| I have noticed excessive wear on my rear brakes and groves forming on my rotors too. i have a 2008 chevy cobalt ss turbo. the dealer is saying it is normal wear and tear but i believe it is something more than wear and tear. my complaints to the dealer has gone unheard and will not be addressed. | |||

| 1. before purchasing this vehicle new in 2008, i was made aware of an issue with the rear brake wearing abnormally. i had made at least two inquiries to the service department at the dealership about the possibility of a tsb (technical service bulletin) being released on the problem. at the time there had not been, but i had neither experienced the problem up until then. 2. the failure occurs with the parking brake mechanism. the parking brake functions by engaging the inside brake pad on the rear brakes. there is a return spring that is suppose to disengage the brake pad when the parking brake is released. this spring is failing to disengage the inside pad causing the pad to wear abnormally. the result is that the inside pad will wear thin very quickly and eventually begin to damage the brake rotor. 3. i have returned the vehicle to the dealership for service and i was deferred to gm customer service. they informed me that they do not believe there to be a defect and will not perform the replacement work under their warranty. to solve the problem, i will be replacing all of the rear brake pads and rotors and installing a higher tension spring on the parking brake return. *tr | |||

| 2008 chevy cobalt ss under normal driving and braking conditions the rear disk brakes wear unevenly and fail prematurely. incident 1: 0% pad material on inner linings on both left and right rear wheels with >80% material outboard pads. failure occurred with about 17k miles. on inspection it was observed that gm had failed to apply lutricant to the guide pins of calipers. replacement of rotors and pads was required. incident 2: same failure as incident 1. 0% pad material on inner linings of both left and right rear wheels with >80% material on outboard pads. failure occurred within 20k miles. replacement of rotors and pads was again required. *tr | |||
