PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EFS0067U
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:
G 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.
G 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.
G 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.

On-Vehicle Service EFS005ZG
PEDAL STROKE
G When parking brake pedal is operated at specified force, make sure the stroke is within the specified num-
ber of notches. (Check it by listening and counting the ratchet clicks.)
Pedal force : 196 N (20 kg-f, 44 lb-f)
Pedal stroke : 5 to 6 notches
G If the pedal stroke is not within specification, perform the adjustment operation. Refer to PB-4, "ADJUST-
MENT" .
INSPECT COMPONENTS
G Make sure the components are attached properly (check for looseness, backlash, etc.).
G Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.
G Check cable for wear and damage, and replace if necessary.
G Check parking brake warning lamp switch for malfunction, and replace if necessary. Refer to DI-27, "Wir-
ing Diagram -- WARN --" .
ADJUSTMENT
1. Remove lower instrument panel LH using power tool. Refer to IP-12, "Instrument Lower Panel LH" .
2. Insert a deep socket wrench to rotate adjusting nut and loosen
the cable sufficiently. Then, return the pedal to the free height.
3. Remove wheel and tire from the vehicle using power tool.
4. Using wheel nuts, secure the disc to the hub and prevent it from
tilting.
WFIA0138E
5. Remove adjusting hole plug installed on the disc rotor. Rotate
the adjuster in direction "A" as shown, until the disc rotor is
locked, using a suitable tool. After locking, turn the adjuster in
the opposite direction by 5 or 6 notches.
6. Rotate the disc rotor to make sure there is no drag. Install the
adjusting hole plug.
7. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 294 N (30 kg-f,
66 lb-f).
b. Rotate adjusting nut with deep socket to adjust pedal stroke. PFIA0295E
NOTE:
Do not reuse the adjusting nut after removing it.
c. When parking brake pedal is operated at specified force, make sure the stroke is within the specified num-
ber of notches. (Check it by listening and counting the ratchet clicks.)
Pedal force : 196 N (20 kg-f, 44 lb-f)
Pedal stroke : 5 to 6 notches
d. With the pedal completely returned, make sure there is no drag on the rear brake.

Repair limit thickness "A" : 1.5 mm (0.059 in)
SBR021A
Drum Inner Diameter Inspection
G Check drum inner diameter.
Standard inner diameter (new) : 190 mm (7.48 in)
Wear limit of inner diameter : 191 mm (7.52 in)
Other Inspections
G Check shoe sliding surface for excessive wear and damage.
G Check anti-rattle pin for excessive wear and corrosion.
G Check return spring for sagging.
G Check that adjuster moves smoothly.
SBR768A
G Check either visually or with a vernier caliper to see if there is
any excessive wear, cracks, or damage inside the drum.
INSTALLATION
Installation is in the reverse order of removal, observing the following:
G Refer to PB-7, "Components" and apply brake grease to the specified points during assembly.
G There is a difference between the adjusters orientation from left
and right. Assemble the adjuster so the threaded part expands
when rotating it in the direction shown by the arrow.
G Shorten adjuster by rotating it.
G When disassembling the adjuster, apply PBC (Poly Butyl Cupry-
sil) grease or silicone based grease to the threads. Refer to MA-
9, "RECOMMENDED FLUIDS AND LUBRICANTS" .
G After replacing brake shoes or disc rotors, or if brakes do not
function well, perform break-in operation as follows.
1. Adjust the parking brake pedal stroke to the specified stroke. SFIA0153E
Refer to PB-4, "PEDAL STROKE" .
2. Perform break-in (drag run) operation by driving the vehicle under the following conditions:
Drive forward
G Vehicle speed approx. 40 km/h (25 MPH) set (forward)
G Parking brake operating force approx. 147 N (15 kg-f, 33 lb-f) set
G Distance approx. 100 m (328 ft)
3. After break-in operation, check lever stroke of the parking brake. Readjust if it is no longer at the specified
stroke.
G To prevent the lining from getting too hot, allow a cool off period of approximately 5 minutes after every
break-in operation.
G Do not perform excessive break-in operations, because it may cause uneven or early wear of the lining.
