Brake Pulsation still present
I just finished replacing front rotors and pads on my 05 c230.
Old rotors were lightly warped as it was giving me vibration when i am braking. Now with my new set up I am still getting that same pulsation, drove for about 10 minutes and it seems like its starting to draw same pattern on a new rotor(i maybe being real real picky). Any ideas guys?
It is Centric Premium Rotors with Akebono Euro Pads.

Have you done a proper brake pad bed in? For method see the Stoptech website.

a quarter mile at a time
sounds like you're getting wear patterns in the form of concentric rings on the face of the rotor. This is normal and won't cause pulsation.
Your pulsation is either due to lateral rotor runout or pad material being deposited unevenly. Hopefully the bed-in procedure works.
I still don't understand why people choose aftermarket rotors over the stock ones. Stock MB rotors are of more than adequate size, zinc coated to prevent corrosion, perform well and aren't excessively expensive, especially when bought online.

Fresh rear rotors cured my former judder and pulsation, although they measured within allowable tolerances for width variation around the disk(s) and runout prior to replacement.
That, and they’re surprisingly affordable. :)

+1 on checking your rear rotors. BMW replaced something like four front sets on warranty before finding the problem was at the rear on our old M5.

Exactly. MB’s OE brake hardware is typically excellent, dusty pads notwithstanding.

I dunno, the Balo rotors on the front of my car have 60,000 miles on them and are well into their second set of pads at this point. They've never had any noise or vibration issue whatsoever, and they were quite a bit cheaper than MB OEM, IIRC. I do use OEM pads, though.
