No, the shoes are on correctly. When the system is working, things go fine and I can back up. That occurred when the adjusting rod between the booster and MC was too far out, and the fluid was not able to go back in the MC, causing brakes to be "on" all of the time.
I did bench bleed the MC today. I also capped both ports and put MC back on truck, to find the pedal solid (indicating no leak in the MC seals). I also found that, per an article that I read, it does not appear that the MC has residual pressure valves in it ( I couldn't see them with flashlight, and a paper clip pushed into the outlet port went in over an inch). I'm thinking that also could be the issue.
Next steps are adding residual valves, bleeding system again (running this time, as has been suggested) and seeing how that helps. If still a problem, will add heat shield, as MC and lines are only about 3-1/2 inches from the exhaust pipe on that side. If all that doesn't work, then I guess I'll have to put a unit on the firewall, as much as I don't want to do that.
Thanks for all of the help!
