Dodge Durango 2018 Supplement Manual page 31

• All SRT vehicles are track tested for 24 hours of endurance, however, it
is recommended that suspension system, brake system, prop shaft, and
½ shaft boots should be checked for wear or damage after every track
event.
• Track usage results in increased operating temperatures of the engine,
transmission, driveline and brake system. This may affect Noise Vibra-
tion Harshness (NVH) countermeasures designed into your vehicle. New
components may need to be installed to return the system to the original
NVH performance.
• Tire pressure:
– Below 42 psi (289 kpa) hot and 33 psi (227 kpa) cold recom-
mended.
NOTE: It is recommended that you target below 42 psi (289 kpa) Hot Tire
Pressure at the conclusion of each track session. Starting at 33 psi (227
kpa) Cold and adjusting based on ambient & track conditions is recom-
mended. Tire pressure can be monitored via the instrument cluster display
and can assist with adjustments.
Track burnishing your brakes:
To avoid "green lining fade" during track use, the brake pads and rotors
must have a thermal burnish for factory installed components or when new
brake friction components are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake
at approximately 0.60 - 0.80g max without ABS intervention.

2. Lap the track in this manner until you start smelling the brakes.
Continue for another ½ lap at speed, then do a two lap cool down with
minimal brake applies. Make sure the brakes are not smoking. If they
are, do another cool down lap.
3. Do not continue for more than one full burnishing lap after you start
smelling the brakes. Do not get them smoking heavily. This will get them
too hot and affect their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least 30 min. If an
infrared thermal gun is available, allow rotors to cool to 200 °F (93.3 °C)
before going back out.
5. There should be a thin, ash layer when inspecting the pads installed in
the caliper. Having the ash layer go more than half the thickness of the
pad material indicates too aggressive of a burnish.
6. Sometimes, a second burnish session is required. If the pads start
smelling in the next track session, reduce speed and braking decel to
burnish targets and follow steps 2-4.
7. New pads installed on old rotors still need to be burnished. New rotors
installed with old pads should be burnished at the track or street driven
for 300 city miles to develop an adequate lining transfer layer on the
rotor surface prior to track use.
8. Rotors that pulsate during track use should be replaced.
