2007 FORD F650 parking brake

Note:Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a buildup of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
The following cold weather idling guidelines must be followed:
•Avoid idling the engine for more than 10 minutes at a time.
•Use a minimum of 45 Cetane Diesel fuel or use Cetane Index
improvers from a reputable manufacturer.
•Maintain a minimum idle of 1250 RPM by using the hand throttle.
Always make sure that the parking brake is applied and the
transmission is in neutral before applying the hand throttle.
•Maintain the engine cooling system properly.
•Do not shut the engine down after an extensive idling period (10
minutes or more). Drive the vehicle under load for several miles at
normal operating temperatures to burn off any accumulated carbon
and varnish.
•Consider using an engine block heater, approved winter fronts and/or
radiator shutters where conditions warrant.
Winter fronts
The use of winter fronts, or other air-restrictive devices mounted in front
of the radiator on vehicles with chassis-mounted charge air coolers, are
not recommended unless extremely cold weather conditions exist. Air
flow restriction can cause high exhaust temperatures, power loss,
excessive fan usage and a reduction in fuel economy. If you must use a
winter front, the device should have a permanent opening of at least 120
sq in. (774 sq. cm) directly in line with the fan hub.
Hot weather operation
•Keep the engine cooling system filled with a clean, permanent coolant
solution to protect against damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
Above normal coolant temperatures could be experienced while driving
in a transmission gear ratio which lugs the engine. To correct this
problem, engine speed should be increased by downshifting in to the
next lower gear to increase engine RPM.

Backing up
To reduce the risk of the possibility of personal injury while
backing the vehicle, always be sure your vehicle’s path is clear.
Before backing your vehicle, be sure you can do so safely. If anything
behind the cab limits your view, do not rely on mirrors alone to ensure
that your intended path is clear. If other people are in the vicinity, have
someone standing well behind your vehicle and outside of your intended
path (visible through an exterior mirror) guide you as you back up.
Although OSHA or some governmental regulations may require the use
of an electrical or mechanical back-up alarm to warn bystanders, such an
alarm does not ensure that the intended path is clear. When in doubt,
get out of the vehicle and visually check the intended path is clear;
back-up slowly as to allow others time to move, if necessary.
If an electrical back-up alarm is installed, it should be connected to the
back-up lamp circuit.
Parking your vehicle
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires will act against the curb to stop the vehicle. The front
wheels will be more effective at stopping a rolling vehicle than the rear
wheels.
When parking your vehicle, do not leave the transmission in
gear; if the key is in the ON position and the vehicle rolls, the
engine could start. Failure to follow these instructions could result in
an unattended vehicle moving, possibly causing personal injury or
property damage.
Driving through water
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine, drive axles or the transmission
(through the breather ports).
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.

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.
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.
When the parking brake is out of adjustment, seek service immediately.
The parking BRAKE warning lamp
in the instrument cluster illuminates
and will remain illuminated (when
the ignition is turned on) until the
parking brake is released.

Push the palm release lever on the
parking brake handle and push
down as far as possible to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
If the parking brake is fully
released but the parking
brake warning lamp remains
illuminated, the brakes may not be
working properly. See your dealer
or a qualified service technician.
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.
POWER PARK (AIR-OPERATED PARKING BRAKE) OPTION (IF
EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, air-released driveline parking brake. It is controlled by a
yellow, dash-mounted parking brake knob.
Applying the parking brake
To apply the parking brake, pull the yellow, dash-mounted parking brake
knob. A red light on the dash panel should illuminate indicating that the
parking brake has been successfully set.
Note:If the park brake indicator light blinks and a warning chime
sounds when the control knob is pulled, the parking brake is not
functioning properly; seek immediate service from your dealer. Refer to
theParking Brake Warning Systemsection.

Releasing the parking brake
Note:Read and understand the following steps and perform them
whenever you prepare to drive the vehicle.
Note:The parking brake will not disengage unless sufficient system air
pressure is available.
For vehicles with automatic transmissions - dash-mounted push
button (Allison 3000 Series) and steering column-mounted (Allison
2200 and 2500) gear selection:
1. With the engine running, depress and hold the service brake pedal.
2. Wait until system air pressure is above 100 psi (690 kPa).
3. Select the appropriate drive gear.
4. Push the yellow, dash-mounted parking brake knob.
For vehicles with manual transmissions - (TTC 7–speed,
Eaton/Fuller 5–speed and 6–speed):
1. With the engine running, depress and hold the service brake pedal.
2. Wait until system air pressure is above 100 psi (690 kPa).
3. Depress and hold the clutch pedal.
4. Select the appropriate drive gear.
5. Push the yellow, dash-mounted parking brake knob.
Hold the brake pedal down while moving the gearshift lever from
position to position. If the brake pedal is not held down, the
vehicle may move unexpectedly resulting in property damage, personal
injury or death.
Parking brake light illumination due to low air pressure
If at any time during vehicle operation air pressure is too low, the
parking brake may apply and the parking brake light will turn on.
If the parking brake is applied due to low air pressure, immediate service
is required to the parking brake system.
Parking brake warning system
If the park brake light blinks and a chime sounds when pulling the yellow
control knob out, this indicates the parking brake is not functioning
properly; seek service for the parking brake immediately.
The light will blink and the chime will sound until the yellow control
knob is pushed in or approximately eight minutes have passed. If the

yellow control knob is pulled out again, the light will blink and the chime
will sound as a reminder that immediate service is required to the
parking brake system.
Releasing spring manually
Do not attempt to disassemble the parking brake chamber under
any circumstances. The high spring load may cause serious
injury.
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 help prevent the vehicle from moving.
Unexpected and possibly sudden vehicle movement may occur if
these precautions are not taken.
Loosen the jam nut (1) and un-thread the adjustment rod (2) from the
chamber to reduce tension on the cable (3). Continue to un-thread the
adjustment rod all the way and remove it from the chamber. The nut and
shaft are metric.

Do not continue to operate the vehicle with a failure of one of
the systems. Take the vehicle to your dealer for service
immediately.
Air brake reservoir draining
Failure to drain air brake reservoirs can result in a reduction or
loss of braking ability due to fluid accumulation in the reservoir
and/or possible freeze-up during cold weather.
Drain all the air brake reservoirs
daily, completely to 0 psi/kPa, by
opening the draincock at the ends
of the tanks (where accessible.
Pull-chains are used when the
drains are undercab or otherwise
inaccessible). Close draincock after
complete draining. Air tanks
equipped with automatic moisture
ejector valves may also be drained
manually as required to maintain a
dry air system. Contact your dealer if you are unsure of the air reservoir
locations or the draining procedure.
Parking brake
Do not use the gearshift selector in place of the parking brake;
unexpected and possible sudden vehicle movement may occur if
these precautions are not taken. Always set the parking brake fully
AND make sure the gearshift selector is in R (Reverse) for vehicles
equipped with manual transmission, N (Neutral) for vehicles with
automatic transmission (except Allison 2200 transmission) or P (Park)
(Allison 2200 transmission).
If the service brakes should fail to operate while the vehicle is in motion,
you can make an emergency stop with the parking brake. Since the
parking brake only applies stopping power to the rear wheels, the
vehicle’s stopping distance will greatly increase and the handling of the
vehicle will be adversely affected. Repairs should be made immediately
to an inoperative air brake system circuit.

Parking brake control (knob)
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, N (Neutral) for
automatic transmission (except
Allison 2200 transmission) or P
(Park) (Allison 2200
transmission). Use of wheel
chocks is also recommended in
hilly or off-road usage.
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.
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.
