REMOVAL
CAUTION:
●Do not allow brake fluid to spill or splash on painted surfaces. Brake fluid can seriously damage
paint. If it gets on a painted surface, wipe it off immediately and wash with water.
●Do not bend or twist the brake hose sharply, or strongly pull it.
●Cover brake fluid line connections to prevent dust and other foreign material from entering.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel while depressing the brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from the brake hose.
4. Remove union bolts and disconnect caliper assembly from the
brake hose.
5. First remove lock spring from brake tube and strut mounting
positions. Then remove brake hose.
INSTALLATION
CAUTION:
●Refill with new brake fluid “DOT 3” or “DOT4”.
●Never reuse drained brake fluid.
1. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.
CAUTION:
●Securely connect brake hose to the protrusions on the cylinder body.
●Do not reuse the copper washer for union bolts.
2. Connect brake hose to the strut and fix with lock spring.
3. Connect brake hose to brake tube. Temporarily tighten flare nuts by hand as far as they will go. Secure
them with the lock spring.
4. Using a flare nut torque wrench, tighten to the specified torque.

PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS000IZ
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.
CautionEGS00049
●Always follow the warnings and the cautions below in disassembly procedures:
–Work in a clean, dust-free place. No dust proof device is necessary.
–Clean outside of unit before disassembly.
–Clean parts to be disassembled. Be careful not to allow any dirt or other foreign materials to enter or con-
tact with parts.
–Assemble disassembled parts properly, following order shown in manual. If work has been suspended in
the middle of assembly, place a clean cover over parts. This will prevent them from being contaminated.
–Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on
cleaned parts that might affect operation of parts.
–Clean disassembled parts (except rubber parts) with kerosene. Drain oil by blowing with air or absorbing
with shop papers.
–Before assembling, apply Nissan power steering fluid to O-rings and seals.
–Replace gaskets and O-rings with new ones. Be careful not to damage any O-rings, oil seals, and gaskets
during assembly.
●If following part is scratched after disassembly of steering pump, replace applicable part: case, rear body,
side plate, pulley, rotor, vane, or flow control valve
●Mark source of fluid leak with a white marker for identification.
● Seals and copper washers must not be reused.

POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS0004B
●Check the fluid level with the engine OFF.
●Check that fluid level is between MAX and MIN marks on tank.
Fluid level should not exceed MAX mark. Excessive fluid will
cause fluid to leak from cap.
●Note that fluid level can change depending on temperature of
fluid. HIGH and LOW marks are shown on tank to indicate the
proper level at high temperature and low temperature respec-
tively.
CAUTION:
●Never reuse drained power steering fluid.
●Use DEXRONTM III or equivalent. Never use Nissan Power Steering Fluid Special, Nissan Matic
Fluid C, or D.
Checking Fluid LeakEGS0004C
Check hydraulic connections for any leak, crack, damage, loose-
ness, or wear.
1. Run engine until fluid temperature reaches 50 to 80°C (122 to
176°F) in reservoir tank. Keep engine speed at idle.
2. Turn steering wheel several times from stop to stop.
3. Turn the steering wheel clockwise or counter clockwise until it
reaches the stop and hold it for five seconds. Check for fluid
leak.
CAUTION:
Do not hold steering wheel at stop for 15 seconds or longer.
Otherwise, pump may be damaged.
4. If any leak is found on joint, loosen and retighten flair nut. Excessive tightening may damage O-ring,
washer, or connector.
Bleeding Hydraulic SystemEGS0004D
1. Lift vehicle.
2. Fill tank up to MAX mark. Turn steering wheel several times from stop to stop. Add fluid if fluid level goes
down. Repeat this step until there is no fluid decrease and no bubble in tank.
3. Start engine and repeat step above with engine at idle. Continue step until no decrease in fluid happens.
If bleeding is not complete, following symptoms can be observed.
●Bubbles are created in reservoir tank.
●Rattling noise can be heard from oil pump.
●Whining noise can be heard from oil pump.
Turn steering wheel slowly or stop vehicle. Sound of fluid movement may be heard from gear valve and
pump. This sound has nothing to do with steering performance or durability. HOT : Oil temperature 50 to 80°C (122 to 176°F)
COLD : Oil temperature 0 to 30°C (32 to 86°F)
