These are OEM 4Pot front brake calipers from a 1998 Mercedes e320 that only had 140,000 miles on it. It was rebuilt with new seals and freshly painted high heat temperature red. These can be upgraded to fit onto the 190e or any Mercedes that only came in smaller single pot brakes.
These calipers will come with original pins, brackets and used brake pads only.
Please do your research before purchasing as there may a little to no modifications needed to fit your Mercedes.
