Drain and RefillINFOID:0000000009463692
CAUTION:
• Do not spill or splash brake fluid on painted surf aces. Brake fluid may damage paint. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• Prior to repair, turn the ignition switch OFF, disconnect the ABS actuator and electric unit (control
unit) connector or negative battery terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
• Refill brake system with new brake fluid. Refer to MA-11, "FOR USA AND CANADA : Fluids and
Lubricants".
• Do not reuse drained brake fluid.
DRAINING
1. Turn ignition switch OFF and disconnect ABS actuat or and electric unit (control unit) connector or nega-
tive battery terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
2. Connect a vinyl tube to bleeder valve.
3. Depress brake pedal, loosen bleeder valve, and gradually remove brake fluid.
REFILLING
1. Make sure no foreign material is in the reservoir, and refill withnew brake fluid.
CAUTION:
Do not reuse drained brake fluid.
2. Refill the brake system as follows: • Depress the brake pedal.
• Loosen bleeder valve.
• Slowly depress brake pedal to 2/3 of the brake pedal full
stroke.
• Tighten bleeder valve.
• Release brake pedal.
Repeat this operation at intervals of two or three seconds until
all old brake fluid is discharged. Add new brake flui d to master cylinder reservoir sub tank frequently.
CAUTION:
Do not allow master cylinder reservoir to empt y as this may cause damage to master cylinder
internal components.
3. Bleed the air out of the brake hydraulic system. Refer to BR-14, "Bleeding Brake System"
.
Bleeding Brake SystemINFOID:0000000009463693
BLEEDING BRAKE SYSTEM
CAUTION:
• While bleeding, pay attention to master cylinder fluid level.
• Prior to repair, turn the ignition switch OFF, disconnect the ABS actuator and electric unit (control
unit) connector or negative battery terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
1. Connect a vinyl tube to rear right brake caliper bleeder valve.
2. Fully depress brake pedal ten times.
3. With brake pedal depressed, loosen bleeder valve to bleed air in brake line, and then tighten it immedi-
ately.

CAUTION:
• All hoses and piping (tubes) must be fr ee from excessive bending, twisting and pulling.
• Make sure there is no interference with other pa rts when turning steering both clockwise and coun-

• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the
parts. Replace applicable part with a new one, if necessary.
• 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.
• Do not bend or twist brake hose sharply, or strongly pull it.

INFOID:0000000009951721
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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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 in correct 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 SR 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 three minutes before performing any service.
Precaution for Brake SystemINFOID:0000000009463735
WARNING:
Clean any dust from the front brake and rear br ake using a vacuum dust collector. Do not blow by
compressed air.
• Brake fluid use refer to BR-8, "Inspection"
.
• Do not reuse drained brake fluid.
• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.
• Always confirm the specified tightening torque when installing the brake pipes.
• After pressing the brake pedal more deeply or harder t han normal driving, such as air bleeding, check each
item of brake pedal. Adjust brake pedal if it is outside the standard value.
• Do not use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause
improper operation.
• Always loosen the brake tube flar e nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a crow-
foot (A) and torque wrench (B).
• Always connect the battery terminal when moving the vehicle.
• Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) harness connector or the battery negative
terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the parts.
