I first thought it was suspension related but after two trips to the dealership they couldn't find where it was coming from. I finally realized it is very likely the brake pads knocking around since slight pressure on the brake pedal makes it stop. I brought it back to the dealership again and explained this to them only to be told it's normal for CCB's to make some noise. Well, not this noise. When I bring it back in for it's break in I'm going to push for pad and/or bracket replacement.

I experience this exact thing on the CSL. Please keep us posted on the findings.
