Easy solution for me.
Yes this is a well-known issue with Z51 cars. And not just the C8.
My solution to the problem which always seems to happen when the weather is really dry, is to put a high pressure stream from a garden hose to the calipers and rotors to wash the loose dust off. That is what makes the squealing sound. Should be good for some driving afterwards till u have to repeat the process. Works for some cars, not for others, so it is a hit and miss strategy.
You may also notice that when the weather is wet, no brake squeal. Because dust is washed off by rain as you drive. For you pussies that drive only in dry, you will have more squeal.
