9 bolt iron caliper rebuild advice
I want to clean up and rebuild iron 9 bolt calipers and I'm trying to get the main seals out of the cylinders and they don't seem to want to move and I don't want to mess them up before I have new ones. Any tips on how to get them out intact and without messing up the cylinder? What about the ring seal further in? What about installing new ones?

Those have the freeze prone screw in/out pistons.
