BRAKE PEDAL

BRAKE PEDALPFP:46501
Inspection and AdjustmentBFS000BG
Play and clearance inspection between brake pedal and floor panel with pedal depressed.

Check brake pedal height from dash lower panel (1).

Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch, brake switch and/or ASCD cancel
switch by turning it counterclockwise by 45°.
2. Loosen lock nut “A” on input rod, then rotate input rod to set,
brake pedal to the specified height, and tighten lock nut “A”.
Refer to BR-22, "
COMPONENTS" .
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch,
brake switch and/or ASCD cancel switch until its threaded end
contacts bracket.
4. With threaded end of stop lamp switch, brake switch and/or
ASCD cancel switch contacting bracket, rotate switch clockwise
by 45° to secure.
CAUTION:

Make sure that the clearance “C” between bracket and
end of stop lamp switch, brake switch and/or ASCD can-
cel switch is within the standard.

When locking stop lamp switch and ASCD cancel switch,
pull brake pedal to avoid moving toward the direction
where switches are being pressed.
5. Check the pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depressed height.

CAUTION:
If leakage occurs around brake tube and hose connections, retighten or, if damaged part is detected,
replace the damage part.
1. Check brake hoses, brake tubes, and connections for fluid leakage, damage, twists, deformation, contact
with other parts, and loose connections.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately
5 seconds, check for fluid leak each part.

BRAKE BOOSTERPFP:47200
On-Board Inspection and ServiceBFS000BS
OPERATION CHECK
With engine stopped, change the vacuum to the atmospheric pres-
sure by depressing brake pedal several times. Then with brake
pedal fully depressed, start engine and when the vacuum pressure
reaches the standard, make sure that clearance between brake
pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIR TIGHT CHECK

Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure
distance between brake pedal and floor panel gradually
increases.

Depress brake pedal while engine is running, and stop engine
with brake pedal is depressed. Brake pedal stroke should not
change after holding brake pedal down for 30 seconds.
CAUTION:
Depressing brake pedal interval is approximately at intervals 5
seconds.

[ABS]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000CK
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 SystemBFS000CL

Recommended fluid is brake fluid “DOT 3” or “DOT 4”. Refer to MA-14, "RECOMMENDED FLUIDS AND
LUBRICANTS" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

Never use mineral oils such as gasoline or kerosene. They will
ruin rubber parts of the hydraulic system.

Using a flare nut wrench when removing flare nuts, and use a
flare nut torque wrench when tighten brake tube flare nuts.

When installing brake tubes, 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 negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlBFS000CM

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal condition of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
