2004 FORD F650 parking brake

•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level.
•At temperatures of–20°C(–4°F) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of–29°C (-20°F) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
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 insist on
using a winter front, the device should have a permanent opening of at
least 774 sq. cm (120 sq in.) directly in line with the fan hub.

•Operate in a gear that will permit an engine speed not in excess of the
maximum governed speed or high-idle RPM (no load).
All vehicles have blind spots. To reduce the risk of severe injury
or property damage, never move your vehicle to the side or rear
or change lanes without being sure your way is clear on both sides and
to your rear.
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 assure
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 assure that the intended path is clear.
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.
When parking your vehicle, do not leave the transmission in
gear; if the key is in the ON position and the vehicle rolls, then
engine could start. Failure to follow these instructions could result in
an unattended vehicle moving, possibly causing personal injury or
property damage.

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.
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.
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.
Burnish procedure (hydraulic brakes with park lever only)
For optimal performance of a new parking brake system/new linings
perform the following procedure:
1. While driving the vehicle at 16 km/h (10 mph) apply the parking brake
(with applicable force to set to approximately 18 kg [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.

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 prevent the vehicle from moving.
Unexpected and possibly sudden vehicle movement may occur if
these precautions are not taken.

equipped with automatic brake
adjusters. Automatic adjustment
occurs during brake applications.
Inspect brakes for proper
adjustment at the intervals listed in
the vehicle Service Maintenance
Guide.
Emergency air brake
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system will function for emergency
stopping. These systems are all controlled by the brake pedal in the
same manner as for normal stops.
Do not continue to operate the vehicle with a failure of one of
the systems. Take the vehicle to your dealer for service
immediately.
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

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 (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 2400 transmission) or P
(Park) (Allison 2400
transmission). Use of wheel
chocks is also recommended in
hilly or off-road usage.
