I was wondering if anyone else is having problems with brake squeaking. I have a 2011 Grand Sport with about 20K miles and getting a lot of brake squeal. I took it into my dealer and they have a good Corvette mechanic who told me that the cross drilled rotors are plugged up with debris and that's what is causing the noise. He said the only way to remove the debris is to remove the rotors and clean them. Cost about $450. I'm just wondering is anyone else has this problem or if anyone thinks there is a way to silence my brakes.

Stay far away from that dealer! Yikes!
There are lots of things that can contribute to the squeal. I just installed new ceramic pads on my 05 and was getting squeal. I corrected it this evening by lubricating the shims/guides and pins with brake grease.
If ceramic pads are available for the GS, you may want to consider switching over to those since they are much less prone to brake squealing. Good luck!

Just too many other possibilities for the cause of the squeal. I would not spend $450 on a "first guess" from one mechanic. That could get really expensive to keep trying fixes if his first guess is not right. Get a second opinion from a brake expert mechanic rather than a Corvette mechanic.

I fixed mine, stock Z51 pads with a little caliper grease behind pads where they contact pistons. quiet ever since.

Wow! $450? Sounds Like Highway Robbery To Me. Mine Squeak Occasionally, I Just Turn The Radio Up

My dealer told me brake dust. Cleaned them. Twice. Still squeak. I turn up radio.

I run ceramic pads and they squeak when I apply light pressure when I apply more pressure to stop the car it goes away. I think it is the pad material, I've had the breaks apart and there is nothing wrong that I can see. Just push down on the pedal a little harder.

Thanks for the all the replies. mine also only squeak when lightly applied. Problem is sometimes you have to just lightly apply them. Might try taking them to a brake expert.

Mine squeal too. (I have an 08 Coupe, but put Z06 brakes on, which are the exact same as the Grand Sport)
They don't squeal all the time, but enough to be highly annoying. You aren't alone.

I bought a set of Hawk HPS pads in Carlisle but haven't had a chance to install them yet. They are supposed to be quiter and less brake dust as well. Hate having to replace the pads which still have plenty of life in them, but the noise is annoying, and embarrassing at times too.

That's a new one....pad material in the holes Yeah, it builds up in there but it's not the squeak.

Typically the pads squeak because they've worn the pins.
- Pull the padlets
- Clean the pins and padlets with brake cleaner (don't spray the cleaner on the caliper decals, some types will remove them)
- Apply a light coat of brake grease to the pins where the padlets rest on them
- If the backside of the padlets look worn and/or shiny, apply Disk Brake Quiet (I like CRC) per the directions...

Good to go

Depending on usage, at 20k miles it may be that you need new pads. At 10k miles I'm on my third set (due to multiple track days )

Gads, and I thought I was the only one w/ noisy, embarassing brakes. Decided to switch to ceramics(originals still had plenty of life on 'em). Now just a slight squeak upon braking, but disappears when more pressure is applied.

I had the same problem with my 2011 GS. (I now have a 2012 and the problem is much reduced.) My dealer's dedicated Vette mechanic printed out and gave me a copy of the GM advisory about the fact that these brakes squeal, and that's the way it is; he did not try to sell me on any fixes costing anything. The mechanic the OP spoke with might not have checked or known about the advisory -- both important deficiencies in a mechanic. OP, if I were you, I would ask if there are any GM advisories on this and whether they read them. Either way, it appears that the OP's mechanic -- or that dealership -- is not "Corvette friendly".

hmmmm....2011 with 20k miles.....wouldn't your vehicle still be under warranty.....

boraxman

Should be..Good call

CorVetteJones

it is still under warrantee but I was told since this is normal wear it's not covered. I think the mechanic that I talked to is pretty good. There may be a service bulletin that he knows about but also knows there's no fix. He probably thinks cleaning is a potential fix. Greasing the back of the pads seems like a reasonable fix. I'll have to think about that.

It's not grease on the back of the pads, it's a coating. The brake grease only goes on the pins. You can also put the grease on the wear points where the padlets sit in the anti-rattle clips.

Brake pad squeal on the C6 is normal due to the high performance pads used on the car. You can change over to ceramic pads or you can chamfer the edges of your pads. Some copper grease on the back of the pads and the pins might help also.

The mechanic that told you the problem is the clogged holes in the rotors is just trying to make a boat payment.
