The pistons are moving freely at the moment. I'm able to easily push them in with one finger and the reservoir cap on.
I'm not ignoring your advice, and was going to try changing the seals as the next step (cheaper than £700 worth of calipers), but can you explain the mechanics behind it. How can leaking seals cause the pistons to stay out and the pads to bind?
I read on another post that the pistons don't automatically retract, but are pushed back by tiny movements in the disc against the pads. There will always be a small amount of contact on the disc because of this. If this is true, changing the seals would only help with breaking issues, and not releasing the breaks/pads afterwards?
