I would double check and make sure you have the calipers on the correct side of the truck. I'm pretty sure there is a left and right side and if you get them backward then you can get all of the air out of the caliper.

 

Ok I will check that and make sure as well. I'll be working on this Sunday. My first day off so I'll have time to do this. And your right it, they could be backwards. I pulled
The rearend off and put a different one on. Had my nephew change the calipers.

 

Good point the bleeder needs to be on the top of the caliper otherwise you wont get the air out.

 

Well come to find out. Caliper was wrong. Bleeder was on bottom. Thanks for all the help. Now off to another issue.
