Brakes Squeaking
I have a Z06 (Non Z07), not ceramic brakes.
Brakes are squeaky under light braking. Anybody else seeing this?
Never had it on the Stingray…

Just take it out to a safe place and do 5 stops from 60-20 progressively harder stops without getting into the ABS, then drive with minimal brakes for 10 minutes. This is a very common problem and solution for performance brakes.

It is easier to do 90-30.....................
But, use the brakes hard but with sensitivity,
if the window is down you can smell when the pads are properly hot.
And don't *****-foot around on acceleration.
Use a road with low constabulary vision.

Good ideas above; additionally brake squeal can be caused by accumulated brake dust in and around calipers, rotors. Compressed air with a tip nozzle while not solving all squealing especially again if not bedded in properly, will for quite a while solve many squeal issues.

The CCB's will definitely get rid of most the dust, BUT they squeal even more than the iron brakes. If squealing is your biggest complaint/ annoyance, I'd rethink that decision.

After 1200 miles, my Z06 brakes are still quiet, but so were my Z51 brakes at this point.

Interesting. My 458 didn't squeal. They were a bit grabby at slow speed and not very good when cold.

Try the 70 mph to 20 mph hard on the brakes but try not to activate the ABS. Drive a few minutes at highway speeds between braking events. I did it up in the seven lake area in the quiet season and no one is around so it’s a nice safe area to do this and the scenery is nice too boot.
Shouldn’t take more than a half an hour at most and it solved the issue on my c8 z51 and I also had brake pulsation issues that went away too.
I think it’s the environmentally friendly pad material.
(edit) and don’t spray wheel cleaner on the wheels. I now just use a separate bucket of car wash soap.

Common With Performance Brakes
From years of using different brake pads on my C5 and C7 Corvettes I can say good pads on iron brake rotors make dust and noise.
You can get rid of the dust and noise with different pads, but will sacrifice braking performance. Race pads are another level, they coat the wheels with dust in a few minutes and squeal and groan like a garbage truck when cold.
The reason bedding helps is that the hard stops and heat, transfer pad material to the rotor which makes them work better. Subsequent normal street driving does not get the brakes up to temperature and will wear the transferred film off the rotors, and the noise will return.
Brake grease and/or fiber shims between the pads and caliper pistons can help but are not foolproof.
My new Z06 will be my first experience with CCB so I can’t speak to those yet.
Performance brakes making noise when cold IS normal. Squealing brakes are a badge of honor with performance cars. They go with the loud exhaust.

With any brake setup, rotors need to have a thin layer of brake pad material for ideal performance. Whenever the vehicle sits under moist conditions, there might be a think layer of rust on the rotor or any other foreign material which results in this noise, This noise should go away a few brake applications during regular driving.
Any brake development has three major goals - Performance, NVH and Cost. For performance vehicles, cost and NVH takes a back seat since the performance targets are really aggressive and as a result this phenomenon is very common with high performance vehicles.

The goal is to keep the pads bedded. That takes some aggressive use at times in a controlled fashion.
But they still may squeal. They are performance brakes and that is what they do. They also dust.
Ceramic replacements are available now or soon for the iron brake cars.
