Here are some pictures don't know if they will help. I have checked diagrams on the plumbing for the distribution block and everything looks correct. I just loosened up the Mc and slid it out a little ways but there was no change or relief on the calipers. I guess what is puzzling me is after a minute or two the caliper will release enough to turn the rotor.. I also loosened the bleed valve and it did relieve pressure and then I broke the hard line and rubber hose connection and it also released the caliper somewhat.
