I have recently upgraded my R.M. Powerplay Hope brakes from the Tech3 V4’s to the Hope Tech4 V4’s, new Hope discs. I have Hope pro 4 hubs and all four calipers never seem to get centered on the disc. I align the calipers on the discs by loosening the caliper hold down bolts, pull the lever on the master cylinder and retighten the caliper hold down bolts. No pad to disc rubbing.
