Dodge Challenger SRT 392 2015 Operating Information Manual page 197

• Prior to each track event, verify the front and
rear brake pads have more than ½ pad
thickness remaining. If the brake pads re-
quire changing, please burnish prior to track
outing at full pace.
• At the conclusion of each track event, it is
recommended that a brake bleed procedure
is performed to maintain the pedal feel and
stopping capability of your Brembo High Per-
formance brake system.
• It is recommended that each track outing
should end with a minimum of 1 cool down
lap using minimal braking.
• If equipped with a removable lower front
fascia grille, it is recommended to remove it
for track use during warm/hot weather to
improve cooling airflow to critical powertrain
and cooling system components.
• 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,
clutch – if equipped, driveline and brake
system. This may affect noise (NVH) coun-
termeasures designed into your vehicle. New
components may need to be installed to
return the system to the original NVH
performance.
• Tire pressure:
• 40psi hot, recommend 32psi front, 30psi
rear cold
NOTE:
It is recommended that you target 40psi Hot
Tire Pressure at the conclusion of each track
session. Starting at 32psi Front & 30psi Rear
Cold and adjusting based on ambient &
track conditions is recommended. Tire pres-
sure can be monitored via the Driver Infor-
mation Display (DID) 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 in-
stalled:
1. Use one track session to burnish brakes by
driving at 75% speed. Brake at approxi-
mately 0.60-0.80g max
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 1 full burnish-
ing lap after you start smelling the brakes.
Do not get them smoking heavily. This will
get them too hot and affect their life nega-
tively 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
before going back out.
