My 2012 Grand Sport with 9K miles on it has brakes that squeal pretty much every time,anyone else have this problem,I have taken it back to the dealer 5 times and they give me a different reason every time,once they told me to speed up to 50 mph and stomp the brakes.what are my options?

Well known problem with the C6 all iterations. Only thing to do is replace pads with non metallic to reduce noise and dust.

Actually, speeding up to 50 and stomping on the brakes will fix the problem but probably only temporarily.

Ceramic pads will quell the noise and dust the dust. At least it did for me.

Your far from alone on this subject as many Grand Sport owners have complained about this issue. My '13 GS took about 4-5k miles from new to start squealing. I took it to the dealer and they replaced the pads under warranty. 5k miles later it came back. About 6 months ago with 17k on the clock now I took it back again. The dealer said GM has this new anti squeal paste that they put on the pad surface to stop the squealing and the service manager said it works very well. So they do that under warranty and it lasts all of one week! So now I'm going to just put ceramics on and see what happens.

I have 14k on my GS and have never heard one squeak from the pads, then again I do use the brakes like they were designed. Driving a track capable pad like your grandpa's Cadillac will always result in squealing, use the car the way it was intended to be and you will be fine.

Pads on my GS started squeaking slightly last summer at 23,000 miles. Just put fresh OE (semi-metallic) paddlets on, did the bed in procedure and it's all good.

Before you go to the expense of replacing your pads which have relatively low mileage on them, pull the calipers & try coating the rear of each pad with a THIN coat of hi-temp grease. In some cases, the squeal is caused by high frequency oscillation of the pad itself in the caliper & the grease tends to damp that oscillation. I do that whenever I change pads in all my vehicles & never have had any noise problems from the brakes. Just be careful not to get grease on the front side of the pads or the rotors.

Thanks much guys

This worked for me.

HOXXOH

Yep, and then you can do it again and again and again everytime it starts squealing.

Hey, watch it buddy! I'm a grandpa (even greatgrandpa) and I drive my Caddy almost as hard as the Vette. My brakes never squeak.
Now before you go picking on grandmas, let me warn you about my wife.

Clean the calipers...
The chrome slides which the pads ride on, take them out and hit them with a toothbrush and when they are shiney again, apply a light coat of high temp grease.
Hit the pistons with a toothbrush and try to get some of that black brake dust out of there.
Put a light coat of high temp grease on the back of the pads where they touch the piston.
Pull the caliper slide pins out and clean them if they look ruff from water damage, try to polish them with some 00 steel wool. If they are too pitted replace them and the rubber seals. Then reinstall with high temp grease.
You can stop the squealing without racing your car.
Usually, a squeal is something just not lining up properly.

While you are doing this think about ceramic pads. They not only keep the wheels clean but keep the inside of the calipers cleaner.

With a little time, you can make the squeal go away.

Though I am not as old as Grandpa in the post above...

My Cadillac ATS 2.0T brakes have never squeaked.

When I said Cadillac I was thinking of the old ones. If I even think about turning in my DeVille it starts to scream.
The newer ones ? Much better. Maybe I should have said Lincolin instead.
