Have a a weird issue that seems to be common on here, but I can't seem to solve mine. Changed my rear hubs (they were loud, noisy, 290k on them). Put the rear driver caliper back on and it was sticking. Why simply unbolting it would make it magically start doing that is beyond me. The caliper had a leak anyway, so I replaced it. Bled it (very very few air bubbles came out). still had a ton of resistance in spinning the wheel. I noticed it would get easier at some points, ok had the rotor turned, it was def warped, that helped, but i still have resistance spinning the wheel.
I cracked the bleeder open to relieve pressure on the piston, still resistance, so I don't believe it's the lines have failed internally. my e-brake appears to be disengaging fully (though I am going to just disconnect it completely tonight when I continue diagnosis), and going all the way back up to the stopper.
I'm gonna turn the piston back in tonight with a piston tool, undo the lower caliper bolt and rotate it some (i read that on here searching through old posts, I had never thought to do that) bleed again to see if anything else comes out, then 3 pump brake, 3 e-brake handle pull and see if the resistance is gone.
Any other thoughts on what else it could be? New caliper came fully assembled with new mounting bracket as well so the slide pins and everything should be good to go. I don't think ABS module or it seems like all 4 would be sticking. E-brake or lines is all it could be right (Like I said, I don't think it's the lines, but I've also never dealt with screw in pistons either)? ANy other thoughts / recommendations what to check appreciated.
