light to moderate stops is normal and does not affect the function or performance of the brake system. Proper brake inspection intervals should be followed. For additional information, see the maintenance log section of your "NISSAN Service and Maintenance Guide" for maintenance intervals. REPLACING THE BRAKE PADS To ensure maximum performance, the brake pads and disc rotors must be replaced as a set. Never replace or use only the brake pads on their own. When replacement is required, we recommend seeing a GT-R certified NISSAN dealer for servicing. . When the brake disc rotor undergoes thermal expansion, a rumbling 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 cease when the temperature decreases. NOTE: . This vehicle is equipped with a high performance braking system and includes cross-drilled floating rotors and radial-mounted six-piston monoblock calipers. This helps to achieve excellent stopping performance and fade-resistance. Replace all four sets of brake pads and disc rotors at the same time to maintain maximum brake performance. 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 light rattling sound may be heard from the brake pad. This does not indicate that there is a malfunction. HIGH PERFORMANCE BRAKE SYSTEM This vehicle is equipped with high performance brake pads that provide appropriate braking force in a broad range of driving environments. Due to the material used for the brake pads, the road wheels may become more easily covered by brake dust, however this does not indicate that there is a malfunction. Frequent hard braking may cause scorching of the brake pads. This will require the brake pads to be replaced, even if the wear limit has not been reached. Have the brake pads and disc rotors inspected at the regular vehicle inspections. For more details, contact a GT-R certified NISSAN dealer. . Maintenance and do-it-yourself 8-21
