REAR DISC BRAKE

BRAKE PAD

BRAKE PAD : Inspection and Adjustment

INFOID:0000000009159846

INSPECTION

Remove tires. Refer to

WT-11, "Exploded View"

Check the thickness of brake pad from the inspection hole on
caliper. Use a scale to check if necessary.

Check the brake pad for whitening (carbonizing), uneven wear
and crack. Replace if necessary. (This work is recommended to
be performed by GT-R certified NISSAN dealer.)

CAUTION:

When replacing brake pad, replace all four brake pads
together. (Replacement depends on inspection results
shown below.)
• Replace four brake pads together with four disc rotors if the replacement of rear brake pad for a

rear disc rotor is the second one. (This work is recommended to be performed by GT-R certified
NISSAN dealer.)

• Replace right and left rear brake pads together with rear disc rotors if there is a judder. (This

work is recommended to be performed by GT-R certified NISSAN dealer.)

Install tires. Refer to

WT-11, "Exploded View"

ADJUSTMENT

Perform the following procedure when replacing the brake pad and disc rotor.

CAUTION:

• Be careful of the vehicle speed, because the effectiveness of the brake is decreased by the anti-cor-

rosion paint (silver color) applied for the contact surface with the brake pad for new disc rotor.

• Perform the procedure only on a safe road and be careful of the traffic conditions.

Drive on flat straight roads.

Depress the brake pedal to stop the vehicle within 3 to 5 seconds.

Cool the brake.

Repeat the above steps 1 to 3 until the operational feeling of brake pedal becomes equal to the pre-oper-
ation condition.

Check that the anti-corrosion paint (silver color) of disc rotor is eliminated. If the anti-corrosion paint (silver
color) remains, repeat the above steps 1 to 3.

If brake noise occurs, loosen the caliper mounting bolts after checking that the anti-corrosion paint (silver
color) does not remain at the disc rotor, and then perform the caliper position adjustment by tightening to
the specified torque. (This work is recommended to be performed by GT-R certified NISSAN dealer.)

CAUTION:

If the anti-corrosion paint (silver color) remains on the surface of brake pad, polish it with sandpa-
per until completely eliminated.

Use a brake tester to check that it is within the normal range.

REAR DISC BRAKE

When replacing rear disc rotors, replace them together with right and left rear brake pads. (Replace-
ment depends on inspection results shown below.)
• Rear disc rotors (a set of right and left) can be replaced alone only when a certified technician

checks for scratches and cracks and judges that the rear brake pads are reusable and when there
is no history of sport driving. (This work is recommended to be performed by GT-R certified NIS-
SAN dealer.)

• Replace right and left rear brake pads together with rear disc rotors if there is a judder. (This work

is recommended to be performed by GT-R certified NISSAN dealer.)

- The surface of the disc rotor for over burnt, uneven wear, cracks, serious damage, peel-off, remarkable

groove or vertical streaks.

- Confirm if there is no crack larger than 4mm around drilled hole of a disc rotor.
- The floating pin and nut for wear or damage.
- Any different groove in 0.3 mm (0.012 in) for disc rotor with brake noise.
• Check disc rotor nut (

) for rust.

• Check that brake pad replacement is not performed twice for a sin-

gle disc rotor.

Thickness

Remove tires. Refer to

WT-11, "Exploded View"

Check the thickness of the disc rotor using a micrometer.
Replace the disc rotor if the thickness is below the wear limit.

CAUTION:

When replacing rear disc rotors, replace them together with
right and left rear brake pads. (Replacement depends on
inspection results shown below.)
• Rear disc rotors (a set of right and left) can be replaced

alone only when a certified technician checks for
scratches and cracks and judges that the rear brake pads
are reusable and when there is no history of sport driving.
(This work is recommended to be performed by GT-R cer-
tified NISSAN dealer.)

• Replace right and left rear brake pads together with rear disc rotors if there is a judder. (This

work is recommended to be performed by GT-R certified NISSAN dealer.)

Install tires. Refer to

WT-11, "Exploded View"
