2004.5 front brake part #'s please (pads & rotors)?
I'll need to do brakes this springtime on my '03 c230k ss. I've got a set of the 2004.5 front brakes I'd like to put on, but am at a loss on part #'s for the pads & rotors to use. Can somebody help please?
I'm looking for stock part #'s for the 2004.5 pads and rotors. I'd also be interested in performance/aftermarket upgrade part #'s too.
BTW, I read thru the brake upgrade thread in the mod's sticky - a lot of good info there, but I didn't see these part #'s. Also searched for quite a while to no avail. I also went to the various websites and only get stuff like 'front rotor for 2003-2006 c230k', which I know can't be right.
Thanks in advance!!!

Just thinking some more ... Could it be as simpe as just ordering the C32 pads & rotors? But I thought the C32 had slightly larger brakes/pads/rotors than the 2004.5 ... ???

If 4 then I believe you can just order C32 stuff.
But hopefully others will chime in to be sure.

4 pistons (2 on each side). They have the 4 socket head bolts on each side (vs. the 2 star head bolts on the 05+).

No. The 2004.5 4-piston brakes are different than the C32/C55/C350 4-piston brake calipers.

e, you are a gentleman and a scholar. Thanks!! For posterity's sake, copied from the link above:

Interesting...I wonder if 16" wheels would fit on the 2004.5 brakes?
Well, now that you know that the AMG size pads will work,
I highly recommend the Akebono pads.
You can source them from tirerack.
They last forever!!! Compared to the MB pads which last like 20-30K.
