SERVICE PROCEDURE

1. Verify the incident by a test drive. Drive the vehicle as described in the IF YOU CONFIRM section in this bulletin.





2. On both front brakes, replace the one outer front brake shim (see Figure 2) on each side with the one from the PARTS INFORMATION section of this bulletin.

For more information on how to do this, see the BR section/FRONT DISC BRAKE/Removal and Installation of Brake Pad in the appropriate Electronic Service Manual (ESM).

NOTES:
^ Follow all CAUTIONS in the ESM procedure when removing and replacing brake pads.

^ Be sure to apply PBC Grease (Nissan P/N 99990-00939P) to the back of the pads and both sides of the shims. DO NOT GET ANY PBC GREASE ON THE BRAKE PAD "FRICTION" SURFACES.

3. Repeat the test drive. Drive the vehicle as described in the IF YOU CONFIRM section in this bulletin to verify the symptom is reduced.
