REMOVAL

CAUTION:

●

Before servicing, disconnect battery terminals.

●

To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use a flare nut torque wrench and tighten to the specified torque.

INSTALLATION

Be careful of the following.

●

Tighten mounting bolts and nuts to the specified torque.

●

After the work, bleed the brakes. Refer to

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

EFS002WL

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 System

EFS002WM

●

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; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.

●

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of hydraulic system.

●

Use flare nut wrench when removing and installing brake tubes.

●

Always torque brake lines when installing.

●

Before working, turn the ignition switch OFF and disconnect the
connectors for the ESP/TCS/ABS actuator and control unit or
the battery terminals.

●

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer to

BR-27, "BRAKE BURNISH-

ING PROCEDURE"

WARNING:

Clean brakes with a vacuum dust collector to minimize risk
of health hazard from powder caused by friction.

Precautions for Brake Control

EFS002WN

●

During the ESP/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be
heard. This is a normal condition.

●

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

●

The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough,
gravel, or snowy (fresh deep snow) road.

●

If a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary infor-
mation from the customer (what symptoms are present under what conditions) and find out the possible
causes before starting the service. Besides the electrical system inspection, check the booster operation,
brake fluid level, and oil leaks.

●

If the tire size and type are used in a improper combination, or the brake pads are not NISSAN genuine
parts, the stopping distance or steering stability may deteriorate.

●

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

●

If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check the electrical har-
nesses for pinches, open, and improper wiring.

FOR INSPECTION

●

Do not apply voltage of 7.0V or higher to the measurement terminals.

●

Use the tester with its open terminal voltage being 7.0V or less.

●

Before harness inspection, turn the ignition switch off, disconnect the negative battery terminal.

FOR HARNESS REPAIR

●

Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in)]

●

Do not perform bypass wire connections for the repair
parts.(The spliced wire will become separated and the charac-
teristics of twisted line will be lost.)
