Brake Squeal
So, one (or more) of my CCB brakes developed a squeal overnight. Not a high-pitched squeak, but more of an old school brake-dust type noise that only sounds off at the end of a deceleration, like below 10 miles per hour and can be controlled with modulation.. Zero scraping or grinding and the braking force is nice and even. Debris on a rotor maybe?
Any suggestions?

Check the outside brake pad thickness by looking through the wheel spokes. The inner pads wear a little faster but that is where the sensor is located and you can't see them without removing the wheels. If the outside pads have a lot of meat the inside pads will probably be sufficient thickness as the wear rate isn't that much faster. If nothing wrong with the pads then don't worry about it.

I would take it back. I don’t have CCB and mine are quiet as can be now. Good luck

Try washing the brakes or at least spraying them off with water real good then if the noise goes away it is the dust build up from the pads. Not sure it is the issue but on steel brakes it sure can be the stock pads put off so much dust it
causes the disc to squeal !

Carbon ceramics are known to squeal, not just on Corvettes. Burnishing can help but often times it comes back. It is a track oriented package with stiffer suspension and calibration. Google carbon ceramics squeal and spend hours reading about all the different makes and models experiencing the same thing.
