terryallan- how do you have them turned? Would it be cheaper to just buy new?
No it is not cheaper to buy new. Turning rotors is VERY inexpensive. You simply take off the rotors, and take them to a mechanic. He puts them on a lathe, and skims off the high spots. Turning them "true"
Some garages can turn them while still on the vehicle. Now IF the rotors are warped badly enough, or very worn, They can turn a hole in them. Then you would have to replace them
Many things can cause the rotors to warp. The main culprit is cold water. Cold water on a hot rotor is almost a guaranteed warped rotor. That is why when I hit a puddle, and see the steam come off the brakes, I gently apply the brakes just enough to dry them.
