S6 C6 brake caliper piston dimensions

Hi there!

I need front brake caliper piston dimensions for C6 S6, as I think they are the culprit of uneven brake pads wear. I know, the diameter is 60mm, but I don’t know the height of them, and I would like to order them before caliper disassembly, so if anyone could provide me with the other dimension, it would be great.

Thanks

I’ll answer myself. They are actually 42mm in diameter, and 55 in length. Audi claims wrong diameter
