Brake Disc Pads Problems of Chevrolet Cobalt - part 2

Brakes failed, slid in the snow and hit the passenger rear rim against the curb. This even lead to the rim being replaced, along with the axle. After the car was fixed, I took the car back to the dealer where it was looked over too see if there were any manufacturer's defaults. Then I was told they could do nothing for me because they only had a 12 month/12,000 mi. Warranty, and my car was 17 months old and had 19,200 mi. I then replaced the rotors and pads around the entire car.

The car ate the rear brake pads and rotors in less than 16,000 miles which is odd!.

I noticed that the rear brake rotors were slightly scored when I got the car from the dealership new, I didn't think much of it since I was excited to get the car. They also make noise then applying the brakes. I've noticed to that some times after driving and parking, I can smell burning brake pad material. I currently have about 2500 miles on the car and the rotors have scored more considerably. I believe that the pads and rotors won't make it another 2500 miles without being replaced. After searching the internet I found that others are having this same issue with their cars. The car is a 2009 Chevrolet Cobalt ss sedan. I found that this issue affects the ss sedan and ss coupe alike. It would be nice if gm would issue a recall on this, as this could pose a potential safety issue down the road.

The rear rotors are grooved because of the faulty design and the pads are scoring the rotors.

I have a 2009 chevy Cobalt ss and the rear brakes are getting grooves in it bad. Only 1500 miles on it when it started. Pads have good amount left but they make this god awful squeal. Like they been driving on them for over 50000k but not even 10000k.

The rear brake rotors are showing deeper than normal grooves at less than 4000 miles. Pads showing premature wear. Front rotors are nice and smooth.

Rear brake issue on brand new 2008-2010 Cobalt ss the rear brake pads are overly hard to the rotor, causing heavy scouring and warping this is a known issue in the community for this vehicle and many gm dealers are not repairing the item under warranty, this item needs a recall.

Rear brakes on vehicle begin by squeaking regularly. Upon inspecting them at roughly 6000 miles on the brand new car, the inner brake pads are completely worn while the outer pads are nearly new (as they should be). One possible cause of this is that the parking brake spring is not strong enough to hold the inner pads from rubbing the rotors when the parking brake is disengaged. Gm should recall this brake issue as it will continue to cost buyers hundreds every few thousand miles, when all that is needed is likely a spring with a better spring rate.

Car had approximately 15,000 miles on it when the back brake pads wore out. Took the vehicle to my mechanic he said something was not right and I should take it to the dealer and get it fixed for free due to faulty install. Dealer assured me there was nothing wrong and charged me a 60 dollar diagnostic fee. Why would the back brake pads wear out before the front. . And why at 15,000 miles with conservative driving? something is clearly faulty with either the brake pads themselves or how they are being installed.

The inside brake pads on my 2009 Cobalt ss turbo chew up way too quickly. They wore out on the inside with less than a year of highway driving. They wear unevenly with the outside brake pads in the rear and the front brake pads, which are still the thickness of new.

2008 Chevrolet Cobalt ss rear brakes faulty. Rear pads are gouging in to rotors very badly at this point, 11,000 miles. I driver conservatively. This gouging of rotors actually became noticeable at only 3500 miles. I have owned the car since new. I recommend gm puts recall out on rear brakes for this car to replace rotors and pads free of charge.

2009 Cobalt ss. The inner rear brake pads are completely gone while the outer brake pads still have over 80% life left on it. Brought the car to rick hendrick chevy and the dealership refuse to fix it under warranty. They said it was normal. The car has 23k miles on it, just about all of that is high way miles. I drive the car normal and do no abuse it. Also want to state that the front brakes still have over 50% life left.

2008 Chevrolet Cobalt ss. Rear brake rotors badly grooved. Inner brake pad worn completely out. Outer pad worn to less than 50%. Front rotors have small grooves and have just under 40% of pad life left. Gm dealer would not fix under warranty but acknowledged that they didn't know why rear brakes are wearing before fronts. I have owned car since it was new. No racing just daily commuting to and from work (40miles one-way). Installed oem pads at 15000. Have seen problem progressively get worse since about 7000 miles. Current mileage approx. 32000,pads worn out in same manner as stated above and rotors are severely grooved, worn past safe refinish limits. Front pads are in ok shape and small grooves in rotors. 95% of driving is done on highway.

My Cobalt ss t/c has 9000 miles on it and I have been experiencing a very loud squeal coming from the front brakes since 5000 miles. Rotors were turned by dealership and pads replaced yet the squeal remains. A squeal so loud it can't be ignored yet gm states in a bulletin released recently that this is normal for high performance brakes. Gm needs to be held responsible for the hundreds of complaints of this braking system in recent months. Thank you.

Rear brakes are wearing down unusually fast, particularly on the inside surface where it is hard to see. Brake rotors are grooving severely. Dealer has resurfaced the rotors and sanded the pads once already less than 4000 miles ago, and now they will have to be replaced. Clearly, failing brakes is a serious issue.

The rear brakes on my 2009 Chevrolet Cobalt ss are failing at just 2400 miles on the odometer. The inner pads have worn down too quickly, causing excessive grooving on the rotors. This has decreased brakes performance vastly.

Rear brake pads on 2008 Cobalt ss have grooved in the rear brake rotors. Driver's side rear rotor is much more grooved in than passenger's, leading to my belief that brake pads are wearing unevenly in addition to scoring rotors. Problem has occurred with many other owners, see Cobaltss. Net/forums. When vehicle was brought in to gm dealer, service manager informed me that wearing was "natural", and that I should bring the vehicle back in at 15000 miles.

Rear brakes are gouging and wearing at an alarming rate. At 15k miles I am about due to replace the pads and rotors in fear that they will fail. I had them inspected at 1900 miles when the problem first occurred, dealer stated it was normal wear. Dealer denied me warranty coverage due to only a 12k warranty on the brakes.

The rear brakes of my 2009 Chevrolet Cobalt ss are worn down the metal after approx. 15 000km. The inside pads was metal on metal, and the out side pads were found to be still 80%. All parts are being covered under warranty, but many people have had the same problem after all parts were replaced. Rear brake pads and rotors are being replaced.

Brake pads wear at an extraordinary rate. They have also gouged the rotors. This is on a brand new 2009 chevy Cobalt ss, less than 9000 miles on the car (purchased in April). The brakes continually squeak, and have done so since I picked up the car. The dealership explained it was a "break-in" period, but clearly it shouldn't last this long. The squealing, in addition to being annoying, may pose a safety risk due to the accelerated pace at which they brake system wears. I noticed after a car/wheel wash, the noise dissipates, but returns soon thereafter. I'm concerned about the longevity of the brake system.

Rear brakes: inner pads metal on metal, outer pads still plenty of life left at 17,500 miles. Reported brake squeal/grinding by 4,000 miles, had parking brake re-adjusted at that time.

Rear brakes having pre mature wear of the inner pads and severe gouging of the rotors. Outer pad was 75% worn and inner pad was 98% worn at 10k miles.

2008 Cobalt ss rear brakes are wearing prematurely and rotors badly grooved. Rotors were turned at approx 7000 miles. Now at 23000 miles and inner brake pads are down to metal and rotors are once again badly grooved.

At 6000 miles, my rear brakes are completely worn down, my rotors are scored, and one gm dealer said they would warranty my rotors if I purchased new pads for over $100, and another dealer said that the wear was "normal" for my car. This obviously is a manufacturer defect, and I am not very happy. The dealer said I have over 75% life left on the pads through his gauge system, and yet it makes horrible screeching noises. The rotors are scored very badly.

1. Car is a daily driver, so no abuse or anything. 2. Rear brakes are squealing again after being replaced once (pads and rotors replaced by dealership) 3. The rotors and pads have been replaced once, but it's happening again.

I have a 09ss/tc and I have a problem with my back rotors with lines and grooves in them. I only have 4000 miles on my car now. I took it to the dealership at 3500 and the shop manager argued with me that it is normal wear and tear and that the back brakes are "aggressive" style pads. And he argued that the back do more stopping power than the front. They haven't done anything about this problem yet and I know that many other cars of the same model have this problem. The main mechanic did confirm that it isn't a normal wear but said that the car is too new to anything about it. Please help us out I really don't want this to cause an accident or for me to have to pay for all new rotors and pads at my expense because of their mess up.

Rear brakes and rotors exhibit excessive wear. Rotors grooved and pads worn on inside of rotors only. Finally had rotors and pads replaced @ 19,800 miles.

Wearing of rear brakes. This includes deep scoring of the rotor and brake pad as well as loud grinding when stopping. This has been ongoing since 100 miles. I am now at 5k miles and have seen a few cars with the same problem. Pads and rotors need to be replaced and an alignment done.

My rear brakes on my 2009 Cobalt ss with just over 17000 miles on it were completely gone when I took the car to the dealership on Tuesday July 28th of 2009. I first noticed some unusual noise coming from the rear of the vehicle at around 15000 miles. At first the noise was sporadic and I was not concerned with it but it soon developed into a constant friction type noise that could not be ignored. After leaving the vehicle with the dealership all day they found the cause of the problem. My rear brakes were metal to metal with the rotors. The service employee asked me if I e-brake slide the car, since I was not exactly familiar with the term he had to clarify its meaning. I told him I am not an e-brake sliding kind of guy and asked him to check the ware on the tires if he did not believe me because it sounds like performing a maneuver like that would cause the tires to have bald spots. We the service people could not find any bald spots they ruled the brake as a defect and covered them under warranty. I just find it unusual that the rear brakes would do this so early in the life of the vehicle when the front brakes look like they have barely been touched. If I had been taking a turn or having to brake in an emergency I dont know what all could have happened when I have rear metal to metal instead of the oem brake pads to protect me.

Rear brakes wear very rapidly. The rear brake pads were completely gone within 14k miles, rear rotors scored so heavily they needed to be replaced. 10k miles later the replacement brakes are almost gone. Not covered under warranty. The front brakes have been fine this entire time - still plenty of life left.

Rear brakes on 2008 chevy Cobalt ss, wear rapidly causing destruction of the rotors and excessive stress on the front brakes. Replaced under warranty the first time at ~12,000 miles. Rear pads completely shot again at ~22,000 miles. This time, the dealership wouldn't cover it. The extended abuse to the rear brake system cause abnormal noise from the rear during low speeds.

The rear brakes on the 2008-9 Cobalt ss are causing rotor scoring at 400+ miles. The pads are too aggressive or the rotors are too soft and the rotors are being destroyed which could lead to brake failure if not replaced.

Brake pad failure: at routine service, 17,665 miles, dealer found rear, inner brake pads excessively worn. Right pad was gone, rotor being scored. Left was less than 5% remaining. Other pads within normal limits. Replacement pads are not in stock at gm, back-ordered.

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.
