On-Vehicle Inspection and AdjustmentEFS000C1
Adjust clearance between dash panel and brake pedal upper surface
to the following dimensions.
1. Loosen stop lamp switch by rotating it counter-clockwise by 45°.
2. Loosen input rod lock nut (A), then rotate input rod, set pedal to
the specified height, and tighten lock nut (A).
CAUTION:
Confirm threaded end of input rod remains inside the cle-
vis.
3. Pull pedal by hand and hold it. Press stop lamp switch until its
threaded end contacts the stopper rubber.
4. While holding it against the stopper rubber, turn the switch clock-
wise by 45° and secure it.
CAUTION:
Be sure stopper rubber to stop lamp switch screw threaded
end gap (C) is within the specifications.
5. Check pedal free play.
CAUTION:
Be sure stop lamps go off when pedal is released.
6. Start engine and check brake pedal depressed height.

BRAKE BOOSTERPFP:47200
On-Vehicle Inspection and ServiceEFS000CC
FUNCTION INSPECTION
With engine stopped, discharge stored vacuum by depressing brake
pedal several times at 5 second intervals. With brake pedal fully
depressed, start the engine. Confirm that clearance between brake
pedal and floor panel decreases when engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION

Run engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress brake pedal several
times with normal force to discharge the stored vacuum. Con-
firm that clearance between brake pedal and floor panel gradu-
ally increases as the brake pedal is depressed.

Run engine. Depress and hold brake pedal then stop engine.
Keep brake pedal depressed for 30 seconds or more and make
sure the pedal stroke does not change.
Removal and InstallationEFS000CD
REMOVAL
CAUTION:

Be careful not to deform or bend brake piping while remov-
ing and installing brake booster.

Replace clevis pin if it is damaged.

Be careful not to damage brake booster stud bolt threads. If
brake booster is tilted or inclined during installation, dash
panel may damage the threads.

Be sure to install check valve in the correct orientation.
1. Remove vacuum piping from the brake booster.
2. Remove master cylinder.
3. Remove snap pin and clevis pin on the clevis of input rod. Remove input rod from the brake pedal.
4. Remove brake booster and brake pedal assembly mounting nuts.
5. Remove booster assembly from the engine compartment.

PRECAUTIONS

[ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS004GW
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 SystemEFS004GX

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 body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Never use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut torque wrench, securely tighten brake tube
flare nuts.

Brake 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 a new one.

Before working, turn ignition switch OFF and disconnect har-
ness connectors of ABS actuator and electric unit (control unit)
or battery negative terminal.

When installing brake piping, be sure to check torque.
Precautions for Brake ControlEFS004FV

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When 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 booster operation, brake fluid level, and
oil leaks.

If 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.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
