188 Driving and Operating
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In 0 200.
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.
When this procedure is performed as
instructed, it will not damage the brakes.
The brake pads will smoke and produce an
odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
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.
