Squeaking PCCBs
#5
This raises question do these brakes require bedding ?..I had to bed my carbon ceramic brakes on my ZR1...ended up heating the hell out of them with no noticeable performance gain..brakes got so hot the pads turned white and the wheels temporarily turned blue (cleaned off)..this procedure completed as per owners manual

CCB's generally have a specific 'burnishing' procedure that needs to be carried out in order for the rotors and pads to work together for maximum effectiveness. It will also markedly decrease the tendency towards 'squealing'. Look for it in the owner's manual.
You can also try multiple stops from around 80mph down to 5 mph; this normally helps also. Just don't engage the ABS.

Just to clarify the car has 22k miles and they've never squeaked or squealed before. I was thinking maybe it was a sign of them wearing out. I've never tracked it but do drive aggressively regularly. I will try some long stops and see if that works.

If you don't track the car, and if the rotors don't get physically damaged they should last the life of the car essentially. Not the pads; just the rotors.
The stops need to be from high speed down to a low speed of 5-10 mph in as short a time as possible, but without engaging the ABS. Do 4-5 of those and then drive around for a few minutes without touching the brakes to allow everything to cool down.

It can get annoying. I haven't experienced any squeaking in my 991 but it only has 4K miles.My 997.2 squeaked after 25k miles and a pad change. After doing a bed-in procedure it tends to go away. But I still get random squeaks. It's rare now but maybe an attribute of higher mileage PCCBs.

the burn in didn't change anything. still squeaking. mostly I notice it when the car is cold, although it hasn't been that cold out. but I hear it a lot more when I first start up and am pulling out of a parking lot or driveway, etc. I don't notice it after a drive when I'm pulling into somewhere, but that could just be not paying as much attention to it.
