I posted in the performance section as well, I hate to repost but I'm hoping for any suggestions here as I really need help.
So I bought a GS zo7 and when I did they installed new ceramic pads on it. I've never owned ceramics and didnt know i had to break them in. 500 miles into owning her and they are squealing like crazy up front. The rears are fine but you can tell from looking at them the fronts are tough. I'll add a picture.
Please someone tell me a fix that doesnt include replacing them. I've got quotes around 5k for the fronts and cant really swing that right now, it's also my daily driver so I need it for daily use. I've heard resurfacing but I've also heard that these are impossible to do. Any suggestions needed!
I'm taking her out to the desert to try to burnish them if its not too late as I'm in LA and theres nowhere else to do it.
It could be that wrong type material pads installed? I would stick with OEM GM (23316708)
Street High Performance Brake Burnishing Procedure (Z06 with
Z07 Performance Package or Z06
with J57 Ceramic Brakes)
1. From a stop, accelerate as
rapidly as possible without
activating traction control to a
speed of 100 km/h (60 mph).
2. Use enough pedal force to
completely stop the vehicle in
four to five seconds. If ABS
activates, braking is too hard.
3. Repeat Steps 1 and 2 – 50
times. This should take about
10 minutes.
4. After completing the 50 stops,
cool the brakes by driving for
8 km (5 mi) at 100 km/h
(60 mph).
Racing/Track Brake Burnishing
Procedure (Z06 with Z07
Performance Package or Z06 with
J57 Ceramic Brakes)
This procedure should only be run
on a track and only on dry
pavement.
Caution
Brake pedal fade will occur during
this track burnish procedure and
can cause brake pedal travel and
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
1. Drive a normal first lap, not too
aggressively.
2. Laps 2 and 3 should be
gradually driven faster and
more aggressively, while
allowing for reduced brake
output and increased stopping
distance due to brake fade.
3. Drive Lap 4 near full speed,
while allowing for reduced
brake output and increased
stopping distance due to
brake fade.
4. Laps 5 and 6 should be cool
down laps.
5. Lap 7 should be normal driving
or an easy out lap.

Reason: grammar
Thanks! I just went by an LAPD office to find out where I can do this without getting a ticket lol. They are going to setup a road block on an industrial road Saturday night at midnight to do it. It's right off the highway so I can hop on after and cool em down. Pretty awesome of them to do this. I'm just worried my rotors are too far gone. I checked the service records they are "track" ceramic pads used at the Corvette racing school so I think we're good on that. I made about 5 runs for fun doing it and damn can you smell the brakes! Freaked me out a bit lol.
I'll update everyone after.
Before you do anything confirm the correct pads were installed. Ceramic rotors require specific compound and are unique to CCBs, “regular” ceramic pads will increase rotor wear.
While I haven’t experienced any noise from my Z07, CCBs are known to be noisy.
I haven’t burnished my brakes, but if you proceed do it carefully. People have reported that being too aggressive led to discolored calipers.
I think you'll get it right eventually. What impresses me most is: you got WHO to do WHAT? The LAPD? I can barely imagine a very rural state police office, or local police department doing something like blocking off a seldom used side road for this, even at midnight. Are you a LAPD-known billionaire contributor to the department's sports league?

Z07 rotor help!
Good luck getting this sorted.
