My rear brakes on my 09 cobalt ss are wearing unevenly. My right side rear brake pads are completely used up and as a result have begun to grind on to the rotors and caused them to form pits, and or grooves. Very disappointing.

This has been an ongoing problem for over a year now. I take my vehicle to the dealer and tell them the rear brakes are locking up and they respond with "this is caused by driver abuse, you have been powersliding it" I have had it to three different dealers. The rear brakes have been replaced 3 times within 9 months and are now needed again. Chevrolet states they are not willing to fix the problem.
2009 chevy cobalt ss turbo rear rotors scored badly driver side, inner rotor scored worse, 6,700 miles on the vehicle pads screech also at a stop.
Bought my 09 cobalt ss tc sedan with 3500 miles on it. Rear rotors already had grooves at that mileage. My car is at 8700 miles now with both rear brake calipers having to be replaced along with deeper grooves in rear rotors and squeaking from the rear brakes. The failing rear brakes caused my emergency brake to fail. The emergency brake failed while on a hill and I walk outside to find my car under my girlfriends truck! (e-brake engaged and in reverse) this was fixed with the calipers being replaced, I still need to have my rotors worked as they are already to this point. I was fortunate to be parked on a not so steep of a hill, couldn't imagine someone in the same situation living in a hilly region. (lawsuit waiting to happen).
Premature rear brake rotor wear.
Normal driving lead up to the extremely premature failure of the rear rotors and brake pads, increasing stopping distances which could result in a crash. I took my car to the chevrolet dealer and, though at only 25,000 miles, they said I needed to *replace*, not resurface the rotors. 25k miles! To remedy the problem, I had to find and purchase higher-quality rotors and brake pads and had to pay to get them installed. I believe this surprising and extraordinarily early failure--even though it may fall under "maintenance"-- should be investigated.
I have a 2009 cobalt ss. The rear brake rotors started scoring around 5,000 miles and and rear pads were completely worn away with 19,800 miles.
2009 chevrolet cobalt ss, rear brake disc heavy scored , grooved,cupped especially inside of discs. 13,000 miles on car and dealer said tough luck not covered under warranty and they haven't heard about it before. That's a flat out lie, I also have an official complaint logged with gm, they called me back with a reference number and said they would look into it but have not heard back in over a week now. There is a major safety issue going on here and they do know about it. Either the metal of disc is incorrect or pads are not compatible or defective calipers- hydraulic system.
Rear brakes make scratching sounds and the inside of both rear rotors have been scored deeply this was noticed at 5000 miles when I bought the car and has got much worse at 17,000 miles. Also took it to my dealer and the would not replace anything.
Inside rear brake pads completely worn through at around 20,000 miles. Dealer would not cover brakes so new aftermarket pads were purchased and installed.
Rear brake rotors scored horribly with only 10k miles.
Tl*the contact owns a 2009 chevrolet cobalt ss. While driving approximately 35 MPH pressure was applied to the brake pedal the contact heard a grinding noise. The vehicle was taken to an authorized dealer who stated that the failure was due to excessive braking. The dealer also confirmed that the rear rotors and brake pads needed to be replaced. The vehicle was not repaired. The failure and current mileages were 21,000.
I just bought a 2009 cobalt ss that only has 3289 miles on it and the rear brakes are already going bad, and the rear rotors are getting deep gouges. This could be a very bad problem. Would hate to see this turn into another toyota thing specially when the ss is such a great car. I think a recall should be done and better rotors and pads should be put on the ss cobalt.
My car has only 11,000 miles on it and the rear are brakes are warped, which in turn causes my car to not stop as fast it should. The rotors are all warped and the pads are very cheap. I called gm and they told me that the brakes are covered to 12,000 miles, but only 12 months. It's been 14 months and they won't even help me out. This problem occurs very often and I am afraid I am going to get into an accident.
A terrible grinding coming from rear brakes. The brakes wear out too quickly (and the rotors are being scored at 100mile-20,000mile cars) also inside rear pads start to get noisy.
Premature rear brake wear.
The stock rotors on my car started getting severely warped within the first 3-4 months of owning the car. The car was brand new when I purchases it. I replaced the brakes after owning the car for 10 months and the car had about 14,000 miles. I showed the dealer the rotors and they resurfaced them. I've been driving the car with new brakes since june 2010, the new brakes are already squeaking and rotors have severe grooves on them. I purchased the car june 2009 brand new.
Uneven and excessive wear on the rear brake pads and rotors. When the dealership pulled the pads there where chunks of metal that appeared to be rotor material embedded in the pads.
I bought a 2009 chevy cobalt ss used with 9000 miles on it. From the day I bought it I consistently heard rear brake noise whenever I stopped the car. There is excessive pad wear on the rear brakes at 11000 miles now. Way too much wear than normal. Deep scoring in the rotors. Took the car to the dealership I purchased it from and they resurfaced the rotors but the problem was still there after I drove the car home from the shop. So far nothing has been done to correct this problem by the dealership of chevy.
Have 2009 chevy cobalt ss and has had to turn my rear rotors for the 5th time since I got this car brand new, at 36,000 miles now.
My vehicle is a 2009 chevrolet cobalt ss coupe purchased new in march of 2009. After 15,000 miles (about a year's worth of driving), the rear brake rotors were pitted and scored, and when the brakes were applied a metal-on-metal grinding noise would occur. Also, after getting wet from driving in the rain, then allowing to vehicle to rest for a short period of time, enough rust would build up on the rear brakes that a copious amount of throttle would be needed to break free the pads from the rotors to move the vehicle forward. After taking the car to the selling dealer for inspection/repair, I was told this part was a wearable item and not covered under my manufacturer's warranty. I explained that most all owners of cobalt ss models between the 2008 - 2010 model years were experiencing similar rear brake issues, but was told that did not matter. The parts were not covered under warranty, and if I would like them repaired/replaced, I would have to pay for the parts and labor.
Purchased car brand new, have approx 10k miles on it. Rear brake calipers seem to not release fully- can be heard grinding when reversing and screeching when gently braking while moving forward. Rear brake pads are wearing unevenly so that the outside pad is scoring the rotor and wearing much faster than the inside. Possible that the slider pins on the caliper are not lubricated? I've had my local chevy dealership where I purchased the vehicle look at it, they wrote it off as brakes being a "wear&tear" item. Rear brakes only account for 20% or less of the full braking of the vehicle. Why is it that my front brakes are fine and my rears almost need to be replaced already?
Front & rear rotors scored severely with deep grooves throughout. The car has less than 12,000 miles. Braking is severely hindered during wet conditions and periodically the brakes are noising making "screeching" sounds as though metal to metal is touching during braking. Problem is most likely due to brake pads being far to hard of a material causing excessive wear on the rotors.
I purchased a new 2009 chevrolet cobalt ss sedan. The car has barely broken 10k miles. The brakes are wearing abnormally fast. I am very gentle with them always, and they are very worn already. Pulling up to stop signs or traffic lights is ridiculous. The screeching from the brakes is loud. I have never had brakes go out this early on any of my other vehicles.
Had to replace rear brakes on 2009 cobalt ss after ~ 12000 miles. Rotors had to be replaced. Made very noticeable screeching and grinding sounds. Brake performance had decreased very much even before they were replaced, decrease in performance of brakes at about ~7000-8000 miles.
I have a 2009 cobalt ss that I bought new and before I had the first oil change at 5000 miles I was having brake squealing the dealer looked at it and said its normal iv had it at 2 different dealers several times and nothing has been done, I now have 26000 mile and no back brakes rotors are badly scorn, something has too be done with this.
With just over five thousand miles on the car the rear brake pads are grinding. The of the rear rotors has deep grooves. When it is wet its extremely hard to stop. I almost hit the vehicle in front of me when I was on an exit ramp because the vehicle wouldn't stop.
Bought my 09 cobalt ss with less than 1,000 miles and my rear brakes squeal and grind horribly with only 11,500 miles.
Had tires rotated at dealer, they found rear brake pads worn out completely and rotor scored after only 6000 miles. Have found many other owners with same problem. Dealer claims it was caused by driving with the e brake on. They refused to repair unless paid, claims warranty does not cover pads wearing out unusually too soon.
While driving down the highway, doing approximately 60 MPH, my 2009 chevrolet cobalt ss shed it's inner left rear brake pad, causing the brake pedal to sink to the floor, when pressed, to no avail. Luckily, no accident resulted. Upon inspection, the left inner pad was completely gone, while the left outer, and both right rear pads were well within normal limits. The gm dealership refused to fix this problem, stating that it was "normal wear and tear". A mechanic at the dealer whispered to me that it was a failure that was likely caused by the caliper not retracting properly, and, while it should be covered under warranty, there was nothing he could do. This failure occurred at about 12,000 miles, while the vehicle was only 4 months old. The rear brake pads, as well as, the left rear rotor had to be replaced.
