Any cures/ideas for this? They’ve been bled and the pistons don’t appear sticky as the come out and retract fine in use. It’s just i can’t get them to set up without rubbing. Push the pads back into the caliper, squeeze the lever and they adjust so they rub against the disc. Unfortunately its not just a slight rub but enough that it’s very noticeable.

are they pushed in square?

Yes and they come out square as well.

Are the pads catching on the retaining pin?

Hmmm, haven’t checked that. Will have a look later.
