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

While removing cylinder body, 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 a 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-30, "
Brake Burnishing Procedure" .

der body.
CAUTION:
Be careful not to damage cylinder inner wall.
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 conditions 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 the torque member.
Piston
CAUTION:

Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials
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.
Sliding Pin Bolts and Sliding Pin Boots
Check sliding pin bolts and sliding pin boots, for wear, damage and cracks. If damage or deformation is
present, replace the applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boots. Cover the piston end with piston boot, and install cylinder side lip on piston boots properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000MW
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 SystemNFS000MX

Recommended fluid is brake fluid “DOT 3”. Refer to MA-12, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Do not 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.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut crowfoot and 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 electri-
cal connectors of ABS actuator and electric unit (control unit) or
battery negative terminal.

When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlNFS000MY

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

Just after starting vehicle after turning 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.

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
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.
