ISSUE:
On-vehicle caliper-mounted brake rotor machining equipment from Rotunda is now approved for warranty and service use. Brake roughness, pulsation and steering wheel nibble will occur when rotors wear unevenly (thickness variation). This article specifically addresses brake roughness, pulsation and steering wheel nibble resulting from disc brake rotor thickness variation induced by rotor runout.
ACTION:
Use Rotunda On-Vehicle Brake Lathes 104-00129, 104-00130, 168-00004, or 168-00005 to service vehicles with brake roughness. This method is more effective because it allows machining of the rotor while it is still mounted on the vehicle. This improves the overall run-out of the assembly.
Rotunda on-vehicle caliper-mounted brake rotor machining equipment may correct runout if used according to the equipment manufacturer's instructions. Refer to Figures 1 and 2.
Machining the rotor with the use of a caliper-mounted brake lathe will be an eligible repair under warranty for the vehicles listed.
NOTE:
THERE MAY BE ADDITIONAL MANUFACTURERS OF SIMILAR EQUIPMENT. FORD DOES NOT ENDORSE, INDICATE ANY PREFERENCE FOR, OR ASSUME ANY RESPONSIBILITY FOR EQUIPMENT FROM THESE FIRMS, OR FOR ANY SUCH ITEMS WHICH MAY BE AVAILABLE FROM OTHER SOURCES.
NOTE:
DEALERS THAT HAVE APPROVED ON-VEHICLE BRAKE ROTOR MACHINING EQUIPMENT ARE REQUIRED TO RESURFACE BRAKE ROTORS UNDER THE BUMPER TO BUMPER COVERAGE PERIOD. IF A DEALER HAS THE ON-VEHICLE BRAKE ROTOR MACHINING EQUIPMENT, ROTOR REPLACEMENT WILL ONLY BE ALLOWED WHEN THE ROTOR IS BROKEN OR DOES NOT HAVE ENOUGH MATERIAL TO ALLOW TURNING. SUCH REPLACEMENTS MUST BE AUTHORIZED BY SERVICE MANAGEMENT.
NOTE:
EXCEPTIONS TO THE LAST STATEMENT ARE REAR ROTORS ON THE TOWN CAR, GRAND MARQUIS, CROWN VICTORIA, MUSTANG AND FRONT ROTORS ON F-350, F-47 AND F-53 HEAVY DUTY LIGHT TRUCKS. ON THESE VEHICLES, ROTORS CANNOT BE MACHINED. SERVICE MANAGEMENT AUTHORIZATION IS NOT REQUIRED FOR THESE EXCEPTIONS.
