PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

NFS000DS

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 Cover

NFS000HU

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

Precautions for Brake System

NFS000DT

●

Recommended fluid is brake fluid “DOT 3”. Refer to

MA-10, "Fluids and Lubricants"

●

Do not 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.

●

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

●

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

●

Use flare nut wrench when removing and installing brake tube.

●

When installing brake piping, be sure to torque.

●

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and control unit or battery cables.

●

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to

BR-30, "BRAKE BURNISHING PROCEDURE"

WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.

LEVEL CHECK

●

Make sure the fluid level in the sub-tank is within the standard
(between MAX and MIN lines).

●

Visually check around the reservoir tank and sub-tank for fluid
leakage.

●

If fluid level is excessively low, check brake system for fluid leak-
age.

●

If brake warning lamp remains illuminated after parking brake
pedal is released, check brake system for fluid leaks.

Drain and Refill

NFS000DZ

CAUTION:

●

Refill with new brake fluid “DOT3”.

●

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.

Connect a vinyl tube to bleed valve.

Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.

Turn ignition switch OFF and disconnect ABS actuator and elec-
tric unit (control unit) connector or battery cables.

Make sure there is no foreign material in the sub tank, and refill
with new brake fluid.

Disassembly

CAUTION:

Remove the reservoir tank only when absolutely necessary.

Using a flat-bladed screwdriver as shown in the figure, lift up the
tabs on the stopper cap and remove it from the master cylinder.
The piston inside the master cylinder might pop out when this is
done, so hold the stopper cap down at the same time.

Place the side flange of cylinder body with chamfering around
the pin insertion hole facing up, and firmly set master cylinder
assembly in a vise.

CAUTION:

●

When setting the master cylinder assembly with the vise,
be sure not to over-tighten.

●

When setting securing with a vise, use copper plates or
cloth to protect the flange.

Using a pin punch [commercial service tool: diameter approxi-
mately 4 mm (0.16 in)], remove mounting pins on the reservoir
tank.

Remove master cylinder assembly from vise.

Remove reservoir tank and grommet from cylinder body.

Using a flat-bladed screwdriver, push in the piston and remove
piston stopper from cylinder body.

Carefully pull the primary piston assembly straight out to prevent
cylinder inner wall from being damaged.

Tap flange using a soft block such as wood, and carefully pull
the secondary piston assembly straight out to prevent cylinder
inner wall from being damaged.

Inspection after Disassembly

Master cylinder

●

Check the inner wall of the cylinder for damage, abrasion, corrosion and pin holes.
Replace the master cylinder if any non-standard condition is detected.

Assembly

CAUTION:

●

Never use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

●

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and take care to avoid damaging parts with the assembly tools.

●

Do not drop parts. If a part is dropped, do not use it.

Apply brake fluid to cylinder inner wall body and contact surface
of the piston assembly. Then insert secondary piston assembly
and primary piston assembly into cylinder body in this order.

CAUTION:

●

Do not reuse primary and secondary piston assemblies.

●

Be sure to replace the assembly without disassembling
the new inner kit.

●

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.

Visually check the secondary piston slit through the tank boss
hole on the secondary side of the cylinder body, and insert the
piston stopper.

Holding down the primary piston with the stopper cap, push the
stopper cap claws so they are firmly into the cylinder grooves,
then install the stopper cap.

CAUTION:

Do not reuse the stopper cap.

Apply brake fluid to the grommet and install to the cylinder body.

CAUTION:

Do not reuse the grommet.

Master cylinder assembly is fixed in the vise as described in
“disassembly: step 2”.
