BRAKE ROTOR CARE DURING NEW VEHICLE STORAGE
This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Please discard previous versions of this bulletin.

APPLIED VEHICLES: New, unsold Nissan Dealer in-stock units equipped with wheel
protector covers
SERVICE INFORMATION
For vehicles delivered to the dealers with wheel protector covers:
 Do not remove the wheel protector covers during Pre-Delivery Inspection (PDI)
unless the vehicle is being delivered to a customer.
NOTE: Cut small “X” holes in the wheel protector covers to access the transmitters
(valve stems). For storage purposes, adjust tire pressures to 5 psi above the Cold
Tire Pressure specification listed on the Tire and Loading Information label.


Leave the wheel protector covers on the road wheels for the duration of the storage
period, up to six (6) months.
NOTE: The wheel protector covers should be removed no later than six (6) months
after their installation date.




Move the vehicle so that the tires rotate 90°, in one direction only, every 30 days of
storage.
Remove the wheel protector covers and install any wheel trim as applicable at the
time of customer delivery.
 Wheel protector covers help prevent cosmetic rotor corrosion.

Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

COSMETIC ROTOR CORROSION REMOVAL PROCEDURE
NOTE: It is the dealer’s responsibility to perform the cosmetic corrosion removal procedure.
It is not covered under warranty.
Examples of cosmetic rotor corrosion:

Figure 2
If, at the time of sale, there is cosmetic rotor corrosion when the protector covers are
removed:
1. Burnish the brakes by driving the vehicle on a straight, smooth road at about 30 MPH
(50 kph).
2. Use medium brake pedal effort to bring the vehicle to a complete stop from about 30
MPH (50 kph). Adjust pedal pressure so that the vehicle stopping time is 3-5 seconds.

3. Cool the brake system by driving at about 30 MPH for approximately 1 minute without
stopping.
4. Repeat steps 1-3 ten times to complete the burnishing process.


If the rotors do not have pad marks after the driving and braking procedure is
complete, do not machine the rotors.

Figure 3


If any rotor has a pad mark after driving and braking, machine the rotors using an
on-car lathe:
 If there is a pad mark on the front rotor(s), machine both front rotors.
 If there is a pad mark on the rear rotor(s), machine both rear rotors.
NOTE: Machine rotors using an “on-car” brake lathe. Make a light cut with the lathe
set to slow advance.
NOTE: It is the dealer’s responsibility to perform the cosmetic corrosion removal
procedure. It is not covered under warranty.

When reinstalling the wheels, make sure to use a torque wrench when tightening
