156 Driving and Operating
Rear Axle Fluid
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
with new fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants 0 269.
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
Regularly inspect the drive shaft/
prop. shaft couplings and half shaft
boots for cracking or grease
leakage. It is not recommended that
the vehicle be used for ongoing race
track/competitive driving.
For extended track use, GM
recommends installing a rear
differential cooler to protect the
rear axle.
Brake Fluid
For track events or competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a
dry boiling point greater than 279 °C
(534 °F). After conversion to the
high performance brake fluid, follow
the brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT-5 brake fluids.
Brake Burnishing
To prepare the Camaro brake
systems for track events and racing,
complete the appropriate high
performance brake burnishing
procedure described below.
New brake pads must be burnished
before racing or competitive driving.
Caution
These procedures are specific to
the Camaro SS, or LT with Y4Q
Heavy Duty Cooling System that
is equipped with J55 brakes. This
procedure should not be run on
other Camaro models as damage
may result.
Caution
The new vehicle running-in period
should be completed before
performing the brake burnishing
procedure or damage may occur
to the powertrain/engine. See
New Vehicle Run-In 0 164.
When performed as instructed, this
procedure will not damage the
brakes. During the burnishing
procedure, the brake pads will
smoke and produce an odour. The
braking force and pedal travel may
