Condition Some customers may comment about a squeal/squeak noise during light brake apply.
Cause
Some driving conditions or climates can cause a brake squeal when the brakes are first
applied or lightly applied.
The SS model is equipped with Brembo Performance Brakes (RPO J6G). Brake squeak/
squeal noise is a common characteristic on vehicles equipped with performance brakes.
The brakes are designed for more aggressive braking to produce shorter braking
distances. Repetitive light brake apply will induce a brake squeal/squeak condition over
time. GM Engineering recognizes there are certain driving conditions that require a light
brake apply such as stop and go traffic, drive-thru’s, etc. and has investigated the
frequency (MHz) at which the brake noise is produced.
Correction
Note: This correction only applies to vehicles with brake squeal/squeak noise during
light brake apply. This DOES NOTapply to concerns related to worn brake pads, glazed
brake pads or brake pulsation.
Note: GM Engineering has determined a higher carbon contented rotor can effectively
reduce brake squeak/squeal noise during light brake apply.
Replace the front brake rotors.
Important: Brake squeal/squeak noise does not cause brake pad wear. Brake pad wear
is a maintenance item. If brake pads are replaced, it should be done so as customer pay
or customer enthusiasm which requires Service Manager approval.
Note: This bulletin provides vehicle or part information ONLY and is not a statement of
warranty or an extension of warranty.

Service Procedure
Refer to Front Brake Rotor Replacement (J6G) in SI.
Burnishing the brake pads and brake rotors is
necessary in order to ensure that the braking surfaces
are properly prepared after service has been performed
on the disc brake system.
This procedure should be performed whenever the disc
brake rotors have been refinished or replaced, and/or
whenever the disc brake pads have been replaced.
1. Select a smooth road with little or no traffic.
2. Accelerate the vehicle to 48 km/h (30 mph).
Note: Use care to avoid overheating the brakes while
performing this step.
3. Using moderate to firm pressure, apply the brakes
to bring the vehicle to a stop. DO NOTallow the
brakes to lock.
4. Repeat steps 2 and 3 until approximately 20 stops
have been completed. Allow sufficient cooling
periods between stops in order to properly burnish
the brake pads and rotors.
