 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-corrosion 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.

    1.Drive on flat straight roads.
    2.Depress the brake pedal to stop the vehicle within 3 to 5 seconds.
    3.Cool the brake.
    4.Repeat the above steps 1 to 3 until the operational feeling of brake pedal becomes equal to the pre-operation condition.
    5.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.
    6.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. Refer to Removal and Installation (GT-R certified NISSAN dealer).
    7.Use a brake tester to check that it is within the normal range.
