BRAKE TUBE AND HOSE
Inspection after Installation
EFS005SO
CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
1. Check hydraulic brake lines (tubes and hoses) and connections for fluid leakage, damage, twists, defor-
mations, contacts with other parts, and loose connections. Replace any damage parts.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running at idle speed for
approximately 5 seconds, check each part for fluid leakage.

OPERATING CHECK
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIRTIGHT CHECK
lRun engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that dis-
tance at intervals of 5 seconds between brake pedal and floor
panel gradually increases.
lDepress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.

CAUTION:
lBecause vacuum hose contains a check valve, it must be
installed in the correct position. Refer to the stamp to con-
firm correct installation. Brake booster will not operate nor-
mally if the hose is installed in the wrong direction.
lInsert vacuum hose at least 24 mm (0.94 in).
lDo not use lubricating oil during assembly.

VISUAL INSPECTION
Check for correct assembly, damage and deterioration.

When connected to the booster side (1):
Vacuum should decrease within 1.3 kPa (10
mmHg, 0.39 inHg) for 15 seconds under a vacuum
of-66.7 kPa (-500 mmHg,-19.69 inHg).
When connected to the engine side (2):

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006DM
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:
lTo 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.
lImproper 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.
lDo 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 SystemEFS005TG
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.If brake fluid is splashed, wipe it off and flush area
with water immediately.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lBrake system is an important safety part.If a brake fluid leak is
detected, always disassemble the affected part.If a malfunction
is detected, replace part with new one.
lBefore working, turn ignition switch OFF and disconnect con-
nector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
lWhen installing brake tube and hose, be sure to torque.
WARNING:
Clean brake pads and shoes with a waster cloth, then wipe with
a dust collector.
Precautions for Brake ControlEFS005TH
lJust after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
lWhen an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.
lIf tyre size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
lIf there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
lIf aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
