FRONT DISC BRAKE
CAUTION:
• Never depress the brake pedal while removing the brake pads or the cylinder body because the pis-
ton may pop out.
• Never spill or splash brake fluid on the disc rotor.
1.
Install the pad retainer to the torque member if the pad retainers has been removed.
CAUTION:
• Never reuse the pad retainers.
• Securely assemble the pad retainers so that it will not be lifted up from the torque member.
• Never deform the pad retainers.
2.
Apply MOLYKOTE
®
7439 or equivalent to the mating faces between the brake pads and pad retainers.
Molykote is a registered trademark of Dow Corning Corporation.
3.
Apply MOLYKOTE
®
AS880N or silicone-based grease to the mating faces between the shims and shim
covers, and install them to the brake pad.
CAUTION:
Always replace the shims together with the shim covers when replacing the brake pad.
Molykote is a registered trademark of Dow Corning Corporation.
4.

pad retainer. Install pad return lever (1) securely to pad wear
sensor (2).
5.
Install the cylinder body to the torque member.
CAUTION:
• Never damage the pistons boots.
• When replacing brake pad with new one, check a brake
fluid level in the sub tank because brake fluid returns to
master cylinder of sub tank when pressing piston in.
NOTE:
Use a disc brake piston tool to easily press pistons.
6.
Install the lower sliding pin bolt and tighten it to the specified torque.
7.
Depress the brake pedal several times to check that no drag feel is present for the front disc brake. Refer
to
BR-34, "BRAKE PAD : Inspection"
.
8.
Install tires with power tool. Refer to
WT-44, "Removal and Installation"
BRAKE PAD : Inspection
INFOID:0000000007567033
INSPECTION AFTER REMOVAL
Replace the shims and the shim covers if rust is excessively attached.
INSPECTION AFTER INSTALLATION
1.
Check a drag of front disc brake. If any drag is found, follow the procedure described below.
2.
Remove brake pads.
3.
Press the pistons.
CAUTION:
• Never damage the pistons boots.
• When replacing a pad with new one, check a brake fluid level in the reservoir tank because brake
fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool to easily press pistons.
4.
Install brake pads.
5.
Depress the brake pedal several times.
6.
Check a drag of front disc brake again. If any drag is found, disassemble the cylinder body. Refer to
36, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"
.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007808972
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 AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Service Procedure Precautions for Models with a Pop-up Roll Bar
INFOID:0000000007808973
WARNING:
Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll
over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.
• Before removing and installing the pop-up roll bar component parts and harness, always turn the
ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)
• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS
AIR BAG CONTROL warnings in the Service Manual.
Precaution for Battery Service
INFOID:0000000007808974
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
