• Refill using recommended brake fluid. Refer to MA-14 .
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted surfac e of body. If brake fluid is splashed on painted surfaces
of body immediately wipe it off with cloth and then wash it away with water.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use a flare nut wrench when removing a brake tube and use a flare nut torque wrench when installing a brake tube.
• When installing brake tubes and hoses, be sure to check torque.
• Before working, turn igniti on switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
• Burnish the new braking surfaces after refinishing or replacing drums or rotors, after replacing p ads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-32, " Brake Burnishing
Procedure " .

5. Remove piston seal with a flat-bladed screwdriver. CAUTION:
Be careful not to damage the inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, w ear, and damage. Replace cylinder body as necessary.
CAUTION:
Clean cylinder body using new brake fluid. Never use mineral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. R eplace torque member as necessary.
Piston
Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated . Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. Replace applicable
part as necessary.
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cr acks, and serious damage. Replace as necessary.

2. Using a dial indicator, check runout.
CAUTION:
Make sure that wheel bearing axi al end play is within the
specifications before measuring runout. Refer to FAX-6," On-Vehicle Inspection and Service " .
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by
one hole.
4. If runout is still out of the specific ation, grind rotor on-car using Tool until runout is within the specified limit.
Thickness Inspection Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specifications, replace disc rotor.

Brake Burnishing Procedure INFOID:0000000004305914
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicl e within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

Precaution for Supplemental Restraint Syst em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004784402
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether 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 inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution for Brake System INFOID:0000000004307251
CAUTION:
• Refer to MA-14 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 cylin der 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 sys-
tem.
• Use flare nut wrench when re moving 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 an d remove the connector of the
ABS actuator and electric unit (c ontrol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to BR-32, " Brake Burnishing Proce-
dure " .
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe with a dust collector. SBR686C

2. Without disassembling the hydraulic lines, remove the torque member bolts using power tool. Then repo-
sition the torque member and brake caliper assembly aside with wire. Refer to BR-25 .
CAUTION:
Do not depress brake pedal while brake caliper is removed.
3. Put alignment marks on disc rotor and wheel hub and bearing assembly, then remove disc rotor.
4. Remove wheel sensor from steering knuckle. Refer to BRC-32 .
CAUTION:
Do not pull on wheel sensor harness.
5. Loosen steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so as not to damage ball joint (3) boot using Tool.
CAUTION:
Temporarily leave the outer so cket nut installed to prevent
damage to threads and to pr event the ball joint remover or
suitable tool from suddenly coming off.
7. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
8. Remove cotter pin, then loosen hub lock nut using power tool. CAUTION:
Temporarily leave the hub lock nut inst alled to prevent damage to threads.
9. Separate the drive shaft from the wheel hub and bearing assem- bly by lightly tapping the end of the drive shaft using a hammer
or suitable tool, and then remove hub lock nut.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and
drive shaft cannot be separated after performing the above pro-
cedure.
10. Remove the drive shaft from the wheel hub and bearing assem- bly and support the drive shaft.
CAUTION:
• Do not apply an excessive angle to drive shaft joint when
removing from the wheel hub and bearing assembly,
• Do not excessively extend slide joint.
• Do not allow drive shaft to hang do wn. Support the entire drive shaft.
11. Remove wheel hub and bearing assembly bolts, and then remove splash guard and wheel hub and bear- ing assembly from steering knuckle.
