brakes are applied when the vehicle is shut off, the rotor and pads can rust together, even when the brake pads are dry. - If the brakes are wet when the vehicle is parked and the parking brake is applied for a long time. - The hill start assist system can apply the brakes even if the brake pedal is not depressed. The brake pads and rotors can rust together if the parking procedure previously described is not followed. Contact a GT-R certified NISSAN dealer if the brake pads and brake rotor have rusted together. light rattling sound may be heard from the brake pad. This does not indicate that there is a malfunction. . When the brake disc rotor undergoes thermal expansion, a ticking noise may be heard from the engaging portion of the wheel and the brake disc rotor. This does not indicate that there is a malfunction. The noise will reduce when the temperature decreases. In addition to noise resulting from uneven tire wear discussed in the previous section, the GT-R tires are more rigid than a typical passenger car tire and are made from a specially formulated rubber to maximize the vehicle's performance capabilities. These characteristics cause the GT-R tires to have more road noise than a typical passenger car tire. This road noise is normal. Due to the performance capabilities and requirements of the GT-R, the sequential 6speed dual clutch transmission is unlike a typical automatic transmission. You will likely hear mechanical sounds from the transmission, particularly at slow speeds and at idle. This condition is normal. strongly than conventional brake pads to withstand the high brake temperatures. The friction material and backing plate expand due to heat at different rates. Some cracks may be on the surface of the friction material due to the differences in expansion rates and the strong bond between the friction material and backing plate. The cracks do not indicate the brake pads need to be replaced. BRAKE DUST This vehicle is equipped with high performance brakes, and the characteristics of the brake pad material may cause more brake dust than other vehicles. NISSAN recommends a wheel coating that helps prevent the brake dust from sticking to the wheels. Contact a GT-R certified NISSAN dealer for more details. . NOTICE Have the brake pads and/or rotors quenched when the brake pads are replaced to reduce the possibility of the rotors and brake pads rusting. For detailed information about quenching, contact a GT-R certified NISSAN dealer. . To maintain steady braking performance in both extremely high and low temperatures, the gap between the brake pad and caliper is larger than normal and large-size brake pads are used. When driving over a bump, a . MECHANICAL LIMITED SLIP DIFFERENTIAL (LSD) CHARACTERISTICS The differential oil has a high viscosity and is very thick when cold. If the vehicle accelerates from a stop with the steering wheel turned in cold temperatures, the inner wheel tire may slip and some noise or vibration may be heard. This phenomenon is unique to vehicles equipped with the Limited Slip Differential (LSD). When the steering wheel is returned to the straightahead position or the differential oil warms up, the noise and vibration decrease.
