DESCRIPTION
This section is prepared for technicians who have attained a high level of skill and experience in repairing col-
lision-damaged vehicles and also use modern servic e tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.
Technicians are also encouraged to read Body Repair M anual (Fundamentals) in order to ensure that the orig-
inal functions and quality of the vehicle can be mainta ined. The Body Repair Manual (Fundamentals) contains
additional information, including cautions and warning, that are not including in this manual. Technicians
should refer to both manuals to ensure proper repairs.
Please note that these information are prepared for wo rldwide usage, and as such, certain procedures might
not apply in some regions or countries.

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612918
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001612920
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000001327604
 Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
 Recommended fluid is brake fluid “DOT 3”. MA-9, "
Fluids and Lubricants".
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut crowfoot and torque wrench when installing brake
tube.
 When installing brake piping, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec- tors for ABS actuator and electric unit (control unit) or battery neg-
ative terminal.
 Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-23, "
Brake Burnishing Procedure" (Front disc brake),
BR-29, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
 Clean brake pads and shoes with a waste cl oth, then clean with a dust collector.

BRAKE FLUID
On-Board InspectionINFOID:0000000001327610
LEVEL CHECK
 Make sure the fluid level in reservoir tank is within the standard(between MAX and MIN lines).
 Visually check around reservoir tank for fluid leakage.
 If fluid level is excessively low, check brake system for leakage.
 Release parking brake pedal and see if brake warning lamp goes off. If not, check brake system for fluid leakage.
Drain and RefillINFOID:0000000001327611
CAUTION:
 Refill with new brake fluid “DOT3”.
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
 Before working, disconnect connectors of ABS actua tor and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bl eed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
5. Bleed Air. Refer to BR-8, "
Bleeding Brake System".

WARNING:
Clean dust on caliper and brake pad with a vacuum du st collector to minimize the hazard of airborne
particles or other materials.
CAUTION:
 While removing cylinder body, never depr ess brake pedal because piston will pop out.
 It is not necessary to remove bolts on torq ue 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-29, "
Brake Burnishing Procedure".
Removal and Installation of Brake PadINFOID:0000000001327635
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 silic one-based grease to the backside of pad and to both sides
of shim, and install inner shim and shim cover to inner pad, and install the outer shim to outer pad.
2. Install pad retainer and mount pad assemblies to torque member.
3. Push piston in so that pad is firmly installed and mount cylinder body to torque member. CAUTION:
When replacing pads with new ones, press in piston until pads can be installed. In this case, care-
fully monitor brake fluid level in reservoir tank because brake fluid will return to master cylinder
reservoir tank.
4. Install sliding pin bolt (one on top) and tighten to the specified torque. Refer to BR-24, "
Component".
5. Check brake for drag.
6. Install tires to the vehicle.
