Your local mechanic may solve this problem with a process called refinishing, wherein the surface of the rotor is smoothed in order to remove the ridges and restore its flat surface. When this is done, a certain amount of the rotor is removed, causing it to thin. Through several times of refinishing, the brake rotors will become thinner and thinner. Since there is a minimum thickness required for a rotor to properly operate, the point will come when refinishing won’t solve the warping anymore. This will then be time when your brake rotors have already reached their limit, and refinishing will no longer be advisable because rotors will apparently lose their strength until finally broken.

The only solution for that particular rotor condition is a set of new Mercedes 300D brake rotors as replacement. This is the safest and the least expensive option in the long run, significantly saving you from possible accidents and keeping you from unnecessary expenses.
