I just use a hose on the bleed nipple, and attach a large suringe (got a bunch from the local drug store for free) add at the top, pump that handle and open the bleeder suck with the suringe and continue in that fashion till you get no air bubbles for about 2 or 3 pulls, bleeding brakes is 100 times easier with two people, so if you have a helper, use him/her for this it will go much quicker!

Best Method
Drain your old brake fluid out off system,fill a large syringe with new brake fluid attach a hose to syringe and the other end of the hose to bleed nipple on caliper,open the bleed nipple and pump the new brake fluid into the system till you see the resevoir filling up,then close the bleed nipple,you'll find this methods a lot easier as air will all ways rise, so with the brake fluid being pumped into the caliper up the line will push all the air out the top at resevoir.

There are times no matter how you do it the lever won't firm up. I have found if you loosen the banjo fitting and squeeze the lever it will expel any pesky bubbles that won't come out the regular way. Just make sure you have a rag over the fitting to catch the fluid coming out.
Did a rear brake on a Sportster awhile back and that was the only thing that finally worked.

Yup, sometimes a little bubble gets trapped at the top fitting near the banjo. I loosen the mounting bracket and remove the resivoir from the bars and with the lid off, tilt the resivoir so the banjo is as low as you can get it in relation to the rest of the resivoir without exposing the little holes inside below the surface of the fluid. Now gently tap near the banjo with a screwdriver or something similar until the last bubble pops out. You may have to very carefully work the lever once to get it to pop out.
Reverse bleeding is the way to go. Syringe at the bleeder, pump fluid up to master cylinder and watch it fill.....
