PARKING BRAKE AND BRAKE PEDAL The front and rear disc-type brakes self-adjust every time the brake pedal is applied. WARNING See an INFINITI dealer for a brake system check if the brake pedal height does not return to normal. Brake pad wear indicators The disc brake pads on your vehicle have audible wear indicators. When a brake pad requires replacement, a high pitched scraping or screeching sound will be heard when the vehicle is in motion. The noise will be heard whether or not the brake pedal is depressed. Have the brakes checked as soon as possible if the wear indicator sound is heard. Under some driving or climate conditions, occasional brake squeak, squeal or other noise may be heard. Occasional brake noise during 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 "INFINITI Service and Maintenance Guide" booklet for maintenance intervals.
