154 Driving and Operating
4. Apply the brakes 25 times from
100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.
As with all high performance brake
systems, some amount of brake
squeal is normal.
Alternative Closed Course Brake
Burnishing Procedure
This brake burnish procedure
should only be run on vehicles with
the J55 Z51 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.
Brake Cooling Kit
Prior to any track event, high speed
driving event, or competitive driving,
the following should be completed:
.
Ensure all brake cooling parts
are correctly and securely
installed.
.
Install the rear lower control arm
cooling ducts per the instructions
included with the kit. After any
track event or competitive
driving, remove the rear lower
control arm cooling ducts. These
parts are for track use only.
.
Inspect for and remove any
blockage in the ducts.
.
Inspect and replace any duct
that has damage.
