my pistons are about double bad, polished up the pits are still deep, look like yours before cleaning for the last 3/8 inch, how deep is the main seal, 1/4"? should be OK.
Might have something to do with gravel road and sodium chloride for dust control.
I can see stainless pistons being useful, but that housing material is still gonna corrode and gum it up. I can probably do ss pistons at work, if I buy beer for the lathe operator.
Perhaps someone sells ss calipers.
Pistons should be loose you say, nope, had to use a c-clamp to get it back in, and that didn't push out the other one. Will have to watch disc temp, and hope my economy improves soon.
