Why - only one caliper works

Thanks Wilkin,

Yes it is possible that it could be the prop valve, but it is brand new from CPP.

Before I go that route though I'm really thinking if it's the rear brakes are so far out of adjustment...? I backed off the e brake and retightened but not sure if it's enough so here's what I plan on doing to make sure rear brakes are adjusted to see if I can get pedal.

I found a good pointer on how to adjust the rears while on a stand emulating the truck going in reverse.

After I get to this than I'll make sure the ebrake is correct by tightening it
right up till I can't turn the wheels then back off a bit.

Any suggestions are always welcomed and I appreciate everyone's feedback...when people say brakes are a PITA now I know why.

CPP had a bad batch of proportioning valves for a run. Went through it on a 1950 Chevy project. I googled it and learned about the run. It has since been fixed, but you could have one of the older ones.
