parking brake FORD F750 2002 10.G Owners Manual

Trailer ABS brake system (if equipped)
Illuminates briefly when the engine
is powered-up and only when a PLC
trailer or a PLC diagnostic tool is
connected. If the light remains on
after the vehicle is started,
continues to flash or fails to illuminate, have the system serviced
immediately.
Parking brake warning (Hydraulic brakes only)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to theSeating
and safety restraintschapter.
Check trans (Allison automatic transmission)
The lamp will illuminate for several
seconds after the ignition is turned
to the ON position. Illumination of
this light indicates that a problem
has been detected and shifting may
be restricted. Depending upon the
severity of the problem, the
read-out digit on the shifter display
may be blank. Operation may
continue in order to reach service assistance. The ECU may not respond
to shift selector requests, since operating limitations are being placed on
the transmission, i.e. upshifts and downshifts may be restricted.
Direction changes will not occur.
Refer to the Transmission Operator's Manual for more information.

One time disable
Any time the safety belt is buckled and then unbuckled during an
ignition ON cycle, BeltMinder will be disabled for that ignition cycle only.
Deactivating/activating the BeltMinder feature
Read steps1-9thoroughly before proceeding with the
deactivation/activation programming procedure.
The BeltMinder feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that:
²The parking brake is set.
²The gearshift is in P (Park) (automatic transmission) or the neutral
position (manual transmission).
²The ignition switch is in the OFF position.
²All vehicle doors are closed.
²The driver's safety belt is unbuckled.
²The parklamps/headlamps are in OFF position (If vehicle is equipped
with Autolamps, this will not affect the procedure).
To reduce the risk of injury, do not deactivate/activate the Belt
Minder feature while driving the vehicle.
1. Turn the ignition switch to the RUN (or ON) position. (DO NOT
START THE ENGINE.)
2. Wait until the safety belt warning light turns off. (Approximately 1±2
minutes.)
²Steps 3±5 must be completed within 60 seconds or the procedure will
have to be repeated.
3. Buckle then unbuckle the safety belt three times, ending with the
safety belt unbuckled. This can be done before or during BeltMinder
warning activation.
4. Turn on the parklamps/headlamps, turn off the parklamps/headlamps.

STARTING PROCEDURES
Operating precautions
²Always shift to a lower gear at high altitudes to prevent engine
smoking.
²Avoid extended and unnecessary idling.
Diesel engine vapors are combustible. Do not operate the engine
in an enclosed area. These vapors can be sucked through the air
intake system and cause engine acceleration and overspeeding, which
may result in bodily injury and extensive property damage. The
equipment owner and operator are responsible for safe operation in a
hostile environment.
Starting the engine
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2400 transmissions).
If your vehicle is equipped with an
air intake heater, the heater will
activate in cooler weather. If the
Wait to startlight illuminates,do
notcrank the engine until the light
goes off.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could cause an explosion
and result in vehicle damage, property damage and/or personal injury.
2. Do not depress the accelerator during starting the engine.
3. Start the engine.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.

With the ABS light on, the anti-lock brake system is disabled and normal
braking is still effective unless the brake warning light also remains
illuminated. (If your parking brake warning lamp illuminates, have your
vehicle serviced immediately).
Using ABS
²In an emergency or when maximum efficiency from the ABS is
required, apply continuous full force on the brake. The ABS will be
activated immediately, thus allowing you to retain full steering control
of your vehicle and, providing there is sufficient space, will enable you
to avoid obstacles and bring the vehicle to a controlled stop.
²The Anti-Lock system does not decrease the time necessary to apply
the brakes or always reduce stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
²We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, pull handle up until it
snaps into the locked position.
A properly adjusted parking brake
requires approximately 116 Nm (90
lb-ft) to activate. For maximum
parking brake effectiveness turn
handle clockwise to adjust for wear.
When the parking brake is out of
adjustment, seek service
immediately.

The parking BRAKE warning lamp
in the instrument cluster illuminates
and remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
Do not use the gearshift selector in place of the parking brake.
Always set the parking brake fully AND make sure the gearshift
selector is in R (Reverse) for vehicles equipped with manual
transmission, P (Park)(if equipped)or N (Neutral) for vehicles with
automatic transmission. Use of wheel chocks is also recommended in
hilly or off-road usage.
Unexpected and possible sudden vehicle movement may occur if
these precautions are not taken.
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake only applies
retardation to the rear wheels, the vehicle's stopping distance will
increase greatly and the handling of your vehicle will be adversely
affected.

Pull the parking brake knob out to
apply the parking brake. Push the
knob in to release the parking
brake.
Parking brake warning chime Ð F650 SuperCrewzer
If a chime sounds when pulling the knob out, your parking brake is not
functioning properly, seek service immediately. This chime will sound
until the yellow knob is pushed in or eight minutes have passed. If the
yellow knob is pulled out again, the chime sounds as a reminder that
immediate service is required to the parking brake system.

Releasing spring brake manually Ð F650 SuperCrewzer
Do not attempt to disassemble the parking brake chamber under
any circumstances. The high spring load may cause serious
injury if the chamber clamps are removed.
If air pressure is released from the spring brake chamber the power
spring applies the brake and, unless air pressure can be re-established,
the spring brake must be released as follows in order to move the
vehicle.
Block the wheels to prevent the vehicle from moving.
Unexpected and possibly sudden vehicle movement may occur if
these precautions are not taken.
Remove the clevis which is attached
to the end of the spring chamber
rod. This can be done by using a
wrench on the flats of the rod to
thread it out of the clevis. There is
sufficient thread length in the clevis
to fully release the parking brake.
Burnish procedure Ð All except F650 SuperCrewzer
For optimal performance of a new parking brake system/new linings
perform the following procedure:
1. While driving the vehicle at 40 km/h (20 mph) apply the parking brake
(with applicable force to set to approximately 18kg [40 lbs.]). Allow the
vehicle to come to a complete stop.
2. Release the parking brake, drive 16.8 km (1.5 miles) to cool the
brakes.
3. Repeat steps 1 through 2 ten times.

brakesin this chapter.
Parking brake
Do not use the gearshift selector in place of the parking brake.
Always set the parking brake fully AND make sure the gearshift
selector is in R (Reverse) for vehicles equipped with manual
transmission or N (Neutral) for vehicles with automatic transmission.
Unexpected and possible sudden vehicle movement may occur if
these precautions are not taken.
If the service brakes should fail to operate while the vehicle is in motion,
you can make an emergency stop with the parking brake. The stopping
distance, however, will be much greater than normal. Repairs should be
made immediately to an inoperative air brake system circuit.
Parking brake control
Pull the yellow parking brake knob
out to apply the parking brake. Push
the knob in to release the parking
brake.
This control is used for
parking only. Do not leave
the vehicle unattended after
setting the parking brake without
placing the transmission in R
(Reverse) for manual transmission
or N (Neutral) for automatic
transmission. Use of wheel chocks
is also recommended in hilly or
off-road usage.
Releasing spring brake with air pressure
The air system in all vehicles with spring-actuated rear wheel parking
brakes is equipped with a tank valve located on the supply or service air

tank for connection to an outside air supply. The valve permits the
system to be recharged with air from an outside source, releasing the
spring-actuated parking brakes. The vehicle may then be towed in an
emergency.
An outside air source can be used only if the protected system is in
operating condition. If air pressure cannot be restored in the protected
air system, the spring-actuated brakes must be released manually.
Releasing spring brake manually
Do not attempt to disassemble the parking brake chamber under
any circumstances. The high spring load may cause serious
injury if the chamber clamps are removed.
If air pressure is released from the spring brake chamber the power
spring applies the brake and, unless air pressure can be re-established,
the spring brake must be released as follows in order to move the
vehicle.
Block the wheels to prevent the vehicle from moving.
Unexpected and possibly sudden vehicle movement may occur if
these precautions are not taken.
Impact wrenches should not be used as they may damage the piston and
prevent proper caging of the spring. Do not apply more than 68 Nm (50
lb-ft) torque to the release bolt nut.
1. Remove the stud tool and nut
from the carrying pocket on the
brake chamber assembly.
2. Remove the access plug from the
end of the spring chamber.
3. Insert the release stud through
the opening in the chamber and into
the spring pressure plate.
