'67 Fry Fix
I didn't get a pic of the dust seals on the calipers, but the dust seals on the outer pistons were worn away on the bottom due to a ridge on the rotors, see pic.
I checked the set I took off the car a decade ago, same scenario.
Since my brakes are not that old, rotors and pads have plenty of life left, and new studs, I'm using them as-is.
Replacing seals and dust seals, and ground down the ridge.
