Summary
IF YOU CONFIRM: "Brake Judder" during braking, especially when braking at highway speeds. Symptoms of "brake judder": - steering wheel shake - body vibration - brake pedal pulsation IMPORTANT NOTES: If any symptom above occurs when cruising or coasting (not braking), it is not "Brake Judder" and may be tire/wheel related. DO NOT CONFUSE "Brake Judder" with the rapid consistent-speed pedal pulsation that may be felt and only occurs when ABS is activated during hard braking or on slippery road surfaces. ACTION: 1. Inspect the front brake rotors to determine if "machining" ("turning") is possible or if replacement is necessary. 2. Replace both pad pins in both front 4-piston calipers (see PARTS INFORMATION). 3. Replace the front brake pads (see PARTS INFORMATION). See this bulletin for further detail.

Please see page 2 for Applied Vehicles, VIN, and Dates
IF YOU CONFIRM:
“Brake Judder” during braking, especially when braking at highway speeds.
Symptoms of “brake judder”:
steering wheel shake
body vibration
brake pedal pulsation
IMPORTANT NOTES:
If any symptom above occurs when cruising or coasting (not braking), it is not “Brake Judder” and may be
tire/wheel related. Refer to ASIST for further diagnostic assistance.
DO NOT CONFUSE “Brake Judder” with the rapid consistent-speed pedal pulsation that may be felt and
only occurs when ABS is activated during hard braking or on slippery road surfaces. In contrast, the pedal
pulsation of “Brake Judder” may occur with light to moderate braking experienced during normal driving
conditions, and the pulsation rate will vary (faster or slower) with vehicle speed.
ACTION:
1. Inspect the front brake rotors to determine if “machining” (“turning”) is possible or if replacement is necessary.
2. Replace both pad pins in both front 4-piston calipers (see PARTS INFORMATION).
3. Replace the front brake pads (see PARTS INFORMATION).
The purpose of ACTION (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the
entire SERVICE PROCEDURE as it contains information that is essential to successfully completing this repair.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals
who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described
condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti dealer to determine if this applies to your vehicle.
