I am going to purchase a new set of front rotors and brake pads. I will also torque the wheels myself with a torque wrench according to my owners manual. I appreciate all of the replies. The one thing I am curious about is why only the left rotor has warped and not the right? I'm just worried about going through the expense of new parts and possibly ruining them. Since owning my M.B. and with the help of this site and it's members, I'm am becoming familiar with the DOs and DONTs of M.B. car care. Thanks for you help. I would still like to know why only the left rotor has warped? andy
