Recall - Front Brake Caliper Tightening Torque
File In Section: Product Recalls
Bulletin No.: 04049
Date: June, 2004
PRODUCT SAFETY RECALL
SUBJECT:
FRONT BRAKE CALIPER BOLT TORQUE
MODELS:
2004 CHEVROLET IMPALA, MONTE CARLO
2004 PONTIAC GRAND PRIX
CONDITION
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2004 model year Chevrolet Impala and Monte Carlo,
and Pontiac Grand Prix vehicles. Some of these vehicles may have left and right front wheel assemblies in which the two bolts that attach the front brake
caliper to the steering knuckle were not tightened adequately. If too much movement occurs between the caliper bracket and knuckle, the bolt(s) may
back out or fracture. Depending on whether one or both bolts back out or fracture, the result can be 1) locking of the affected wheel during braking and
an abrupt steering input in the direction of the locked wheel, 2) reduced braking and noise from the affected wheel, or 3) severing of a brake hose,
increased brake pedal travel, and reduced steering control. If this were to occur, it could result in a vehicle crash without prior warning.
CORRECTION
Dealers are to tighten both bolts to the specified torque.
VEHICLES INVOLVED
Involved are certain 2004 model year Chevrolet Impala and Monte Carlo, and Pontiac Grand Prix vehicles built within the VIN breakpoints shown.
