PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000BB
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 harnesses or
harness connectors.
Precautions for Brake SystemBFS000BC

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 or DOT 4”. Refer to MA-14, "Fluids and Lubricants" .

Do not 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 surfaces of body, immediately wipe it off and them wash it away with water immediately.

To clean or wash all parts of master cylinder, disc brake caliper, use clean 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 torque wrench when installing brake tube.

When installing brake tube, be sure to check torque.

Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery cables.

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-32, "
BRAKE BURNISHING PROCE-
DURE" (Front disc brake), BR-39, "BRAKE BURNISHING
PROCEDURE" (Rear disc brake).
WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

2. Holding down piston with stopper cap, push stopper cap tabs so
they are firmly into cylinder grooves, then install stopper cap.
CAUTION:
Do not reuse stopper cap.
Disassembly (Reservoir Tank)
1. Secure master cylinder assembly into a vise with the chamfered
pin insert hole on cylinder body facing upward.
CAUTION:

When setting master cylinder assembly with vise, be sure
not to over-tighten.

When setting with vise use copper plates or cloth to pro-
tect the flange.
2. Using a pin punch [commercial service tool: diameter approxi-
mately 4 mm (0.16 in)], remove mounting pins on reservoir tank.
3. Remove master cylinder assembly from vise.
4. Remove reservoir tank and grommet from cylinder body.
Assembly (Reservoir Tank)
1. Apply brake fluid to grommet, and then install it into cylinder body after installing grommet to reservoir
tank.
CAUTION:
Do not reuse reservoir tank and grommet.
2. Secure master cylinder assembly into vise with the chamfered
pin insert hole on cylinder body facing upward.
CAUTION:

When setting master cylinder assembly in vise, be sure
not to over-tighten.

When setting in vise use copper plates or cloth to protect
the flange.
