1.

Replace gasket.

2.

If oil leakage continues even after replace the transmission as-
sembly. (This work is recommended to be performed by GT-R 
certified NISSAN dealer.)

E: Guide hole

1.

Replace side oil seal (left side). (This work is recommended to be

Always replace side oil seal (left side) together with side 
flange (left side). [If side oil seal (left side) is abnormal, then 
side flange (left side) may also be abnormal.]

2.

If oil leakage continues even after replacing side oil seal, check 
guide hole. If guide hole is abnormal, replace transmission as-
sembly. (This work is recommended to be performed by GT-R 
certified NISSAN dealer.)

F: Air vent

Replace the transmission assembly. (This work is recommended to be 
performed by GT-R certified NISSAN dealer.)

Transmission assembly 
(single unit)

G: Breather

Clean and wipe spouted oil with a part cleaner. Fill with oil to the spec-
ified oil level, if necessary.

Smears

*3

Each part on the final drive assembly, includ-
ing the parts requiring oil leakage check.

Use part cleaner or the equivalent to wipe out smeared oil. Then, check 
for oil leakage.

*3: When the oil does not drop

• Visually check transmission assembly surrounding area (oil seal, drain plug, filler plug, transmission case,

etc.) for smears and leakage of transmission oil. Refer to 

MA-32, "TRANSMISSION OIL : Inspection"

.

OIL LEVEL

CAUTION:

Oil volume cannot be checked by oil level height.

1.

Remove filler plug (1) and gasket.

CAUTION:

Never start engine while checking oil level.

2.

Insert wire (A) etc. from filler plug mounting hole to confirm if the
oil attaches.
• If oil does not attach at the end of the wire, confirm that there

is not leakage, then refill the oil. (This work is recommended to
be performed by GT-R certified NISSAN dealer.)

CAUTION:

Prevent foreign matter from getting into final drive.

3.

Set a gasket on filler plug and install it on final drive, and then
tighten to the specified torque.

CAUTION:

Never reuse gasket.

BRAKE LINES AND CABLES

BRAKE LINES AND CABLES : Inspection

INFOID:0000000009161789

• Check brake fluid lines and parking brake cables for improper

attachment, leaks, chafing, abrasions, deterioration, etc.

BRAKE FLUID

BRAKE FLUID : Inspection

INFOID:0000000009161790

BRAKE FLUID LEVEL

• Check that the fluid level in the reservoir tank is within the specified

range (MAX – MIN lines). 

• Visually check for any brake fluid leakage around the reservoir

tank. 

• Check the brake system for any leakage if the fluid level is

extremely low (lower than MIN). 

• Check the brake system for fluid leakage if the warning lamp

remains illuminated even after the parking brake lever is released. 

• Check the reservoir tank for the mixing of foreign matter (e.g. dust)

and oils other than brake fluid.

CHASSIS MAINTENANCE

1.

Check the brake line (tube and hose) for any cracks or damage. 

CAUTION:

Replace with new ones if necessary. 

2.

Depress the brake pedal with a force of 785 N (80 kg, 176 lb) and hold down the pedal for approximately
5 seconds with the engine running. Check for any fluid leakage. 

CAUTION:

Retighten each part to the specified torque and repair any abnormal (damaged, worn, or deformed)
part if any fluid leakage is present. 

BRAKE FLUID : Draining

INFOID:0000000009161791

CAUTION:

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

out immediately and wash with water if it gets on a painted surface. 

• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-

nector or the battery negative terminal before performing work. 

• Wrap the flare nut wrench with waste cloth to protect the caliper from damage. 
• If the brake fluid adheres to the caliper or disc rotor, quickly wipe it out. 

1.

Remove tires. Refer to 

WT-11, "Exploded View"

.

2.

Connect a vinyl tube to the bleeder valve. 

3.

Depress the brake pedal and loosen the bleeder valve to gradually discharge brake fluid. 

BRAKE FLUID : Refilling

INFOID:0000000009161792

CAUTION:

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

out immediately and wash with water if it gets on a painted surface. 

• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-

nector or the battery negative terminal before performing work. 

• Wrap the flare nut wrench with waste cloth to protect the caliper from damage. 
• If the brake fluid adheres to the caliper or disc rotor, quickly wipe it out. 
• Never allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.
• Since brake fluid is susceptible to deterioration from moisture, discard brake fluid remaining in the

container.

1.

Check that there is no foreign material in the reservoir tank, and refill the brake fluid with new one. 

CAUTION:

Never reuse drained brake fluid. 

2.

Loosen the bleeder valve, slowly depress the brake pedal to the full stroke, and then release the pedal.
Repeat this operation at intervals of 2 or 3 seconds until all of the brake fluid is discharged. Then close the
bleeder valve with the brake pedal depressed. Repeat the same work on each wheel.

3.

Perform the air bleeding. Refer to 

BR-10, "Bleeding Brake System"

.
