Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006DL
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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.
lImproper 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.
lDo 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 Brake SystemEFS005SD
lClean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe 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.
lTo clean or wash all parts of master cylinder, disc brake caliper, wheel cylinder, use new brake fluid.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse a flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lAlways tighten brake lines to the specified torque when install-
ing.
lBefore working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
the battery cables.
lBurnish the new brake surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer toBR-29, "
BRAKE BURNISHING PROCEDURE".
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.SBR820BA

(between MAX and MIN lines).
lVisually check around the reservoir tank for fluid leakage.
lIf fluid level is excessively low, check brake system for fluid leak-
age.
lRelease parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillEFS005SJ
CAUTION:
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe off them and wash it away with water.
lBefore working, disconnect connector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the pedal. Repeat the same work for each
wheel.
5. Bleed air. Refer toBR-11, "
Bleeding Brake System".

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air- borne
particles or other materials.
CAUTION:
lWhile removing cylinder body, do not depress brake pedal because piston will pop out.
lIt is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
lDo not damage piston boot.
lIf any shim is subject to serious corrosion, replace it with a new one.
lAlways replace shim as a set when replacing brake pad.
lKeep rotor out of brake fluid.
Removal and Installation of Brake PadEFS005T0
REMOVAL
1. Remove tyre from vehicle.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire. Remove pad assembly and pad retainer from torque member.
CAUTION:
When removing the pad retainer from the torque member, lift it in the direction indicated by the
arrow in the figure so that it does not deform.
INSTALLATION
1. Install inner shim to inner pad, and outer shim to outer pad.
2. Install pad retainers and pad assembly to torque member.
3. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
CAUTION:
lWhen installing pad retainer, attach it firmly so that it
does not flat up higher than torque member, as shown in
the figure.
lIn the case of replacing pad with new one, check a brake
fluid level in the reservoir tank because brake fluid
returns to master cylinder reservoir tank when pressing
piston in.
4. Install lower sliding pin bolt and tighten to the specified torque. Refer toBR-24, "
Components".
5. Check front disc brake for drag.
6. Install tyre to vehicle.

Precautions for Brake SystemEFS005TG
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.If brake fluid is splashed, wipe it off and flush area
with water immediately.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lBrake system is an important safety part.If a brake fluid leak is
detected, always disassemble the affected part.If a malfunction
is detected, replace part with new one.
lBefore working, turn ignition switch OFF and disconnect con-
nector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
lWhen installing brake tube and hose, be sure to torque.
WARNING:
Clean brake pads and shoes with a waster cloth, then wipe with
a dust collector.
Precautions for Brake ControlEFS005TH
lJust after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
lWhen an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.
lIf tyre size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
lIf there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
lIf aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

FunctionsEFS005TK
ABS
lThe Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheels lock. Maneuverability is also
improved for avoiding obstacles.
lElectrical system diagnosis by CONSULT-II is available.
EBD
lElectronic Brake Distributor is a function that detects subtle slippages between the front and rear tyre dur-
ing braking, and it improves handling stability by electrically controlling the brake fluid pressure which
results in reduced rear tyre slippage.
lElectrical system diagnosis by CONSULT-II is available.
Operation That Is Not “System Error”EFS005TL
ABS
lWhen starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating noise
may be heard from engine room. This is a normal states of the operation check.
lDuring ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionEFS005TM
ABS, EBD SYSTEM
In case of electrical malfunction with ABS, ABS warning lamp will turn on. In case of electrical incidents with
EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of following
conditions of Fail-Safe function.
1. For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
ABS system.
NOTE:
ABS self-diagnosis sound may be heard.That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
2. For EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.
