Sticky Porsche Front Caliper

The front right caliper on my 89 cab has dragged for years. Sometimes it's minimal, but if I jack up the car I can feel way too much rotation resistance. If I pry the caliper open the drag goes away.

It is not a 'closed off' flex line, I replaced the lines with new braided SS hoses a year or two ago. It is not lack of lubrication on the top slider pins, they are fine. It is not old brake fluid, I have bled the brakes a half dozen times, the fluid is clean and clear.

What's left? New seals in the calipers? That's sort of the last thing I can think of.
