BRAKE ROTOR CARE DURING NEW VEHICLE STORAGE
APPLIED VEHICLES: New unsold Nissan Dealer in-stock units equipped with wheel
protector covers
This bulletin has been amended to include the newest models and model years, and amend the
tire pressure specification for storage. Please discard previous versions of this bulletin.

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 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.

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. Drive and brake the vehicle 10 times from 30 MPH to 0 MPH.

2. After driving and braking, inspect the rotors for brake pad marks.


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



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.
