INSPECTION



With the drum off the vehicle, inspect it for any cracks, scores, grooves, or an out-of-round condition. If the drum is cracked, replace it. Light scoring can be removed with emery cloth or fine sandpaper. If the scoring is extensive, have the drum turned. Never have a drum turned more than 0.060 in. (1.524mm)
