I'll ring Martin from Reyland for advice too but you never know someone here may have had the same problem. I've just fitted brand new AP four pots on 315 discs (Which I believe are machined down to that size).

Just been for my first run and something sounds like it is rubbing. I had clips that go in against the back of the pads to secure them with this set and I'm sure that they are touching the edge of the disc. Anyone else had this problem or an alternative idea of what the problem might be?

My other set didn't have these clips - just the screw in longitudinal bolt to stop the pads coming out.

Not going to pull them off again tonight - guess it might be obvious when I do though. Just thought I'd ask anyone if they had the same problem or similar?
