q See EL section, ``POWER SUPPLY ROUTING'' for power distribution circuit.
q See EL section for NATS information and wiring diagram.
When you perform trouble diagnoses, read GI section, ``HOW TO FOLLOW FLOW
CHART IN TROUBLE DIAGNOSES'' and ``HOW TO PERFORM EFFICIENT DIAGNOSIS
FOR AN ELECTRICAL INCIDENT''.

PRECAUTIONS AND PREPARATION
Supplement Restraint System (SRS)
``AIRBAG'' and ``SEAT BELT Pre-tensioner''
The Supplemental Restraint System ``Air Bag'' and ``Seat Belt Pre-tensioner'', used along with a seat belt,
help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of an air bag module (located in the center of the steering wheel
and on the instrument panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sen-
sor unit, warning lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used
along with the seat belt help to reduce the risk or severity of injury to the driver and front passenger in a
side collision. The supplemental side air bag consists of air bag modules (located in the outer side of front
seats), satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal
collision), wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision).
Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
q To avoid rendering the SRS inoperative (which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation), all maintenance must be per-
formed by an authorized NISSAN dealer.
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ``SEAT BELT-TENSIONER'' connector) can be
identified with yellow harness connector and with yellow harness protector or yellow insulation
tape before the harness connectors.
Precautions
q Use only ``DOT 4'' fluid from a sealed container.
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
q To clean master cylinder parts, disc brake caliper parts
or wheel cylinder parts, use clean brake fluid.
Commercial service tool
q Never use mineral oils such as Petrol or kerosene. They
SBR686C
will ruin rubber parts of hydraulic system.
q Use flare nut wrench when removing and installing brake
tubes.
q Always torque brake lines when installing.
q Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads or linings, or if a
soft pedal occurs at very low speed. Refer to ``Brake
Burnishing Procedure'', ``Check and Adjustment''.
WARNING:
q Clean brakes with a vacuum dust collector to minimize
risk of health hazard from airborne materials.
q Avoid prolonged and repeated skin contact with brake
fluid.
q Wear protective clothing, including impervious gloves.
q Where there is a risk of eye contact, eye protection
should be worn -- for example chemical goggles or face
shield.

CHECK AND ADJUSTMENT
Checking Brake Fluid Level
q Check fluid level in reservoir tank. It should be between Max.
and Min. lines on reservoir tank.
MAX. q If fluid level is extremely low, check brake system for leaks.
q If brake warning lamp comes on and fluid level is above
``MIN'' mark, check brake fluid level switch and parking brake
MIN. switch.
NBR141
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
ABR159
Changing Brake Fluid
CAUTION:
q Refill with new brake fluid ``DOT 4''.
q Always keep fluid level higher than minimum line on
reservoir tank.
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
SBR419C
1. Connect a vinyl tube to each air bleeder valve.
2. Drain brake fluid from each air bleeder valve by depressing
brake pedal.
3. Refill until new brake fluid comes out of each air bleeder
valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to ``Bleeding Brake System'', BR-7.
Brake Burnishing Procedure
Burnish the brake contact surfaces according to the following
procedure after refinishing or replacing rotors, after replacing
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31
MPH).
BR-6
CHECK AND ADJUSTMENT
Brake Burnishing Procedure (Cont'd)
2. Use medium brake pedal/foot effort to bring the vehicle to a
complete stop from 50 km/h (31 MPH). Adjust brake pedal/
foot pressure such that vehicle stopping time equals 3 to 5
seconds.
3. To cool the brake system, drive the vehicle at 50 km/h (31
MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the bur-
nishing procedure.
Bleeding Brake System
CAUTION:
q Carefully monitor brake fluid level at master cylinder
during bleeding operation.
q If master cylinder is suspected to have air inside, bleed
air from master cylinder first. Refer to ``Installation'',
``MASTER CYLINDER'', BR-14.
q Fill reservoir with new brake fluid ``DOT 4''. Make sure it
is full at all times while bleeding air out of system.
q Place a container under master cylinder to avoid spillage
SBR995 of brake fluid.
q For models with ABS, turn ignition switch to the OFF
position and disconnect ABS fuse or battery cable.
q Bleed air in the following order:
RHD models
Left rear brakeRight front brakeRight rear brakeLeft
front brake
LHD models
Right rear brakeLeft front brakeLeft rear brakeRight
front brake.
1. Connect a transparent vinyl tube to air bleeder valve.
SBR419C 2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to
release air.
4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2. through 5. until clear brake fluid comes out
of air bleeder valve.
7. Tighten air bleeder valve.
