2008 Chevrolet Cobalt SS: grinding or squealing brakes

Filed May 25, 2011 · Brakes · VT

Bought my cobalt ss new from dealer, with less then 5,000 miles rear brakes were squealing and very obnoxious. Upon inspecting and bringing the car to the dealership was told that my brakes had gouges in them and needed to be refinished and cleaned as well as new pads installed. This was not covered under the warranty as they said it was wear and tear and the noise was normal.

Under normal daily driving conditions (majority is commuting), my rear rotors and brakr pads were replaced at 21,259km, quote from service order from my dealership, "rear brakes at squealers, confirmed squeal noise from rear. Found rear brake pads at squealers. Both rotors badlyscored. Machined rotors lr19.0mm and rr19.10mm replaced rear brake pads". Then at 42,465km brought vehicle to dealership as I could smell burning brakes from the rear end after only 20 min of daily average driving . Following is a quote from my dealership work order, "cause: seized/binds/sticks. Found rear brakes @ 2mm remaining on rear inboard pad. Checked complete hydraulic sys. Checked for ABS codes. Checked for bulletins on rear brakes. Checked e brake no problems found. Removed rear calipers and found calipers sticky. Need to be replaced both rear calipers sticky. Need to replace both rear calipers, rotors and pads. Inner pads 2mm outboard 6mm and rotors undr min. Replaced both rear calipers, rotors and brake pads. Bled brake system". Then my dealership followed with "this will be the last time gm will replace rear brakes". As far as I am concerned if the rear brakes are inadequate fro the application and are being worn out and damaging brake parts every 20,000km or so then a recall needs to be done with replacements of an adequate breaking components.

The rear brakes on the chevrolet cobalt ss are pure crap. They squeal pretty badly when you come to a stop, no matter if it's a fast stop or a slow stop. It gets even louder when they get hot. I've taken to my car to the dealer since my 08 cobalt is still under warranty and they've told me that high performance brakes are supposed to be loud...I'm sorry gm, but not this loud! So they rotated my rotors, and gave me new brakes about a month ago, and it's still as bad as when I got the car back in april of this year.

I own a 2008 chevy cobalt ss. The rear brake pads were wearing out very quickly and damaging the rotors. First noticed a grinding noise on the rear brakes at 950 miles and now at 16,500 miles, I am sitting at the dealer service dept. Being told that my pads and rotors need to be replaced. The previous dealer ignored my requests to have this corrected before it got this bad. This dealer looked at it and they said that the car is not safe to drive until the brakes are replaced. So I am waiting to see if they will repair it or give me a loaner until it can be repaired. *tr updated 02/02/10 *bf updated 02/05/10

Since I purchased my 08 cobalt ss, I noticed the brakes made noises and the rear brakes wore funny. Brought it to the dealer where they deemed this "normal for these brake pads." at 19,000 miles I already needed new rear brakes as the dealer said they were "grinding against the metal" and my rotors needed to be resurfaced. Something has to be done about this as putting a new pad on does not fix the problem and I will only need new pads and rotors in another 15,000 miles or so.
