I got some new front brake pieces - Master cylinder, brake line, pads, piston and seals.

Ended up bleeding it the way I am going to describe.
Note: the photos are of something I had laying around, not the new stuff.

Items used:
Hi Temp synthetic brake fluid
2- 10cc disposable syringes (got mine from a veterinary supply)
4" of large silicone tubing (5/32" id)

I removed the caliper from the bike, put a piece of scrap between the pads and hooked up the tubing as shown. To start, have the master cylinder higher than the caliper. Fill a syringe with fluid, hook it to the tubing, open the bleeder, force the fluid into the system, close the bleeder. Continue until you don't get bubbles in the fluid entering the master cylinder. If you get too much fluid in the master cylinder, suck some out with the extra syringe. I do not ever re-use that fluid.

Next:
Fill the master cylinder, collapse the syringe, and put back on the tubing.
Have the caliper higher than the master cylinder. Keep the syringe vertical.
Put pressure on the brake lever, open the bleeder (fluid should enter the syringe)
Close the bleeder before releasing the lever! Continue until the fluid is free of air.
It may be overkill, but I repeated this after re-installing the caliper.
