You are correct - Warped is a better term than 'out of round'. I could not think of the word 'warped'.
I believe that undersizing the brake components is relatively new - 10-12 years or so - saves weight, supposedly, for a slight increase in fuel mileage. However, new rotors will cost much more than what I may have saved in fuel expense. The old slight of hand trick. GM should not skimp on brakes when engineering a car that weighs 4400 pounds.
I am not happy. I will go to see a reputable private repair shop today. I will see what he says. I do not feel any throbbing in the brake pedal if I apply the brakes at 60-65. If there is any warping, it seems that it could be ignored as far as replacing the rotors. I believe that this shop will turn rotors. (not all shops have these machines). I dont tow a trailer, thus machining the rotors one time should be acceptable.
I appreciate your reply.
