INFINITI: 4-PISTON BRAKE CALIPER BRAKE JUDDER
This bulletin has been amended to add models to Applied Vehicles. Please discard the previous version

APPLIED VEHICLES:
VIN AND DATE:

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.

SERVICE PROCEDURE
1. Inspect the front brake rotors to determine if “turning” (“machining”) is possible or if replacement is necessary.


Refer to the Electronic Service Manual (ESM), section BR-Brake System, for rotor inspection information.



If rotor machining is possible, make sure to use the ProCut PFM Series on-car brake lathe.



If rotor replacement is necessary, replace both front rotors as a set.
 Use the rotor listed in FAST or your electronic parts catalog.

2. Replace the front brake pads (see PARTS INFORMATION).


Refer to the ESM, section BR-Brake System, for front brake pad replacement information.

3. Replace both pad pins in both front 4-piston calipers (see PARTS INFORMATION).


Refer to the ESM, section BR-Brake System, for 4-piston pad pin replacement information.
