CHECKING BRAKE FLUID LEVEL

Make sure that a brake fluid level in reservoir tank is within the
standard (between MAX and MIN lines).

Visually check around reservoir tank for fluid leakage.

If the level is excessively low, check brake system for leakage.

Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Checking Brake LineNFS000RW
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (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.
Drain and RefillNFS000RX
CAUTION:

Refill with new brake fluid “DOT 3”.

Never reuse drained brake fluid.

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.

Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress brake pedal, loosen bleed valve, and gradually remove
brake fluid.

CAUTION:

Because vacuum hose contains a check valve, it must be
installed in the correct position. Refer to the stamp to con-
firm correct installation. Brake booster will not operate nor-
mally if the hose is installed in the wrong direction.

Insert vacuum hose at least 24 mm (0.94 in).

Do not use lubricating oil during assembly.

VISUAL INSPECTION
Check for correct assembly, damage and deterioration.
CHECK VALVE INSPECTION
Airtightness Inspection
Use a handy vacuum pump to check.

Replace vacuum hose assembly if vacuum hose and check
valve are malfunctioning.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000PY
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

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/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Procedures without Cowl Top CoverNFS000PZ
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000Q0

Recommended fluid is brake fluid “DOT 3”. Refer to MA-12, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted sur-
faces of body immediately wipe off then with cloth and then wash it away with water.

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use a flare nut wrench when removing flare nuts, and use a flare
nut crowfoot and torque wrench when tighten brake tube flare
nuts.

When installing brake tubes, be sure to check torque.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or battery
negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

Precautions for Brake ControlNFS000Q1

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and oil leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.
