Hi guys
As the title says. I didn’t remember to take photos of the others before sticking them back in the callipers, these are probably on the better side but not much between them all.
This is after cleaning with brake cleanr and a light sanding with 400 grit. There was a clearly visible line of dirt when I got the pistons out and all the corrosion is in that area, above the seals, so I don’t think there’s an issue but it’s always good to have all your opinions.
