So Its time for new brakes. Picked up a micrometer today to measure my rotor size.

On the stock OEM brakes on my 2005 C55 it says min 28.0mm. I measured them and they are at 28.6mm.

So rightfully thinking I need new rotors right? Or atleast soon.

So I picked some up at the dealer and they say on there min 26mm. So I decided to measure those and they came up at 28.2mm brand new.

Essentially saying that my already used rotors are still thicker than the brand new ones.

So now I am confused as of whether or not I should even change the rotors???

~60,000miles on the car and had it since 8k and have not changed the brakes yet. (just for some history)

You sure you bought the right rotors? The C55/C32 rotors are the same diameter but thicker compared to the regular W203 Sport rotors.

Wrong rotors. I knew something was up.

I changed mine at ~45k. I have 83k now, and got my pads replaced at around 80k. I did not do the rotors, but will probably do them the next time I do the pads.

C230 Sport rotors are slightly smaller in dia compared to the C32/C55, even the card equiped with the 2004.5 4-piston fixed calipers.

Yeah the tech gave me the 13's not the 09's which is what are needed for the 55's and I am assuming the 32's. Had the rears cut which probably wasn't a good idea but so the pad sits fine on the rears i figured it was best.
