PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000LN
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 CoverNFS000LO
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000TE

Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.

Recommended fluid is brake fluid “DOT 3”. MA-12, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

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

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

Use a flare nut crowfoot and torque wrench when installing
brake tube.

When installing brake piping, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
negative terminal.

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-24, "
Brake Burnishing Procedure" (Front disc
brake), BR-30, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:

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

FRONT DISC BRAKE
Revision: 2006 July 2007 FX35/FX45

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, suspend cylinder body with wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Keep rotor clean, from brake fluid.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer to BR-24, "
Brake Burnishing Procedure" .
Removal and Installation of Brake PadNFS000MB
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow (shown in the fig-
ure) so as not to deform it.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) or silicone-based grease to the
both sides of inner shim and outer shim, install inner shim and
inner shim cover to inner pad, and outer shim and outer shim
cover to outer pad.
2. Apply PBC (Poly Butyl Cuprysil) or silicone-based grease to pad contact surface on pad retainers, and install pad retainers and
pads to torque member.
CAUTION:
Inner pad and outer pad have pad-return mechanism on
upper side of pad retainer. When installing pad to torque
member, be sure to install pad return lever to pad wear sen-
sor securely.
3. Install cylinder body to torque member. CAUTION:
When replacing pads with new ones, press in piston until pads can be installed. In this case, care-
fully monitor brake fluid level in reservoir tank because brake fluid will return to master cylinder
reservoir tank.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-19, "
Components" .
5. Secure disc rotor with wheel nuts. Depress brake pedal a few times until it gets a responsive touch.
6. Check brake for drag.
7. Install tires to vehicle.
Removal and Installation of Brake Caliper AssemblyNFS000MC
REMOVAL
1. Remove tires from vehicle with power tool.
2. Fasten disc rotor using wheel nut.
3. Drain brake fluid. Refer to BR-9, "

"Components" .
CAUTION:
Before installing torque member to vehicle, wipe oil and grease on washer seats on steering
knuckle and mounting surface of torque member.
3. Install a projection of brake hose metal fitting by aligning with protrusions on cylinder body, and tighten union bolts to the specified torque. Refer to BR-19, "
Components" .
CAUTION:

Do not reuse copper washer for union bolts.

Assemble brake hose securely on caliper assembly.
4. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-10, "
Bleeding Brake
System" .
5. Install tires to vehicle.
Disassembly and Assembly of Brake Caliper AssemblyNFS000MD
NOTE:
Do not remove torque member, brake pads, shims, shim covers and pad retainers, when disassembling or
assembling cylinder body.
DISASSEMBLY

Revision: 2006 July 2007 FX35/FX45
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the specification. Refer to FA X - 4 , "
WHEEL
BEARING INSPECTION" (2WD models), FA X - 1 0 , "WHEEL
BEARING INSPECTION" (AWD models).
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by
one hole.
4. If runout is still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent).
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
Brake Burnishing ProcedureNFS000OD
Burnish brake pad contact surfaces of disc rotor according to following procedure after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:

Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Measurement point
: At a point 10.0 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.04 mm (0.0016 in) or less
