The outside pad on both front wheels is being dragged by the disc a few millimetres until it clicks very loudly against the locking pin. The inner pad doesn't move. It sounds for all the world like duff cv joints, which is what I thought it was, took a wheel off to investigate, cv's perfect. Noticed the movement on the pad. Same, outer pad, both sides. Disks and pads renewed 2k ago, also new calipers. Really noisy and annoying. Anyone come across this before. I would search but the link won't work on my iPad, thanks to an Apple upgrade...
