5. While pushing primary piston, remove piston stopper through
secondary tank boss hole in the cylinder body.
6. Remove snap ring with pushing primary piston.
CAUTION:
Be careful not to pop out piston.
7. Holding rod of primary piston, remove primary piston assembly,
plate and guide assembly by pulling straight to prevent piston
cup from being caught by the inner wall of cylinder.
8. Remove plate and guide assembly from primary piston.
CAUTION:
Be careful not to damage rod from the inner wall of plate.
9. Tap flange using a soft block such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder inner
wall from being damaged.
INSPECTION AFTER DISASSEMBLY
Cylinder Body

Check the inner wall of cylinder for damage, wear, corrosion, and pin holes. Replace cylinder body if nec-
essary.
ASSEMBLY
CAUTION:

Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.

Make sure that there is no foreign material such as dirt and dust on the inner wall of cylinder, pis-
ton, and piston cup. Be careful not to damage parts with a service tool when assembling.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to the inner wall of cylinder body, primary pis-
ton assembly and secondary piston assembly.
2. Insert secondary piston and primary piston assembly into cylin-
der body in this order.
CAUTION:

Pay attention to the orientation of piston cup, and insert
straight to prevent cup from being caught by the inner
wall of cylinder.

Always replace inner kit as a set.

CAUTION:

Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed
air.

While removing brake pad or cylinder body, do not depress brake pedal because piston will pop
out.

It is not necessary to remove torque member mounting bolts and brake hose except for disassem-
bly or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake
hose is not under tension.

Do not damage piston boot.

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

Keep rotor free from brake fluid.

When replacing brake pad, replace shim with a new one.
Removal and Installation of Brake PadEFS006JP
REMOVAL
1. Remove tires from vehicle.
2. Remove sliding pin bolt (lower side).
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.
INSTALLATION
1. Apply AS-880N grease or equivalent to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.
CAUTION:

When installing pad retainer, attach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.
CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-24, "
Compo-
nents" .

PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006L7
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.
WAR NIN G:

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 EFS006L8
CAUTION:

Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.

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.

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.

Use flare nut wrench when removing and installing brake
tube.

If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.

Turn the ignition switch OFF and remove the connector of
the ABS actuator and electric unit (control unit) or the bat-
tery terminal before performing the work.

Always torque brake lines when installing.

Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage. Refer to BR-29, "
Brake Burnishing Procedure" .
WAR NIN G:

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions When Using CONSULT-IIEFS006L9
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?

If YES, GO TO 2.

If NO, GO TO 5.
