Rear brake calipers question

[cstmn]

Hello, everyone. I will restore the rear calipers of my s3 8l. Does anyone know how many mm is the piston of the rear caliper, because I get 2 types: 38 and 41 mm ???

I think, THINK, not sure, that 38mm would be for 232mm rear discs and 41 would be for 256mm rear discs. Am not sure
