206 DRIVING AND OPERATING
Street High Performance Brake
Burnishing Procedure
This section is for the V-Series
Blackwing with J57 carbon ceramic
brake rotors only.
This procedure should only be run on
a track or other non-public area, and
only on dry pavement.
Caution
Brake fade will occur during this
track burnish procedure and can
cause brake pedal travel and force
to increase. This could extend
stopping distance until the brakes
are fully burnished.
1. From a stop, accelerate as rapidly
as possible without activating
traction control to a speed of
100 km/h (60 mph).
2. Using the G-Force Gauge in the
HUD display, use enough pedal
force to completely stop the vehicle
in four to five seconds. (~0.7g Decel
level to stop the vehicle in a
straight line). If ABS activates,
braking is too hard.
3. Repeat the first two steps 20
consecutive times, this should take
about five minutes.
4. After completing the 20 stops, cool
the brakes by driving for 8 km
(5 mi) at 100 km/h (60 mph).
Alternative Closed Course Brake
Burnishing Procedure
This brake burnish procedure should
only be run on vehicles with a factory
equipped brake system.
This procedure should only be run on
a track and only on dry pavement.
Brake pedal fade will occur during this
track burnish procedure and can
cause brake pedal travel and force to
increase. This could extend stopping
distance until the brakes are fully
burnished.
1. Start track lapping at lower speeds
and lower braking efforts for
three minutes of driving. Allow for
increased braking distances due to
reduced brake output.
2. After Step 1, increase speed and
braking effort for the next six
minutes of lapping, gradually
ending up at 90% effort. Continue
to allow for increased braking
distance due to reduced brake
output.
3. Cool the brakes by lapping with
minimal light braking for six
minutes.
As with all high performance brake
systems, some amount of brake squeal
is normal.

setting for track use, follow this
procedure prior to the final track
alignment.
