Effective approximately May 1, 1986 DeVilles and Fleetwoods will be assembled with front disc brake pads which have a new lining material (DM 8087) and a new three layer noise insulator. These brake pads can be identified as shown in the illustration.
The new front disc pads are available from GMWDD under part number 12321422. Front disc brake noise can be reduced on 1985-1986 DeVilles and Fleetwoods manufactured prior to the above brake pad change by the installation of the new lining service kit.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
