REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
EES0007F
Check axle and suspension parts for excessive play, wear, and damage.
●Move rear wheels (RH/LH) to check abnormal free play.
●Retighten all nuts and bolts to the specified torque.
●Check strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION
●Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.
●If the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.
●Always perform following procedure on a flat surface.
●Make sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear 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 tires at the
same height as hub center. This mark is a measuring points.

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 harness connec-
tors.
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 paint, 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.
●The brake system is an important safety part. If a brake fluid
leak is detected, always disassemble the related parts. If dam-
age, deformation or excessive wear is detected, replace
affected parts with new ones.
●Before staring 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 FLUIDPFP:KN100
Checking Brake Fluid Level EFS000C5
●Confirm reservoir tank fluid level is within 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 spill or splash 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 the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel
while depressing the brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

ASSEMBLY
CAUTION:
●Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.
●Be sure there is no foreign material on the cylinder inner wall, piston, and cup seal. Be careful not
to damage parts with a service tool during assembly.
●Do not drop the parts. Do not use any dropped parts.
1. Apply brake fluid to the inner wall of cylinder body and contact
surface of the piston assembly. Then insert secondary piston
assembly and primary piston assembly into cylinder body in this
order.
CAUTION:
●Do not reuse primary and secondary piston assemblies.
●Always replace the inner kit as an assembly.
●Pay attention to orientation of the piston cup. Insert it
straight in order to prevent it from catching on the cylin-
der's inner wall.
2. Visually check secondary piston slit position through cylinder
body secondary tank boss hole and install piston stopper.
3. Hold piston with stopper cap. Press stopper cap in until its tabs
fully engage groove on the cylinder body.
CAUTION:
Do not reuse stopper cap.
4. Apply brake fluid to grommet before pressing it into cylinder
body.
CAUTION:
Do not reuse grommet.
5. Secure cylinder body flange in a vise as shown in the figure.
CAUTION:
●Secure with chamfered pin insert hole on the cylinder body
facing upward.
● When securing in the vise, use copper plates or cloth to
protect the flange.
6. Install reservoir tank to the cylinder body. Tilt reservoir tank as
shown in the figure and insert mounting pin. When mounting pin
passes through pinhole in the master cylinder, return reservoir
tank to the upright position. Push mounting pin all the way
through the opposite pinhole in the reservoir tank.
CAUTION:
●Do not reuse reservoir tank mounting pin.

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 get 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 connecting 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 contact surfaces after refinishing or replacing drums or rotors, after replacing
pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-10, "
Brake Burnishing

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.
