DESCRIPTION
All dimensions indicated in the figures are actual.
When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.
When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
Measurements should be taken at the center of the mounting holes.
An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
The coordinates of the measurement points are the distances measured from the standard line of X, Y
and Z.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000ON
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.
WAR NING :
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 CoverNFS000OO
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000OP
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”.
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.
Use clean brake fluid, to clean or wash all parts of master cylinder and disc brake caliper, etc.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use flare nut torque wrench when installing brake tube.
When installing brake tube and hose, be sure to check torque.
Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
Burnish the brake contact surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low
mileage. Refer to BR-28, "
BRAKE BURNISHING PROCE-
DURE" (front disc brake), BR-34, "BRAKE BURNISHING PRO-
CEDURE" (rear disc brake).
WAR NING :
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

ADJUSTMENT
1. Loosen stop lamp switch and brake switch by turning it counter-
clockwise by 45
.
2. Loosen lock nut (A) on the input rod to rotate input rod for adjust-
ing brake pedal height to the specified one, and tighten lock nut
(A).
Refer to brake pedal height BR-6, "
Inspection and Adjustment" ,
specified torque BR-19, "
COMPONENTS" .
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With the pedal pulled and held by hand, press stop lamp switch
and brake switch until its threaded end contacts stopper.
4. With the threaded end of the stop lamp switch and brake switch
contacting the bracket, rotate the switch clockwise by 45
to
secure.
CAUTION:
Make sure that the clearance (C) between bracket and end
of stop lamp switch and brake switch is within the standard.
Refer to BR-6, "
Inspection and Adjustment" .
5. Check pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depression height when
depressed. Refer to BR-6, "
