BRAKE SQUEAL POSSIBLE CAUSES

Model and Year 1984 CORVETTE

Brake squeal has been experienced on some 1984 Corvettes. Two (2) possible causes for brake squeal are:

1. Some very early Corvettes may exhibit front brake squeal that may be caused by "corrosion insulators", located on outboard pads, becoming dislodged and rubbing against the center portion of the rotor. A new insulator to brake pad adhesive was implemented shortly after start of production. Vehicles experiencing this condition can be repaired by installing front brake pads, P/N 14067582.

2. Rear brakes may have a sensitivity to "tip-in" brake squeal on light to moderate brake stops. "Tip-in" brake squeal vehicles can be repaired by installing rear rotors, P/N 14084143. It is suggested that both rear rotors be replaced on tip-in squeal condition vehicles. Vehicles starting with serial number E5136435 were built with P/N 14084143 rear rotors.

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.
