Condition
Some customers may comment on a squeal or squeak noise from the front brakes. This condition normally only occurs on initial brake applications after the vehicle has sat for an extended time. The condition occurs typically under light braking, in speeds under 16 km/h (10 mph). After 1-6 brake applies, or after braking at higher speeds, the noise no longer occurs. This condition may occur more often in high humidity conditions.
Correction
Apply a coat of copper paste to completely cover the pad backing plate abutments on each end.

Condition
Some customers may comment on a squeal or squeak noise from the front brakes. This
condition normally only occurs on initial brake applications after the vehicle has sat for an
extended time. The condition occurs typically under light braking, in speeds under 16 km/
h (10 mph). After 1-6 brake applies, or after braking at higher speeds, the noise no longer
occurs. This condition may occur more often in high humidity conditions.
Correction Apply a coat of copper paste to completely cover the pad backing plate abutments on
each end.
Service Procedure
Important: The use of wheel cleaners or power
washers directly pointed at the brake caliper may wash
the copper paste off of the brake pads. It may be
necessary to apply the copper paste again if the
lubricant is washed away. The copper paste should be
applied whenever the brake pads are removed or
replaced.
Apply a coat of copper paste to completely cover the
pad backing plate abutments on each end. The paste
should not extend onto the friction material. Follow the
instructions listed below.

GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these
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 your GM dealer for information on whether your vehicle may benefit from the
information.
