Brakes - Front Pad Lining Wear
Bulletin 85-5-4Date Mar.. '85
Ref. No. 85-148-5
SUBJECT: FRONT DISC BRAKE PAD LINING WEAR
MODELS AFFECTED: 1984 CENTURYS WITH JA2 OR JA3, 1985 CENTURYS WITH JA2 OR JA8 BRAKE SYSTEM AND 1985 ELECTRAS
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 1985 Electras and 1984 Centurys with JA2 or JA3 brake systems and 1985 Centurys 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 wearout condition described above.
