WARNING:
Clean dust on caliper and brake pads with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:

While removing cylinder body, do never depress brake pedal because piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Keep rotor clean from brake fluid.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft
pedal occurs at very low mileage. Refer to BR-39, "

INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check inside surface of cylinder for score, rust wear, damage or foreign materials. If any of the above con-
ditions are observed, replace cylinder body.

Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine emery
paper. Replace cylinder body if necessary.
To r q u e M e m b e r
Check for wear, cracks, and damage. If damage or deformation is present, replace torque member.

are stuck to sliding surface.

Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the
above condition are observed.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000CK
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 SystemBFS000CL

Recommended fluid is brake fluid “DOT 3” or “DOT 4”. Refer to MA-14, "RECOMMENDED FLUIDS AND
LUBRICANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

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

Using a flare nut wrench when removing flare nuts, and use a
flare nut torque wrench when tighten brake tube flare nuts.

When installing brake tubes, be sure to check torque.

Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlBFS000CM

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 room. This is a normal condition 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 brake booster operation, brake fluid
level, and fluid leaks.

If tire 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.

TROUBLE DIAGNOSIS

For Fast and Accurate DiagnosisBFS000D3
PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always erase memory after completing trouble diagnosis. Refer to BRC-17, "ERASE MEMORY" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse for connector terminals. Repair or replace applicable part if any non-standard condition
is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table below may occur, but the system is operating normally.
Basic InspectionBFS000D4
BRAKE FLUID LEVEL, LEAKAGE AND BRAKE PAD
1. Check fluid level in the brake fluid reservoir tank. Refill the brake fluid if fluid level is low.
2. Check the area around the brake piping and ABS actuator and electric unit (control unit) for leakage. If
leakage or oozing is detected, check as follows:

If ABS actuator and electric unit (control unit) connections are loose, tighten the flare nut of the piping to
the specified torque. Check again for leakage, and make sure that there is no fluid leakage.

If the flare nuts at the connections and the threads of the actuator are damaged, replace the damaged
parts. Then check again for leakage, and make sure that there is no fluid leakage.

If leakage or oozing is detected on the parts other than actuator connections, wipe with a clean cloth
and check again. If there is still leakage or oozing, replace the damaged part.

If leakage or oozing is detected on actuator body, wipe with a clean cloth and check again. If there is
still leakage or oozing, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad for wear. Refer to BR-26, "
PAD WEAR INSPECTION" in “FRONT DISC BRAKE”, BR-
33, "PAD WEAR INSPECTION" in “REAR DISC BRAKE”.
POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery for looseness on the battery positive/negative terminals and ground connection. Also make sure
that battery voltage does not drop.
Symptom Symptom description Result
Motor operation soundThis is the operation noise of the motor in the actuator, and there may be a slight sound
during ABS operation.
Normal
Just after the engine starts, the motor operating sound may be heard. This is a normal
status of the system operation check.
System operation check
soundWhen engine starts, “click” sound may be heard from engine room. This is normal condi-
tion of system operation check.Normal
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads or gravel
roads, the stopping distance is sometimes longer for vehicles equipped with ABS.
Therefore, when driving on such roads, drive at a sufficiently reduced speed to be safe.Normal
