brake sensor NISSAN FRONTIER 1997 D22 / 1.G Owners Manual

The brake system has two separate hydrau-
lic circuits. If one circuit develops a problem,
you will still have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and the stopping distance will be
longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster,
and reduce gas mileage.
To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions
or sudden acceleration could cause the
wheels to skid and result in an acci-
dent.
Normal Operation
The rear anti-lock brake system does not
operate at speeds below 3 to 6 MPH (5 to 10
km/h). (The speeds vary according to road
conditions.)
When driving in the 2-wheel drive mode, the
rear anti-lock brake system controls the rear
wheels so they will not lock when braking
abruptly or when braking on a slippery road.
Thus, difficult steering and swerving of the
vehicle due to locked rear wheels is mini-
mized. The system detects the rear wheel
rotation rate and electronically controls the
pressure applied to each rear brake. Slight
vibration on the brake pedal accompanied
by noise usually occurs while the ABS sys-
tem is operating. Such vibration and noise
encountered during abrupt braking is not a
problem, but indicates that the system is
functioning.
Even with the rear anti-lock brake sys-
tem, your front wheels can still lock. If
this happens, release the brake pedal
slightly and then reapply pressure.

The rear anti-lock brake system consists of
an electronic sensor and two hydraulic so-
