1999 FORD RANGER ABS

BRAKES
Your service brakes are self-adjusting. Refer to the ªService Guideº for
scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Rear anti-lock brake system (RABS)
Rear Anti-lock Brake System (RABS) is standard equipment on this
vehicle. RABS is designed to help you maintain directional stability in
emergency stopping situations. With RABS, the rear brakes are kept from
locking during panic stops; however, the front wheels can lock because
they are not controlled by RABS.
A clicking noise and slight pedal pulsation during RABS braking events
indicates the RABS is functioning. Pedal pulsation coupled with clicking
noise while braking under panic conditions on loose gravel, wet or snowy
roads is normal and indicates proper functioning of the vehicle's RABS. If
the vehicle has continuous vibration or shudder in the steering wheel
while braking, the vehicle should be inspected by a qualified service
technician.
The RABS operates by detecting the onset of rear wheel lockup during
brake applications and compensating for this tendency.
RABS warning lamp
TheABSwarning lamp in the instrument cluster illuminates if a RABS
fault is detected. Have your vehicle serviced as soon as possible.
Normal braking is still effective
unless the BRAKE warning lamp is
also illuminated.

Using RABS
²In an emergency, applying full pressure may cause the front wheels to
lock.If the front brakes lock, the vehicle cannot be steered.Yo u
should apply the brakes with steadily increasing force, as if
ªsqueezingº the brakes. If you feel the front wheels begin to lock,
momentarily release the pedal and repeat the ªsqueezeº technique.
²We recommend that you familiarize yourself with how the RABS
performs. However, avoid unnecessary risks.
Four-wheel anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system. If the vehicle has continuous vibration or shudder
in the steering wheel while braking, the vehicle should be inspected by a
qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensating for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking with loss of front braking traction.
ABS warning lamp
The
ABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
Driving
104

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 with parking brake
released. (If your 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, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.

When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button to resume speeds over 50 km/h (30
mph).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
D (Drive).
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
Allow more stopping distance and drive slower than usual. Consider
using one of the lower gears.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
Extended use of other than the manufacturer's specified 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.
To avoid injury, never run the engine with one wheel off the
ground, such as when changing a tire.
