FRONT DISC BRAKE PADS LINING WEAR-NEW PADS P/N'S

1984 6000 WITH JA2 OR JA3 & 1985 6000 WITH JA2 OR JA8 BRAKE SYSTEM

Some subject vehicles produced approximately June 20, 1984 through September 15, 1984 may experience front lining wear on only one pad out of the four on the vehicle. Wear of one pad in less than 10,000 miles may be experienced. If this condition is experienced, use the front pads in kit part number 12321410 which is available from GMWDD. This kit is available for all 1984 6000's with JA2 or JA3 brake systems and 1985 6000's with JA2 and JA8 brake systems. If the front pads are replaced due to the early wear condition, the rotors should be inspected for roughness and resurfaced if required or replaced if wear exceeds serviceability guidelines.

NOTICE: The inboard pads use a thermal layer approximately .100" thick. When both the inboard and outboard pads are worn due to normal wear, the inboard pad will appear to have less wear due to the layer. This is a normal appearance and should not be confused with the wear condition described above.

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.
