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.
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 break-in period
should be completed before
performing the brake burnishing(Continued)
Caution (Continued)
procedure or damage may occur
to the powertrain/engine. See
New Vehicle Break-In0174.
When performed as instructed, this
procedure will not damage the
brakes. During the burnishing
procedure, the brake pads will
smoke and produce an odor. The
braking force and pedal travel may
increase. After the procedure is
complete, the brake pads may
appear white at the rotor contact.
Run this procedure in a safe
manner and in compliance with all
local and state ordinances/laws
regarding motor vehicle operation.
Run this procedure only on dry
pavement.

Racing/Track Brake Burnishing
Procedure
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. Apply the brakes 25 times starting at 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 applying the brakes.
This first step may be skipped
if there are more than 320 km
(200 mi) on the brake pads.
2. Repeatedly apply the brakes from 100 km/h (60 mph) to
25 km/h (15 mph) while
decelerating at 0.8 g. This is a
hard brake application, without
activating the Antilock Brake
System (ABS). Drive for at least 1 km (0.6 mi) between
stops. Repeat until the brake
pedal travel starts to increase.
Depending on conditions, this
should take no longer than 25
brake applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
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.
Front Tire Deflectors, Lower
Control Arm Deflectors, and
Disc Splash Shields (SS Only)
Before any racing event, remove the
tire deflectors in the front of the
vehicle, and replace the original
deflector and splash shield with the
tall deflector and small splash
shield.
Caution
Race track driving with the
original front disc brake splash
shield and front tire deflector may
result in brake pedal fade due to
high rotor temperatures.
To install the tall deflector and small
splash shield:
1. Remove the tire deflector.
2. Remove the front wheels.

3. Remove the calipers (3) fromthe knuckle.
4. Remove the brake rotors (2).
5. Remove the original front splash shields (1).
6. Remove the lower control arm deflectors.
7. Detach the wheel speed sensor harness clips from the
lower control arm deflector.8. Install the small splash shieldswith two screws (2) per corner.
Torque to 9 Y(80 lb inch).
Caution
Failure to reattach the wheel
speed sensor harness clips
correctly could cause interference
with the wheel speed sensor, and
could damage the vehicle.
9. Re-attach the wheel speed sensor harness clips by
pushing them from the bottom up, on the back tab. On the
original deflector, the push pins
are pushed from the top down.
10. Install the tall deflectors with three screws (1) per corner.
Torque to 3.3 Y(29 lb inch).
When installing new control
arms, torque the three screws
to 4.5 Y(40 lb inch).
11. Install the front rotors with one screw per corner. Torque to
9Y (80 lb inch).
12. Apply liquid thread adhesive to
the caliper bolts (GM Part No.

Goodwrench 12345493). Install
the calipers with two screws (1)
per corner. Torque the caliper
bolts to 200Y(148 lb ft).
13. Reinstall the front wheels using the wheel nut torque. See
Capacities and Specifications
0320.
Caution
After a track event, remove the
tall deflector and the small splash
shield and reinstall the original
deflector and splash shield.
(Continued)
Caution (Continued)
Failure to reinstall the original
parts may lead to corrosion, loss
of output, noise, premature brake
pad and rotor wear, reduced
high-speed wet braking, and
damage to the tall deflector.
14. After a track event, repeat the steps to reinstall the original
lower control arm deflectors
and splash shields.
15. Reinstall the tire deflectors.

Vehicle Care 299
Caution
To avoid surface damage on
wheels and wheel trim, do not
use strong soaps, chemicals,
abrasive polishes, cleaners,
or brushes. Use only GM
approved cleaners. Do not drive
the vehicle through an automatic
car wash that uses silicon carbide
tire/wheel cleaning brushes.
Damage could occur and the
repairs would not be covered by
the vehicle warranty.
Brake System
Visually inspect brake lines and
hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect all other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged, loose,
or missing parts or signs of wear at
least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and
steel fuel door hinge unless the
components are plastic. Applying
silicone grease on weatherstrips
with a clean cloth will make them
last longer, seal better, and not stick
or squeak.
Underbody Maintenance
At least twice a year, spring and fall,
use plain water to flush any
corrosive materials from theunderbody. Take care to thoroughly
clean any areas where mud and
other debris can collect.
Do not directly power wash the rear
axle output seals. High pressure
water can overcome the seals and
contaminate the rear axle fluid.
Contaminated fluid will decrease the
life of the axle and should be
replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
