If I turn while braking, especially right hand 90 degree turns (into driveway, etc) I get a loud scraping noise that seems to come from the rear. Only if I've slowed down to less than 3 or 4 mph will I avoid it.

I've only noticed this since I put on my winter wheels but I don't know if that's the cause. I've got 215/55/16's on and there doesn't seem to be any clearance issues.

Has anyone else experienced this?

 

I bet your tire is rubbing on the plastic thing that goes over the wheel well

 

That's what I was thinking, but why would it happen only on turns? It hasn't happend during hard braking nor hard acceleration (which is all the time ) You think the sidewalls of the tires are flexing that much on turns? I guess I'll have to take a wheel off to try to see if there are any scrape marks.

 

I have a similar problem its a repetitive rubbing noise when im turning slowly. Its very random, so im going to see if my wonderful dealer can figure it out this week.

 

Droped my car off at the dealer this morning, and they call me back an hour later to let me know that my drivers side rear caliper is hanging up and they have to order a new one. also they think this is what is making my car pull to the left. So we will see if this fixes everything.

 

i've had something like that as well, sounded metallic, and i've noticed it most commonly when doing hard braking from high speeds (100mph+) but not always when i'm turning.. usually goes away after a few minutes.. i dont really wanna ask my dealer about about it, cant give away that i've been driving the car that hard.

 

had a simliar noise when i was braking, dealer, got the rotors refinished, noise gone. just a thought

 

thats what they originally though was the problem. Funny thing is they did it to my front rotors and it turned out to be the rear brakes that were the problem. YAY for GM SERVICE!

 

Got the car back finally with two brand new rear calipers. We will see if this fixes the problem.

 

i have the same problem/noise. always after heavy braking, coming from both rear brakes i think, gota take to the dealer. i think they must be hanging up as well, although ive never seen any extra wear or dust, or smell hot brakes. anybody else have this after heavy braking??

 

I have hanging rear calipers for sure. I always smell hot brakes, hard driving or not. The dealer inspected them at the beginning of winter and said everything was operating normally, at my next oil change I'm sure they'll notice the extra pad wear in back!

 

My noise comes from the flimsy plastic end piece that encapsulates the rear of the car. Press on it sometime just behind the rear wheel and watch the wheel well move nicely along with it. Needs braceing of some kind on each side.

 

does this rub on tire? i have not noticed any rub marks on mine, but cant really see in there that good either.....
