6 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
BRAKE SYSTEM MAINTENANCE
WARNING!
Perform this procedure in a controlled environment,
as high speeds and high rates of deceleration are
necessary in order to complete this procedure. Fail-
ure to follow this warning can result in an accident
with serious or fatal injuries.
WARNING!
In a collision, you and your passengers can suffer
much greater injuries if you are not properly buck-
led up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.
All new brake systems have a burnishing (break-in)
period. This burnishing (break-in) period will vary ac-
cording to individual driving habits and driving condi-
tions (e.g. rush hour, city, highway, etc). Smoke and odor
associated with brake burnishing is normal. Therefore,
we recommend using the following procedure should
you want to accelerate the burnishing (break-in) period
on the heavy-duty brake system on your vehicle:
In a controlled environment, perform a series of high-
speed threshold braking stops by accelerating the vehicle
to a speed of 60 to 70 mph followed each time by a high
deceleration stop. Repeat this 15 to 20 times, in sequence,
with a 15 to 20 second period of rest in between each
stop. After completing this procedure, allow the brakes to
cool completely before driving the vehicle again.
