UNEVEN WEAR OF TIRES The GT-R is equipped with high performance, low profile, run-flat tires that are optimized for performance and handling. The life of these tires will be less than those of tires installed on a typical vehicle, and you are likely to experience uneven tire wear and tire noise regardless of the type of tire used. caused when the brake pads absorb moisture, and the noise stops after the brake is applied several times. . A screeching noise may also be heard when the brake pedal is depressed: - When repeatedly applying gentle braking, especially on a curve at a low speed, or - When the brake rotors have circular scores with the brake temperature high. . The GT-R uses brake pad materials that have high metallic content. The brake pad material helps maintain braking performance in a wide range of weather and driving conditions. For the first 3,000 miles (5,000 km) of the vehicle's service life, and for the first 3,000 miles (5,000 km) after a brake replacement, the brake pad to brake rotor clearance is very small. When parking, apply the parking P brake and move the shift lever to the & position. Idle the engine for more than 20 seconds without depressing the brake pedal. This allows the brake pads to move away from the rotor so the pad does not contact the rotor. Additionally, the brakes must be dry before parking the vehicle after driving on wet roads or after washing the vehicle. If the roads are wet, lightly apply the brakes for a short distance before parking the vehicle to dry the brakes. After washing the vehicle, dry the brakes by driving on a dry road for a few miles and apply the brakes normally based on traffic and road conditions. The metallic brake pads and brake disc rotor may rust together when the brakes are not applied: - If the vehicle is not idled for 20 seconds without the brakes applied, or if the NOISES ARE HEARD WHILE DRIVING . The GT-R brake pads use material that provides a high amount of braking power even in high temperatures. This material can cause an intermittent screeching noise just before the vehicle comes to a stop when the brakes are gently applied. The noise decreases as the brake pads wear. However, the additional brake pad break-in may decrease the noise. Contact a GT-R certified NISSAN dealer. A screeching noise may be heard when the brake pedal is depressed: - When driving the vehicle for the first time in the morning, - After leaving the vehicle parked for extended periods of time, or - When the vehicle is damp following rain showers or washing the vehicle. These sounds are normal. The noise is WARNING Follow the instructions below when parking the vehicle to help prevent the brake rotor and brake pads from rusting together. Failure to follow the instructions could cause the rotor and pads to rust together. If the rotor and pads rust together, there may be a popping noise and some vibration when the vehicle is driven, a wheel may not roll correctly, or the brake pads could be damaged. If the pads are damaged, this may reduce the effectiveness of the brake system which could cause a collision, serious personal injury or death. . GTR-16 GT-R Overview
