Brake problem
I've got a brake problem with the '00 F-350 Dually. Recently, I somehow lost the inboard brake pad on the left rear. As a result, the caliper pushed the pistons all the way out and I wound up having the pedal go all the way to the floor. Evidently I lost most or all of the brake fluid. I babied the truck home and wound up with a 2-foot diameter puddle of brake fluid on the driveway. I replaced the rotor, caliper, pads, bearings and seal, and I refilled the master cylinder reservoir. Then, I bled the system at the left rear. Next I replaced the pads on the right rear (the old ones were almost like new), and I bled the right rear. The brake pedal was still very spongy, so I tried to bleed the fronts. Trouble is, I didn't get ANY fluid coming out of either bleeder valve on the front. My theory is that I lost all the fluid during the original issue and that I need to do something to refill the system again. It got late, so I decided to button everything up and come here to search out some expert advice. 
Any ideas?
THANKS in advance!!

Thanks for the reply! I shall give it a go tomorrow as soon as I can. Your advice makes sense to me, although I have pumped the brake pedal about 14 million times during the process I described. I suppose if enough air was trapped in the lines no fluid would've made it to the front calipers yet. I sure hope this solution works! Either way, I appreciate the help!!

Yep, gravity will do it.

The exact same thing happened to my F-250. but I attributed it to the truck basically sitting for 2 years while I was in Afghanistan.
Anyway, on the new caliper, is your bleed screw on the top or the bottom of the caliper? Some parts store do not know the difference, and will sell you a left caliper for the right side, or a right caliper for the left side. When that happens, the caliper fits and works, but the bleed screw ends up on the bottom of the caliper. In that condition, you will never get the air out of the caliper.

OK, I finally got back to work on the Dually. Eventually the fluid made it down to the front calipers. Getting the left front bled was a little bit hateful, but I think the problem was the bleeder valve. Thanks for all the help. I knew this would be the place to find the answers I needed!!
