Yes, the caliper alignment with the CPS bolts can drive you nuts. Here’s what I do. Loosen the CPS bolts, then squeeze the lever tight to line up the caliper. Then only snug the CPS bolts (not real tight). Check and see if the rotor is running free (no rub). If not repeat until there is no rub. Do not squeeze the lever when you tighten the CPS bolts to their full torque value. That seems to be the trick to get things to work. You will need to get used to doing this because every prolonged downhill seems the warp the rotor. You can also get the Park rotor adjustment tool to get the warp out. Good luck.
