I have a 05 with 14,950 for a while i notice after driving for a while my front rotors are warped. But this happens mostly on the hwy. I dont want to go through the hassle of getting them redone but i should. []

 

have you changed them before or are they the ones that came with the car

 

It's called a warrenty. Take it to the dealership and let them take care of it for free.

 

I had the same problem with my '05. Just take it to the dealer they will take care of it for you. But if you are wondering just for your info I did have the same problem, brake pulsation only at higher speeds. If there is one beef I have with the cobalt it is with their brakes.

 

R1 concept rotors with Bendix pads, they will last you what seems like forever.
