SUBJECT:
BRAKE LINING PULLAHEAD
MODELS AFFECTED:
1989 and 1990 ELECTRA/PARK AVENUES AND LESABRES EQUIPPED WITH JM4 AND JL9 BRAKE SYSTEMS
The 1990 Electra/Park Avenues and LeSabres front lining material, edge code DM 342EE, has been pulled ahead on the 1989 Electra/Park Avenues and
LeSabres with ABS Brake Systems only. The purpose of the pullahead is to reduce the potential for brake squeal on 1989 vehicles with ABS brake
systems.
It is recommended that the 1990 lining, edge code DM 342 EE, not be used to service 1989 and prior year Electra/Park Avenues and LeSabres without
ABS Brake Systems; i.e., vehicles with base brake systems. The 1990 lining, DM 342 EE, has a lower coefficient of friction than the current o.e. and
service lining Edge Code DM 127 EE, and should only be used to service 1989 vehicles with ABS and 1990 Electra/Park Avenues with both base and
ABS brake systems.
Vehicles produced at the following assembly plants PRIOR to VIN numbers equipped with both JM4 and JL9 should use lining 12321422.
