On-Vehicle ServiceAFS001TJ
PEDAL STROKE

When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the stroke is
within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
INSPECT COMPONENTS

Make sure the components are attached properly (check for looseness, backlash, etc.).

Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.

Check cable for wear and damage, and replace if necessary.

Check parking brake warning lamp switch for malfunction, and replace if necessary.
ADJUSTMENT

To perform adjustment operations, remove tire from the vehicle with power tool.
1. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, return pedal.
2. Using wheel nuts, fix disc to hub and prevent it from tilting.
3. Remove adjusting hole plug installed on disc. Using a flat-
bladed screwdriver, turn Adjuster in direction A as shown in the
figure until disc rotor is locked. After locking, turn adjuster in the
opposite direction by 5 or 6 notches.
4. Rotate disc rotor to make sure there is no drag. Install adjusting
hole plug.
5. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg,
11 0 l b ) .
b. Rotate adjusting nut with deep socket to adjust pedal stroke.
CAUTION:
Do not reuse adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the stroke is
within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With pedal completely returned, make sure there is no drag on rear brake.Pedal stroke : 4 − 5 notches

PARKING BRAKE SHOE
Revision: 2004 November 2004 FX35/FX45
INSPECTION AFTER REMOVAL
Lining Thickness Inspection

Check thickness of lining.
Drum Inner Diameter Inspection

Check drum inner diameter.
Other Inspections

Check shoe sliding surface for excessive wear and damage.

Check anti-rattle pin for excessive wear and corrosion.

Check return spring for sagging.

Check adjustor for rough operation.

Check either visually or with a vernier caliper to see if there is
any excessive wear, cracks, or damage inside drum.
INSTALLATION
Be careful of the following:

Refer to “Component Parts Location” and apply brake grease to the specified points during assembly.

Assemble adjuster so that threaded part expands when rotating
it in the direction shown by the arrow.

Shorten adjuster by rotating it.

When disassembling adjuster, apply PBC (Poly Butyl Cuprysil)
grease or silicone based grease to the threads.

After replacing brake shoes or disc rotors, or if brakes do not
function well, perform break-in operation as follows.
1. Adjust parking brake pedal stroke to the specified stroke.
2. Perform parking brake break-in (drag run) operation by driving
the vehicle under the following conditions:
3. After break-in operation, check lever stroke of parking brake. Readjust if it is no longer at the specified
stroke.

To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every
break-in operation.

Do not perform excessive break-in operations, because it may cause uneven or early wear of lining.Standard thickness (A) : 3.2 mm (0.126 in)

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the illustra-
tion below.
CAUTION:

Do not pull the harness or wires when disconnecting the connector.

Be careful not to damage the connector support bracket when disconnecting the connector.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AGS000GO
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 Necessary for Steering Wheel Rotation After Battery DisconnectAGS000L4
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Steering SystemAGS000GP

Before disassembly, thoroughly clean the outside of the unit.

Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.

For easier and proper assembly, place disassembled parts in order on a parts rack.
