Speedometer
*
[LG12700( ALL)01/95]
The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[LG12750(BEF )04/95]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when
the tires are changed will also ensure that the
speedometer retains the original factory-set
accuracy. NOTE: The conversion constant can
only be changedsix timesonce the vehicle
leaves the factory. Your Ford dealership service
personnel can change the conversion constant.
*
[LG12753(BEF )01/95]
Some vehicles are equipped with a vehicle speed
(MPH/km/h) limiting device that is contained
within the Powertrain Control Module (PCM).
The purpose of this device is to maintain peak
vehicle speed below a specified limit. (Vehicle
speed limits may vary based on engine
displacement).

[DR15300(B F )03/95]
When you come to a stop, do not downshift
through each gear. Disengage the clutch and use
the brake as necessary. Downshifting through
the gears decreases your vehicle's fuel economy.
*
[DR15400(B F )05/95]
RWARNING
Continued use of a damaged or worn
clutch, prolonged clutch slippage or
downshifting at excessive speeds can
result in a failure of the engine,
transmission or clutch components.
*
[DR15500(B F )03/91]
Transmission Function
*
[DR15600(B F )03/91]
Upshift at the speeds specified in the chart
available for your engine and transmission. All
forward gears are synchronized allowing you to
shift into them with your vehicle in motion. The
clutch pedal should be fully depressed when
shifting.
*
[DR15625(B F )04/94]
NOTE: Shifting during extremely low rpm's
can result in a momentary audible
rattle which disappears as vehicle
rpm's are increased. Shifting at higher
speeds will eliminate this sound.
*
[DR15700(B F )03/95]
Parking
*
[DR15800(B F )01/95]
To park your vehicle, apply the service brake
pedal, and shift into N (Neutral) while still
maintaining pressure on the service brake. Set
the parking brake fully. Shift into first and turn
off the ignition.

Driving on Snow or Ice
*
[DR21200(B F )10/90]
A four-wheel drive vehicle has advantages over
two-wheel drive vehicles in snow and ice but
can skid like any other vehicle. If so equipped,
keep the vehicle in four-wheel drive if icy or
slippery conditions exist.
*
[DR21300(B F )11/89]
Avoid sudden applications of power and quick
changes of direction on snow or ice. Apply the
accelerator slowly and steadily when starting
from a full stop.
[DR21312(B F )05/95]
All utility-type and Four-Wheel Drive vehicles
have special design and equipment features to
make them capable of performing in a wide
variety of off-road applications. Specific design
characteristics give them higher centers of
gravity than ordinary passenger cars.
*
[DR21325(B F )05/95]
RWARNING
All utility and four-wheel drive vehicles
are not designed for cornering at speeds
as high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns or abrupt
maneuvers in these vehicles.

Rear Drum Brakes
*
[DR22000(BEF )03/95]
The rear drum brakes are self-adjusting.
Automatic adjustment occurs when the brakes
are applied while ªbacking up.º If normal
operation does not include much backing, adjust
the brakes when they seem ªlow,º using the
procedure underIf Brakes Do Not Grip Well or
Pedal is Lowin this chapter.

[DR22025( F )03/91]
Rear Disc Brakes (F-Super Duty and
F-Series Stripped Chassis Only)
*
[DR22050( EFM)04/95]
The rear disc brakes are self-adjusting. They do
not require service other than periodic
lubrication of the caliper slide rails and
inspection for pad wear.
*
[DR22100( ALL)11/89]
Hydraulic Power Brakes
*
[DR22200(BEF )08/94]
The hydraulic brake system is made up of two
independent hydraulic circuits. One hydraulic
circuit supplies fluid to the front disc brakes and
the other hydraulic circuit supplies fluid to the
rear drum brakes. These two circuits are
supplied by a common hydraulic brake fluid
reservoir, with a fluid level sensor.
*
[DR22300( ALL)11/89]
The brake light in the instrument cluster will
light for low brake fluid in the common brake
fluid reservoir.
*
[DR22400( ALL)05/95]
RWARNING
An increase in pedal travel will result in
reduced braking capability. The brake
system should be checked immediately.

Rear Anti-lock Brakes
*
[DR22600( F )02/92]
Except for F-Super Duty and F-Series
Commercial and Motorhome Stripped Chassis,
F-Series Light Trucks are equipped with a Rear
Antilock Brake System. This system prevents at
least one and often both rear wheels from
locking up when the brakes are applied in a
panic stop, for example.
*
[DR22800( EF )07/94]
Even with the Anti-lock Brake System, you
should be careful when braking. Front brake
lock up on any surface, even on smooth
pavement causes loss of steering control. Heavy
braking on roads with loose surfaces such as
snow or gravel, or severe pavement irregularities
could also cause you to lose steering control of
your vehicle.
*
[DR22900( EF )05/95]
RWARNING
If the anti-lock brake system warning
light remains on or comes on while
driving, have the braking system checked
by a qualified service technician as soon
as possible.
*
[DR22902( EF )05/95]
NOTE: If a fault occurs in the anti-lock
system, and the brake warning light is
not lit, the anti-lock system is disabled
but normal brake function remains
operational.

[DR23100( F )11/89]
If Brakes Do Not Grip Well or Pedal is
ªLowº (F-150/350 Only)
*
[DR23200(BEF )11/89]
If brakes do not grip well, it may indicate the
rear drum brakes need adjustment. To do this,
drive the vehicle in reverse at 5 mph (8 km/h)
on level, dry pavement. Stop the vehicle by
firmly applying the brakes. Repeat this
procedure four or five times.

*
[DR23250( ALL)11/89]
If during normal operation the brake pedal
seems ªlowº, it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
*
[DR23300( ALL)02/95]
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes annoyingly loud or increases
significantly in frequency of occurrence, return
the vehicle to your dealer for inspection.
*
[DR23400(BEF )11/89]
RWARNING
Modifications to the suspension spring
rates and/or vehicle ride height may
adversely affect vehicle stopping ability.

Perform the self-adjustment procedure
described underIf Brakes Do Not Grip Well or
Pedal is ªLow.º
*
[DR23800(BEF )05/95]
If pull occurs during the first 500 miles
(800 km), make 10 moderately fast stops from
40 mph (65 km/h) and then perform the
self-adjustment procedure above. It may be
necessary to repeat this operation to properly
seat new brake linings and pads.
*
[DR24000( ALL)01/93]
Stopping Distances
*
[DR24100( ALL)11/89]
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.

Applying the Brakes
*
[DR24300( ALL)05/95]
Apply the brake pedal gradually. Use the
ªsqueezeº technique Ð push on the brake pedal
with a steadily increasing force. This allows the
wheels to continue to roll while you are slowing
down, which lets you steer properly.
*
[DR24400( ALL)05/95]
RWARNING
Do not drive with your foot resting on the
brake pedal. This will increase your
vehicle's stopping distance and may also
cause brake damage.
*
[DR24500( ALL)05/95]
RWARNING
If you are driving down a long or steep
hill, shift to a lower gear. Do not apply
your brakes continuously, as they may
overheat and become less effective.
*
[DR24600( ALL)03/95]
Using the Parking Brake
*
[DR24650(BEF )01/95]
The parking brake should be used whenever you
park your vehicle.
*
[DR24800(B F )12/91]
The parking brake pedal is suspended just below
the bottom of the instrument panel to the left of
service brake and/or clutch pedals. To set the
parking brake while parking your vehicle, press
the brake pedal with your right foot and hold it
while you push the parking brake pedal down
firmly and fully with your left foot.
