CALIPER INSPECTION
Cylinder Body
CAUTION:
●
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.
●
Check inside surface of cylinder for score, rust wear, damage or foreign materials. If any of the
above conditions are observed, replace cylinder body.
●
Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston
CAUTION:
●
Piston sliding surface is plated, do not polish with emery paper even if rust or foreign materials
are stuck to sliding surface.
●
Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the
above conditions are observed.
Sliding Pin Bolts and Sliding Pin Boots
Make sure there is no wear, damage, or cracks in sliding sleeve and sliding sleeve boots, and if there are,
replace them.
ASSEMBLY
CAUTION:
Do not use NISSAN Rubber Grease (KRE00 00010, KRE00 00010 01) when assembling.
1.
Apply clean brake fluid to new piston seal and insert into groove
on cylinder body.
CAUTION:
Do not reuse piston seal.
2.
Apply brake fluid to piston and to piston boot, then install piston
boot into piston groove.
CAUTION:
Do not reuse piston boot.
3.
Insert into cylinder body by hand and insert piston boot piston-side lip into piston groove.
CAUTION:
Press piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.
4.
Install sliding boots and sleeves to cylinder body.

DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is
detected, replace applicable part.
Runout Inspection
1.
Using wheel nuts, install disc rotor to wheel hub in 2 or more positions.
2.
Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in)
inside disk edge.]
NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cation before measuring runout. Refer to
3.
If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.
4.
If runout still out of specification, turn rotor with on-car brake
lathe.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is
either at or below the wear limit, or exceeds maximum uneven wear,
replace disc rotor.
Brake Burnishing
EFS006G9
Burnish brake contact surface according to the following procedure after refinishing or replacing rotors, after
replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1.
Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2.
Use medium brake pedal/foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH). Adjust
brake pedal/foot pressure such that vehicle stopping time equals 3 to 5 seconds.
3.
To cool brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4.
Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

PRECAUTIONS

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS0064H
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:
●
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 System
EFS0064I
CAUTION:
●
MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS"
for recommended brake fluid.
●
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 with water immediately.
●
To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
●
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
●
Use flare nut wrench when removing and installing brake
tube.
●
If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
●
Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.
●
Always torque brake lines when installing.
●
Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to
(front disc brake) or
(rear disc
brake).
WARNING:
●
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-II
EFS0064J
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1.
Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
●
If YES, GO TO 2.
