BRAKE MASTER CYLINDER
On-Board Inspection INFOID:0000000004305901
LEAK INSPECTION • Check for leaks around the master cylinder installation surf ace, the reservoir tank installation surface, and all
the brake tube connections.
Removal and Installation INFOID:0000000004305902
CAUTION:
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe th em with cloth and wash it away with water.
REMOVAL 1. Drain the brake fluid. Refer to BR-9, " Drain and Refill " .
2. Remove the battery. Refer to SC-7, " Removal and Installation " .
3. Remove the air duct. Refer to EM-139, " Removal and Installation " .
4. Remove the air cleaner. Refer to EM-139, " Removal and Installation " .
5. Disconnect the brake fluid level switch harness connector.
6. Disconnect the clutch hose from the reservoir tank, if equipped.
7. Remove the brake tube from master cylinder using a suitable tool.
8. Remove the master cylinder assembly nuts, and remove master cylinder assembly. 1. Reservoir tank 2. Master cylinder 3. Brake booster
4. Clevis 5. Spacer 6. Gasket

Fluids and Lubricants " .
• Never reuse drained brake fluid.
• Check if the rod of primary piston has dust or scratches.
1. Install master cylinder to brake booster assembly, and tighten nuts to the specified torque.
CAUTION:
• Do not damage or strain rod of primary piston.
• Apply silicone grease for O-ring, primary piston rod and to inside of booster.
2. Install brake tube to master cylinder, and temporarily tighten the flare nuts on the brake tube to master cyl-
inder by hand.
3. Install brake tube to brake hose, then tighten flare nut to the specified torque using a flare nut torque
wrench. Refer to BR-11, " Hydraulic Circuit " .
4. Connect the clutch hose to the reservoir tank, if equipped.
5. Connect brake fluid level switch harness connector.
6. Refill with new brake fluid and bleed the air from the brake hydraulic system. Refer toBR-9, " Bleeding
Brake System " .

PRECAUTIONS
Precaution for Supplemental Restraint Syst em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004802358
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 SRS and SB section of this Service Man-
ual.
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 incorrect 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 SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution for Procedure without Cowl Top Cover INFOID:0000000004305163
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Service Notice or Precaution INFOID:0000000004305164
• Use recommended brake fluid when adding flui d to the clutch reservoir tank. Refer to MA-14 .
• Never reuse fluid drained from clutch system.
• Be careful not to splash brake fluid on painted areas.
• Use new brake fluid to clean or wash all part s of master cylinder and operating cylinder.
• Never use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic sys-
tem.
• If transaxle assembly is removed from the vehicle , always replace CSC (Concentric slave cylinder).
Return CSC to original position to remove transaxle assembly. Dust on clutch disc sliding parts may
damage CSC seal and may cause clutch fluid leakage.
• Do not disassemble clutch master cylinder and CSC.
WARNING:
After cleaning clutch disc, clean it with a dust collector. Do not use compressed air. PIIB3706J
