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.

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 piston assembly. Then insert secondary piston
assembly and primary piston assembly into the cylinder body in
this order.
CAUTION:

Do not reuse primary and secondary piston assemblies.

Always replace primary and secondary piston assemblies
as kit.

Pay attention to orientation of the piston cup. Insert it
straight in order to prevent the cups from catching between
the cylinder's inner wall and piston.
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 cylinder body flange with chamfered pin insert hole
facing upward.

When securing in the vise, use copper plates or cloth to
protect the flange.
6. Install reservoir tank to cylinder body. Tilt reservoir tank as
shown in the figure to the extent that the mounting pin can be
inserted and insert mounting pin. When mounting pin passes
through pinhole in master cylinder, return reservoir tank to the
upright position. Push mounting pin all the way through the
opposite pinhole in the reservoir tank.

CAUTION:
Remove reservoir tank only when absolutely necessary.
Disassembly (Piston Assembly)
1. Using a flat-bladed screwdriver as shown in the figure, lift up the
tabs on the stopper cap and remove it from the master cylinder.
NOTE:
Remove stopper cap while holding it because the piston in mas-
ter cylinder may pop out.
2. Carefully pull primary piston assembly straight out to prevent the
cylinder inner wall from being damaged.
3. Tap flange using a soft block, such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder body
inner wall from being damaged.
Inspection After Disassembly (Piston Assembly)
Cylinder body

Check inner wall of cylinder for damage, abrasion, corrosion, and pinholes. Replace the cylinder body if
detected.
Assembly (Piston Assembly)
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply fluid to cylinder inner wall body and contact surface of the
piston assembly. Then insert secondary piston assembly and
primary piston assembly into cylinder body in this order.
CAUTION:

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.

Be sure to replace the assembly without disassembling
the new inner kit.

Do not reuse the primary and secondary piston assem-
blies.

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, "
