4 piston calipers question

An update on the front brake refresh. I have both calipers fully torn down and cleaned. The grease trick worked well to get the pistons out and things came apart fairly easily.
So the result is that I have a hint of pitting on 3 pistons, and 5 that are perfect, and the caliper bores look great so I will now be on the hunt for 3 pistons and 8 new rubber boots with rings and then I’m very comfortable that my front brakes should be good as new
