All,
I have notice my SL550 has more brake dust and rotor wear than front which doesn't make sense to me. My front rotor looks great not much wear no lip or anything but the rear rotor has much more than front. It generates more brake dust then front as well. Anybody has same experience? Any idea will be greatly appreciated!

Change to ceramic pads with new stock rotors. That will eliminate any brake dust problems and give you better brakeing. I just did this and I also noticed that the rears were creating more dust than the fronts prior to the change. The whole job should be about $500. Use the Akebono pads.

My fronts always have considerably more brake dust than the rears.

I actually ordered Akebono pads last week and fixing to change both front and rear brake pads. I guess I need to order rear rotors. Any suggestion on good cross drilled rear rotors?
The wear on those rear rotors kind of surprise me. Any thoughts there might be some issue with adjustment ratio between front and rear. I thought front should always more brake dust as it should wear more than rear. My case just the opposite.

The stock rotors are fine unless you plan to put the car on a track. Stock fronts are drilled but the rears are solid. After changing the pads and rotors there is almost no dust on either the front or rear.

Yes, my front is drilled and rear is solid. I was hoping if I can get drilled rotors to match the front. Do you mind if I ask how much dealer charge for rear rotors?

Stock rotors are about $90 each. There are some after market rotors available. Do a search in this forum to find a recommendation.

The harder the compound the more wear/friction thus dust - I like to replace pads versus spending substantially more on rotors, again just me.

On consumer vehicles (and most race vehicles) the brakes are used more on the front wheels than the rear. This greatly enhances stability and control under moderate to severe braking. If your braking was more rear-biased, then the car would want to enter corners rear-end first due to the rear wheels stopping better than the fronts. Hence, the front wheels will always have more brake dust on them than the rears.

If you are trying to get rid of the brake dust, then switch to ceramic brake pads. Anecdotal evidence has shown that you could wear down your rotors more quickly than with the OEM pads. Just something to consider -- there's always a trade-off.

Ordered lowering link, rear rotors and Akebono brake pad for front and rear. Hopefully I will get them next week!

The SBC system does not function as others have described in some of the posts above. I like they thought the same thing but was corrected by the attached pdf supplied to me by a mechanic whom I'm on a first name basis with at the dealership. As you can see from the pdf, the system is NOT setup like non-SBC systems. I asked why I needed rear brakes when he told me they were worn but the front were fine. He laughed and said until he was trained on the operation of SBC he didn't understand it either. See attached pdf explaining SBC operation.
