PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS00001
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 Battery ServiceNFS00002
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Procedures without Cowl Top CoverNFS000HT
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS00003

Recommended fluid is brake fluid “DOT 3”. Refer to MA-11, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the paint, so
if it does come in contact, immediately wipe area and wash off with water.

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

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

2. Attach the attachment in the inner kit to the reservoir cap as
shown in the figure.
CAUTION:
When attaching the attachment to the reservoir cap, make
sure it is pointing in the right direction.
3. Place the side of the cylinder body with chamfering around the
pin insertion hole facing up, and secure the master cylinder
assembly with a vise.
CAUTION:

Tighten without letting the pin securing the reservoir tank
and cylinder body come in contact with the pin insertion
hole of the reservoir tank.

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

When securing in a vise, use copper plates or cloth to
protect the flange.
4. Using a pin punch [commercial service tool: diameter approx. 4
mm (0.16 in)], remove mounting pin on the reservoir tank.
5. Remove master cylinder assembly from the vise.
6. Remove reservoir tank and grommet from cylinder body.
7. Using a Phillips flat-bladed screwdriver, push in the primary pis-
ton and remove the piston stopper from the cylinder body sec-
ondary-side tank boss hole.
8. Carefully pull the primary piston assembly straight out to prevent
cylinder inner wall from being damaged.
9. 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.

NOTE:
Attach the reservoir tank in the orientation shown in the figure.
8. Using a pin punch [commercial service tool: diameter Approx. 4
mm (0.16 in)], attach the reservoir tank mounting pin so that the
attachment side and the opposite side are identical.
CAUTION:
Do not reuse reservoir tank and mounting pin.

CAUTION:

While working, cover the primary piston rod with cloth to prevent it from being damaged.

Only remove the reservoir tank when absolutely necessary.
1. Place the side of the cylinder body with chamfering around the
pin insertion hole up, and secure the cylinder body flange sec-
tion with a vise as shown in the figure.
CAUTION:
When securing in a vise, use copper plates or cloth to pro-
tect the flange.
2. Using a pin punch [commercial service tool: diameter Approx 4
mm (0.16 in)], remove the reservoir tank mounting pin.
3. Remove master cylinder assembly from the vise.
4. Remove reservoir tank and grommet from cylinder body.

FRONT DISC BRAKE
Revision: 2006 November2007 350Z
Removal and Installation of Brake Pad (With Brembo Calipers)NFS0000W
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove the clip from the pad pin.
3. Remove the pad pin while holding down the cross spring, then
remove the cross spring from the caliper.
4. Using pliers, remove the pad from the caliper.
HOW TO APPLY GREASE TO THE BRAKE PAD
Pad Side
Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease
about 0.5 g (0.018 oz) per surface equally to back plate side of Inner
Pad and Outer Pad. (Refer to the figure.)
CAUTION:
Make sure no foreign matter attaches itself to the grease.
INSTALLATION
1. Insert the piston to the position where the pad is attached.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.
CAUTION:
By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.
