To e - i n
Measure toe-in using the following procedure.
WARNING:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tyre at the
same height as hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180degrees
(1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance “B” (front side).
STEERING ANGLE INSPECTION
1. Set wheels in straight-ahead position. Move vehicle to set front wheels on turning radius gauge.
2. Turn steering wheel fully to right and left, and measure steering angle. Refer to PS-44, "

Removal and InstallationEES00074
REMOVAL
1. Remove tyre. Remove brake caliper and hung it aside.
CAUTION:
Avoid depressing brake pedal with brake caliper removed.
2. Remove electrical wires of wheel sensor from strut.
3. Remove brake hose lock plate.
4. Remove mounting bolts and nuts securing steering knuckle to strut.
5. Remove mounting nuts on upper mounting plate and remove upper mounting plate and strut from vehicle.
INSTALLATION

Refer to FSU-5, "Components" in “Front Suspension Assembly” for tightening torque. Tighten in the
reverse order of removal.

Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in strut spacer is
positioned as shown. Then install strut.

Assemble upper mounting plate with its notch facing toward the
outside.
Disassembly and AssemblyEES00075
DISASSEMBLY
1. Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing strut attachment (SST), wrap a shop cloth
around strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately so as not to tilt the spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.

Remove strut spacer, strut mount insulator, strut mounting insulator bracket thrust bearing, spring upper
seat, and upper rubber seat. Then remove coil spring.
6. Remove bound bumper from spring upper seat.
7. Gradually release spring compressor (commercial service tool), and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut

Check strut for deformation, cracks, and damage, and replace if necessary.

Check piston rod for damage, uneven wear, and distortion, and replace if necessary.

Check welded and sealed areas for oil leakage, and replace if necessary.

3. Install small parts to the strut.

Connect upper rubber seat, spring upper seats, thrust bearing, strut mount insulator, and strut spacer.
Temporarily install piston rod lock nut.
CAUTION:
Do not reuse piston rod lock nut.
4. Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in the strut spacer
is positioned as shown.
5. Be sure coil spring is properly set in spring rubber seat. Gradu-
ally release spring compressor.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS002F9
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:

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 for Brake SystemEFS000BZ

Clean dust on brake pads, shoes, drums, and back plates with a vacuum dust collector. Do not blow with
compressed air.

Recommended fluid is brake fluid “DOT 3” or “DOT 4”.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as the body. If brake fluid is splashed or spilled
on painted areas, wipe it off and flush the area with water immediately.

Use only clean brake fluid when cleaning master cylinder and disc brake components.

Never use mineral oils such as gasoline or kerosene to clean. They will ruin the rubber parts and cause
improper operation.

Always use a flare nut torque wrench to securely tighten brake
tube flare nuts.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the related parts. If damage,
deformation or excessive wear is detected, replace affected
parts with new ones.

Before starting operation, be sure to turn the ignition switch OFF
and disconnect the ABS actuator and control module connector
or battery cables.

When installing brake piping, be sure to check torque.SBR820BA

BRAKE FLUID

BRAKE FLUIDPFP:KN100
Checking Brake Fluid Level EFS000C5

Confirm reservoir tank fluid level is within the specifications
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Always keep fluid level higher than minimum line on reservoir tank.

Never reuse drained brake fluid.

Be 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 water immediately.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while
depressing brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

ComponentEFS000CG
WARNING:

Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:

When cylinder body is open, do not depress brake pedal because piston will pop out.

Be careful not to damage piston boot or spill brake fluid oil on rotor. Always replace shims when
replacing pads.

If shims are rusted or show peeling of the rubber coat, replace them with new shims.

It is not necessary to remove torque member mounting bolt and brake hose union bolt except for
disassembly or replacement of caliper assembly. In this case, suspend cylinder body with wire so
as not to stretch brake hose.

Burnish the brake pad contact surfaces after refinishing or replacing drums or rotors, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-31, "
BRAKE BUR-
NISHING PROCEDURE" .

DISASSEMBLY
WARNING:
Be careful not to pinch your fingers in the piston.
CAUTION:
Be careful not to damage the cylinder inner wall.
1. Place a wooden block as shown in the figure. Blow air into union
bolt mounting hole to remove pistons and piston boots.
2. Using flat-bladed screwdriver, remove piston seals.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.

Check cylinder inner wall for corrosion, wear and damage. If corrosion, wear or damage is detected,
replace the cylinder body.

Minor flaws caused by corrosion or foreign material can be removed by polishing the surface with fine
sandpaper. Replace the cylinder body, if necessary.
To r q u e M e m b e r
Check for wear, cracks and damage. If wear, cracks or damage is detected, replace the applicable part.
