SEOCONTENT-START

Bulletin No.: PI0917F
Date: Jul-2015

This PI has been revised to remove the Regal GS and SS models, update the Parts and Warranty Information and the
procedure under Recommendation/Instructions. Please discard PI0917E.
Condition/Concern
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.
Recommendation/Instructions
Important: Do not apply the copper paste to the back of the backing plate.
Replace the front brake pads and 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.

1. Remove the front disc brake pads and discard.
2. Wipe clean both ends of the abutment area of the calipers.
3. Apply approximately 0.10 g (0.0035 oz) of copper paste to each end of the disc brake pad abutments that contact the brake caliper bracket.
   Note: Avoid a light apply of the paste as illustrated above.
4. Install the front disc brake pads.
