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.

[DR22500( F )10/94]
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.
*
[DR23500(BEF )07/92]
If Brakes Pull
*
[DR23600(BEF )07/92]
q
Check tire pressure
*
[DR23700(BEF )07/92]
q
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.

[DR24200( ALL)01/95]
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.

Parking Brake
*
[DR24950(B F )03/95]
RWARNING
When parking, do not use the gearshift in
place of the parking brake. Turn the key
to LOCK whenever you leave your
vehicle. Always set the parking brake
fully and make sure that the gearshift is
securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual
transmission). Never leave your vehicle
unattended while it is running. If you do
not take these precautions, your vehicle
may move unexpectedly and injure
someone.
[DR24970(B F )05/95]
When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.

RWARNING
Do not leave the vehicle unattended with
the transfer case in the N (Neutral)
position. Always set the parking brake
fully and turn off the ignition when
leaving the vehicle.
*
[DR25000(B FM)03/93]
To release the parking brake, press the service
brake pedal with your right foot and pull the
parking brake release lever.
*
[DR25050( ALL)01/93]
RWARNING
If the parking brake is fully released, but
the Brake System light remains on, have
the brakes checked immediately. They
may not be working properly.
*
[DR25100( ALL)01/95]
The parking brake is not designed to stop a
moving vehicle, but you can use the parking
brake to stop your vehicle in an emergency if
the normal brakes fail. However, since the
parking brake applies only the rear brakes, the
stopping distance will increase greatly and the
handling of your vehicle will be adversely
affected.

Tips for Safe Driving
*
[DR25301( ALL)05/95]
As with any new vehicle, yours may drive and
handle differently from your previous vehicle.
Use care until you become accustomed to its
various features and driving characteristics.
*
[DR25350( ALL)03/95]
Operate your vehicle within reasonable limits.
Sudden acceleration, deceleration, turning, or
combinations of these maneuvers can cause a
vehicle to behave differently than anticipated.

Speed limiter
*
[DR26652(BEF )03/94]
All models are equipped with an electronic
engine control system (EEC) which limits the
maximum engine speed and thus road speed in
top gear. Vehicle operation is normal since the
controlled maximum speed is above posted
highway speeds in North America.

Drive cautiously on wet or snowy roads:
*
[DR26850( ALL)03/95]
q
Do not quickly move the steering wheel
unless necessary.
*
[DR26901( ALL)01/95]
q
Drive slower than you normally would.
*
[DR26951( ALL)01/95]
q
Give your vehicle more distance to stop.
*
[DR27025( ALL)07/94]
q
To stop on ice, shift to Neutral below 10 mph
(16 km/h) and gently pump brakes. (Except
with 4WAL)
*
[DR27050( ALL)02/93]
q
Consider using one of the lower gears.
*
[DR27101(B F )05/91]
q
For 4x4 vehicles, engage 4WD, and try to
drive slowly away.
*
[DR27150(B F )05/95]
RWARNING
To avoid losing control on slippery roads,

[DR27350(B F )06/94]
RWARNING
The rear antilock brake system may not
prevent brake lock-up on extremely
slippery surfaces. Rear brake lock-up may
also occur while driving in four-wheel
drive because the transfer case couples the
front and rear axles together.
*
[DR27450(BEF )03/95]
Traction-Lok Rear Axle (If equipped)
*
[DR27501(BEF )03/95]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.
*
[DR27550(BEF )03/93]
Extended use of other than matching size tires
on a Traction-Lok rear axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.
*
[DR27601(BEF )05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

[DR27651( ALL)01/95]
High water
*
[DR27675( ALL)06/92]
Never attempt to cross water that is fast flowing
or of unknown depth.
*
[DR27701( ALL)05/90]
Do not drive through flooded areas unless you
are sure that the water is below the bottom of
the wheel hubs.
*
[DR27750( ALL)04/94]
If you must drive through high water, drive
slowly. You may have limited traction or wet
brakes, so allow extra stopping distance because
your vehicle will not stop as quickly as usual.

*
[DR27801( ALL)01/95]
After you drive through the standing water,
apply your brakes gently several times as your
vehicle moves slowly. This helps to dry the
brakes.
*
[DR27820( ALL)07/94]
NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.
*
[DR27825( ALL)03/93]
NOTE: All rear axle lube quantities must be
replaced every 100,000 miles
(160,000 km) or if the axle has been
submerged in water. Otherwise, the
lube should not be checked or changed
unless a leak is suspected or repair
required.
*
[DR27850( ALL)11/89]
Rocking the vehicle
*
[DR27901(B F )05/90]
For 4x4 vehicles, engage 4WD LOW, when the
vehicle gets stuck and try to drive away.
*
[DR27950( ALL)05/95]
If your vehicle gets stuck (for example, in mud
or snow), you may rock it out of the spot. Shift
in a steady rhythm between forward and reverse
gears. Allow the transmission to fully engage,
then press lightly on the accelerator. Do not rock
the vehicle for more than a few minutes. This
may overheat the engine and transmission,
causing damage to both. In addition, other
vehicle systems and components may also be
damaged.
*
[DR27975( ALL)05/95]
RWARNING
Do not spin the wheels at over 35 mph
(56 km/h). The tires may fail and injure a
passenger or bystander.
