NOTE
Today's diesel engines have significant
torque
and startability power at low
rpm. Combinations of engine speed
and available torque may over-power
the vehicle's parking brakes.
Engaging the Parking Brake
V
ehicles with hydraulic brakes use a
manually operated driveline parking brake,
actuated by lever and cable. Pulling
upward on the parking brake lever pulls the
cable and engages the brake.
CAUTION
Unless it is an emergency, do not pull
upward
on the parking brake lever
while the vehicle is moving. Attempting
to stop with the parking brake could
cause damage to the driveline, trans-
mission, or the parking brake mecha-
nism itself.
1. Come to a complete stop.
2.
Press down completely on the
service brake pedal.
3. Pull up on the parking brake lever
until it reaches an over (top) center
position.
The parking brake indicator on the dash
will come on prior to brake being fully
applied:
4. Release the service brake pedal.
Ensure the lever is over center.
Releasing the Parking Brake
NOTE
Failure to fully release the parking
brake
before moving can cause the
brakes to overheat.
1. Press down completely on the
service brake pedal.
2.
Press the parking brake release at
lever top and lower the lever to the
floor.
The Parking Brake indicator on the
dash will turn off prior to brake
being fully disengaged.
3. Release the service brake pedal.
Parking Brake Burnishing
This procedure is recommended for new
vehicles where less lever actuation force is
required. This procedure is mandatory
whenever the driveline brake shoes or
brake drum are replaced.
