INSPECTION AFTER REMOVAL

Lining Thickness Inspection

• Check the thickness of the shoe lining.

Drum Inner Diameter Inspection

• Check the drum inner diameter.

Other Inspections

• Check the shoe sliding surface for excessive wear and damage.

• Check the shoe hold-down pins for excessive wear and corrosion.

• Check the upper and lower return springs for sagging.

• Check the adjuster for rough operation.

• When disassembling the adjuster, apply PBC (Poly Butyl Cuprysil) grease or equivalent to the adjuster

threads.

• Check either visually or with a vernier caliper for any excessive wear, cracks, or damage inside the drum.

INSTALLATION

Installation is in the reverse order of removal.

• Apply brake grease to the back plate at the specified points during installation.

• Install the adjuster so that the threaded part expands when rotating

it in the direction shown by the arrow.

• Shorten adjuster by rotating it in the opposite direction.

NOTE:

After replacing the shoes or disc rotors, or if parking brake does not

function properly, perform the break-in operation as follows.
1. Adjust the parking brake pedal stroke to specification. Refer to

2. Perform the parking brake break-in operation by driving the vehicle forward under the following conditions:

• Maintain vehicle speed 40 +10, -0 km/h (25 +6, -0 MPH) moving forward.

• Apply the parking brake pedal with an operating force of 260 +59, -0 N-f (26.5 +6.0, -0 kg-f, 58.4 +13.3,

-0 lb-f).

• Apply the parking brake pedal for a period of 10 +5, -0 seconds before releasing.

CAUTION:

• To prevent the linings 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 the

linings.

3. After the break-in operation, check parking brake pedal stroke. Readjust as necessary if it is not within the

specified stroke. Refer to

PB-5, "On-Vehicle Service"

.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000006247487

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 SR 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 performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000006247488

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT-III 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 NATS, an electrically controlled steering lock mech-

anism 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-III.

Precaution for Power Generation Variable Voltage Control System

INFOID:0000000006247489

CAUTION:

For this model, the battery current sensor that is installed to the negative battery cable measures the

charging/discharging current of the battery and performs various engine controls. If an electrical com-

ponent is connected directly to the negative battery terminal, the current flowing through that compo-

nent will not be measured by the battery current sensor. This condition may cause a malfunction of

the engine control system and battery discharge may occur. Do not connect an electrical component

or ground wire directly to the battery terminal.
