfill your M/C!
I just did this **** new master, new lines and empty calipers. I alternated tapping the brake lines with a screw driver and pumping the lever till no more bubles came up out of the master, took awhile but it worked.
