CALIPER INSPECTION
Cylinder Body
CAUTION:

Use new brake fluid for cleaning. 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 affected part.
Piston
Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the above con-
dition are observed.
CAUTION:
Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
Sliding Pins, and Sliding Pin Boots
Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the affected part.
ASSEMBLY
CAUTION:
Do not use NISSAN Rubber Grease (KRE00 00010, KRE00 00010 01) when assembling.
1. Apply rubber grease to new piston seal and insert seal in to
groove on cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply brake fluid to piston, rubber grease to piston boot, then
install piston boot in to piston groove.
CAUTION:
Do not reuse piston boot.
3. Insert into cylinder body by hand and insert piston boot piston-side lip into piston groove.
CAUTION:
Press piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.
4. Install sliding pins and sliding pin boots to torque member.
5. Attach inner shim and inner shim cover to inner pad, and attach the outer shim to the outer pad.
6. Install cylinder body. Tighten sliding pin bolt to the specified torque.

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
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.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer to BR-29, "
BRAKE BURNISHING PROCEDURE"
Removal and Installation of Brake PadAFS001NC
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove sliding pin bolt (one on top).
3. Suspend cylinder body with a wire, and remove pads, pad retainers, shim from torque member.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicon- based grease to the backside of pad and to both sides
of shim, and attach inner shim and shim cover to inner pad, and attach the outer shim and outer shim
cover to outer pad.
2. Install pad retainer and mount pad to torque member.
3. Push piston in so that pad is firmly attached and mount cylinder body to torque member.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in piston.
CAUTION:
By pushing in piston, brake fluid returns to master cylinder reservoir tank. Watch the level of the
surface of reservoir tank.
4. Install sliding pin bolt (one on top) and tighten to the specified torque.
5. Check brake for drag.
6. Install tires to the vehicle.
Removal and Installation of Brake Caliper AssemblyAFS001ND
REMOVAL
1. Remove tires from vehicle with power tool.
2. Drain brake fluid. Refer to BR-9, "
Drain and Refill" .
3. Remove union bolt and torque member bolts, and remove brake
caliper assembly from the vehicle.
4. Remove disc rotor.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3”.

Do not reuse drained brake fluid.
1. Install disc rotor.
2. Install caliper assembly to the vehicle, and tighten bolts to the specified torque.

CAUTION:
Before installing caliper assembly to the vehicle, wipe off oil and grease on washer seats on axle
assembly and mounting surface of caliper assembly.
3. Install brake hose to caliper assembly and tighten union bolt to the specified torque.
CAUTION:

Do not reuse copper washer for union bolt.

Securely attach brake hose to protrusion on caliper assembly.
4. Refill new brake fluid and bleed air. Refer to BR-10, "
Bleeding Brake System" .
5. Install tires to the vehicle.
Disassembly and Assembly of Brake Caliper AssemblyAFS001NE
DISASSEMBLY
1. Remove sliding pin bolt, and then remove pad, shim, shim cover, and pad retainer from torque member
and cylinder.
2. Remove sliding pin boot from torque member.
3. As shown in the figure, using a flat-bladed screwdriver, remove
retaining ring from cylinder body.
4. Place a wooden block as shown in the figure, and blow air from
union bolt mounting hole to remove pistons and piston boots.
CAUTION:
Do not get your fingers caught in piston.
5. Using a flat-bladed screwdriver, remove piston seals from cylin-
der body.
CAUTION:
Be careful not to damage cylinder inner wall.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45

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

If the following components are replaced with non-genuine components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tires, wheels (exclude specified size),
components related to brake (Pad, Rotor, Caliper, etc.), components related to engine (Muffler, ECM,
etc.), components related to body reinforcement (Roll bar, Tower bar, etc.).

Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may
not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or VDC OFF indicator lamp and SLIP
indicator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after
restarting engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC SW
ON) may cause the G -sensor system indicate a malfunction. However, this is not a malfunction, if normal
operation can be resumed after restarting engine.
