Removal Procedure

       • Do not grind brake linings.
       • Do not sand brake linings.
       • Do not clean wheel brake parts with a dry brush or with compressed air.
    Some models or aftermarket brake parts may contain asbestos fibers which can become airborne in dust. Breathing dust with asbestos fibers may cause serious bodily harm.
