Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS002F9
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 harness connec-
tors.
Precautions for Brake SystemEFS000BZ
●Clean dust on brake pads, shoes, drums, and back plates with a vacuum dust collector. Do not blow with
compressed air.
●Recommended fluid is brake fluid “DOT 3” or “DOT 4”.
●Never reuse drained brake fluid.
●Be careful not to splash brake fluid on painted areas such as the body. If brake fluid is splashed or spilled
on paint, wipe it off and flush the area with water immediately.
●Use only clean brake fluid when cleaning master cylinder and disc brake components.
●Never use mineral oils such as gasoline or kerosene to clean. They will ruin the rubber parts and cause
improper operation.
●Always use a flare nut torque wrench to securely tighten brake
tube flare nuts.
●The brake system is an important safety part. If a brake fluid
leak is detected, always disassemble the related parts. If dam-
age, deformation or excessive wear is detected, replace
affected parts with new ones.
●Before staring operation, be sure to turn the ignition switch OFF
and disconnect the ABS actuator and control module connector
or battery cables.
●When installing brake piping, be sure to check torque.SBR820BA

BRAKE FLUID
4. Be sure there is no foreign material in reservoir tank. Refill with
new brake fluid.
5. Connect a vinyl tube to the air bleeder.
6. Rest foot on brake pedal. Loosen air bleeder. Slowly depress
pedal until it stops. Tighten air bleeder. 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.
For bleeding procedure. Refer to BR-10, "
Bleeding Brake Sys-
tem" .
Brake Burnishing ProcedureEFS001C8
Burnish the brake contact surfaces according to the following procedure after refinishing or replacing drums or
rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal/foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH). Adjust
brake pedal/foot pressure such that vehicle stopping time equals 3 to 5 seconds.
3. To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.
Bleeding Brake SystemEFS000C4
CAUTION:
●Carefully monitor brake fluid level at master cylinder during bleeding operation.
●Fill reservoir with new brake fluid “DOT 3” or “DOT 4”. Make sure it is full at all times while bleed-
ing air out of system.
●Place a container under master cylinder to avoid spillage of brake fluid.
●While bleeding, pay attention to master cylinder fluid level.
●For models with ABS, turn ignition switch OFF and disconnect ABS actuator connectors or bat-
tery ground cable.
●Bleed air in the following order.
Right rear brake, Left front brake, Left rear brake, Right front brake
1. Turn OFF ignition switch. Remove ABS actuator connector.
2. Connect a vinyl tube to the air bleeder.
3. Fully depress the brake pedal 4 to 5 times.
4. With brake pedal depressed, loosen air bleeder and bleed air.
5. Close air bleeder.
6. Slowly release brake pedal.
7. Tighten air bleeder to the specified torque.
8. Repeat steps 2 - 7. Occasionally refill master cylinder reservoir tank. Be sure to keep it at least half-full.

WARNING:
●Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:
●When cylinder body is open, do not depress brake pedal because piston will pop out.
●Be careful not to damage piston boot or get oil on rotor. Always replace shims when replacing
pads.
●If shims are rusted or show peeling of the rubber coat, replace them with new shims.
●It is not necessary to remove connecting bolt except for disassembly or replacement of caliper
assembly. In this case, suspend cylinder body with wire so as not to stretch brake hose.
●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-10, "
Brake Burnishing

REMOVAL
CAUTION:
When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.
1. Remove master cylinder reservoir tank cap.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
