Checking BrakeSystem

Check brakefluidlines andparking brakecables forimproper
attachment andforleaks, chafing, abrasions, deterioration, etc.

Removal andInstallation
CAUTION:
• Before removing therear suspension assembly,disconnect
the ABS wheel sensor fromtheassembly. Failuretodo so
may result indamage tothe sensor wiresandthesensor
becoming inoperative.

• Remove suspension assembly.
1. Disconnect brakehydraulic linesandparking brakecableat
toggle lever.(Models withdrum brakes.)
• Drain brake fluidbefore disconnecting brakelines.
2. Disconnect parkingbrakecablefromcaliper andremove
brake caliper androtor. (Models withdiscbrakes.)

Suspend caliperassembly withwire soasnot tostretch brake
hose.
Be careful nottodepress brakepedal, orpiston willpop out.
Make surebrake hoseisnot twisted.

3. Using atransmission jack,raise torsion beamalittle, and
remove nutsandbolts fromthetrailing arm,shock absorber
assembly (lowerside)andlateral link.
4. Lower transmission jack,andremove suspension.
5. Remove luggagecompartment trim.Refer toBT section.
6. Remove strutsecuring nuts(upper side).Thenpulloutstrut
assembly.
• Install suspension assembly.

CAUTION: Refill withnewbrake fluid"DOT
3".

Never reusedrained brakefluid.

1. Attach torsion beam,attrailing armandlateral link,tovehi-
cle. Donot tighten boltsatthis time.
2. Using atransmission jack,place lateral linkand control rod
horizontally againsttorsionbeam.Tighten laterallinkon
vehicle.
3. Attach shockabsorber assembly tovehicle. Thentighten the
lower sideofshock absorber assembly.
4. Lower torsion beamtofully extended position.Remove
transmission jackandtighten torsion beam,attrailing arm,
to specified torque.RefertoRA-8.
5. Install brakehydraulic linesandtighten flarenuts.

PRECAUTIONSANDPREPARATION
Precautions
SUPPLEMENTAL RESTRAINTSYSTEM(SRS)"AIRBAG"
(Dual AirBag System)

The Supplemental RestraintSystem"AirBag" usedalong withaseat belt,helps toreduce therisk or
severity ofinjury tothe driver andfront passenger inafrontal collision. TheSupplemental Restraint
System consists ofair bag modules (locatedinthe center ofthe steering wheelandonthe instrument
panel onthe passenger side),adiagnosis sensorunit,warning lamp,wiring harness andspiral cable.
Information necessarytoservice thesystem safelyisincluded inthe
RSsection
ofthis Service Manual.

WARNING: • Toavoid rendering theSRS inoperative, whichcouldincrease therisk ofpersonal injuryordeath
in the event ofacollision whichwould resultinair bag inflation, allmaintenance mustbeperformed
by an authorized NISSANdealer.
• Improper maintenance, includingincorrectremovalandinstallation ofthe SRS, canlead topersonal
injury caused byunintentional activationofthe system.
• Donot use electrical testequipment onany circuit related tothe SRS unless instructed tointhis
Service Manual. SRSwiring harnesses arecovered withyellow insulation eitherjustbefore the
harness connectors orfor the complete harness,foreasy identification.

STEERINGSYSTEM
• Before disassembly, thoroughlycleantheoutside ofthe unit.
• Disassembly shouldbedone inaclean workarea. Itis important toprevent theinternal partsfrom
becoming contaminated bydirt orother foreign matter.
• Place disassembled partsinorder, onaparts rack,fore"asier andproper assembly.
• Use nylon cloths orpaper towels toclean theparts; common shopragscanleave lintthat might
interfere withtheir operation.
• Before inspection orreassembly, carefullycleanallparts withageneral purpose, non-flammable
solvent.
• Before assembly, applyacoat ofrecommended ATF*tohydraulic parts.Vaseline maybeapplied to
O-rings andseals. Donot use any grease.
• Replace allgaskets, sealsandO-rings. Avoiddamaging O-rings,sealsandgaskets duringinstalla-
tion. Perform functional testswhenever designated.

Bleeding Hydraulic System

1. Raise frontendofvehicle untilwheels areclear ofthe
ground.
2. Add fluid intooiltank tospecified level.Thenquickly turn
steering wheelfullytoright andleftand lightly touchsteer-
ing stoppers.
Repeat steering wheeloperation untilfluid level nolonger
decreases.
3. Start engine.
Repeat step2.above.
• Incomplete airbleeding willcause thefollowing tooccur.
When thishappens, bleedairagain.
a. Air bubbles inreservoir tank
b. Clicking noiseinoil pump
c. Excessive buzzinginoil pump
Fluid noise mayoccur inthe valve oroil pump. Thisiscommon
when thevehicle isstationary orwhile turning thesteering
wheel slowly. Thisdoes notaffect theperformance ordurabil-
ity ofthe system.

Checking SteeringWheelTurning Force(For
power steering)

1. Park vehicle onalevel, drysurface andsetparking brake.
2. Start engine.
3. Bring power steering fluiduptoadequate operating temper-
ature. [Make suretemperature offluid isapproximately 60
to 80°C (140to176°F).]

Tires needtobe inflated tonormal pressure.

4. Check steering wheelturning forcewhen steering wheel
has been turned 360°from theneutral position.

Steering wheelturning force: •
39 N(4 kg, 9Ib) orless

5.
If
steering wheelturning forceisout ofspecification, check
rack sliding force.
a. Disconnect steeringcolumnlowerjointandknuckle arms
from thegear.
b. Start andrunengine atidle tomake suresteering fluidhas
reached normaloperating temperature.
c. Pull tie-rod slowlytomove itfrom neutral position to
::l::
11.5
mm
(::l::
0.453 in)atspeed of3.5 mm (0.138 in)/s.Check that
rack sliding forceiswithin specification.

Average racksliding force:
152.0 -240.3 N(15.5 -24.5 kg,34.2 -54.0 Ib)
Maximum forcedeviation:
98 N(10 kg, 22Ib)

6.
If
rack sliding forceisnot within specification, overhaul
steering gearassembly.
7. Ifrack sliding forceisOK, inspect steering column.Referto
ST-13.

Checking Hydraulic System

Before starting, checkbelttension, drivingpulleyandtirepres-
sure. 1. Set Tool. Open shut-off valve.Thenbleed air.(See "Bleed-
ing Hydraulic System"ST-7.)
2. Run engine.

Make suretemperature offluid intank rises to60 to80°C (140
to 176°F).
WARNING:
Warm upengine withshut-off valvefullyopened. Ifengine is
started withshut-off valveclosed, fluidpressure inoil pump
increases tomaximum. Thiswillraise oiltemperature abnor-
mally.

3. Check pressure withsteering wheelfullyturned toleft and
right positions withengine idlingat1,000 rpm.

CAUTION:
Do not hold thesteering wheelinalocked position formore
than 15seconds.
Oil pump maximum standardpressure:
7,649 -8,238 kPa(76.5 .82.4 bar,
78 -84 kg/cm
2,
1,109-1,194 psi)

4.
If
oil pressure isbelow thestandard pressure, slowlyclose
shut-off valveandcheck pressure.
• When pressure reachesstandard pressure, gearisdam-
aged.
• When pressure remainsbelowstandard pressure, pumpis
damaged.

CAUTION: Do not close shut-off valveformore than15seconds.

5.
If
oil pressure ishigher thanstandard pressure, checkoil
pump flowcontrol valve.
6. After checking hydraulic system,removeToolandaddfluid
as necessary. Thencompletely bleedairout ofsystem.
