NTB16-024	2021-05-24. Service bulletin. 370Z; 4-Piston front caliper brake Judder
NTB16024	2021-05-10. Service bulletin. 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.

NTB15060	2021-05-10. Service bulletin. SERVICE INFORMATION When servicing run flat tires or low profile tires: - Special equipment and procedures are required to avoid damage. - Specifically, Tire Pressure Monitor transmitters (TPMS sensors) can be damaged when improperly dismounting and mounting tires. - TPMS sensors becoming damaged during mounting or dismounting tires are not covered under warranty. - To avoid such damage, ensure that the tire changer being used and the operator of the tire changer is capable of servicing run flat and low profile tires. - Operator?s manuals for such tire changers must be followed. See this bulletin for further detail.
NTB13026B	2021-05-10. Service bulletin. IF YOU CONFIRM: The clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor OR the customer states the clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor AND there are no leaks in the clutch hydraulic system. ACTION: Flush (remove) ALL existing clutch hydraulic system fluid, and refill with GT-R R35 Special Brake Fluid (see PARTS INFORMATION). - Use the SERVICE PROCEDURE in this bulletin for proper flush and refill procedure. See this bulletin for further detail.
NTB04094A	2021-05-10. Service bulletin. If YOU CONFIRM: A vehicle needs to have the brake rotors resurfaced (front or rear). ACTION: Use the ProCut PFM Series on-car brake lathe to perform brake rotor resurfacing and follow the tips listed in this bulletin. - The ProCut PFM Series brake lathe has been chosen as the approved tool for rotor resurfacing. - The ProCut PFM Series brake lathe can be ordered from TECH-MATE at 1-800-662-2001. - ProCut technical support or service can be obtained by calling 1-800-543-6618. NOTE: Brake rotors may need to be resurfaced during routine brake repair or for brake "judder" incidents. - Brake judder: A brake pedal pulsation and/or steering wheel shimmy when braking that occurs when there is too much thickness variation of the brake rotors (see NTB00-033). See this bulletin for further detail.
NTB00033E	2021-05-10. Service bulletin. SERVICE INFORMATION - This bulletin is to assist you in responding to customer questions about brake operation, and provides diagnostic and repair information for each item listed, if any should occur. - Most brake incidents fall into the following categories: a. Brake Noise: A squeak, squeal, clunk, or groan that occurs when the brakes are applied or released. b. Brake Judder: A vibration that can be felt in the vehicle, steering wheel or brake pedal when the brakes are applied. c. Pedal Feel: The effort needed to operate the brakes is too high or too low. SERVICE PROCEDURE 1. Verify the condition by road testing the vehicle with the customer. 2. Determine the specific brake incident based on the description in the Service Information above. 3. Follow the appropriate repair procedure(s), listed on the following pages, for your specific incident. See this bulletin for further details.

NTB16-024	2016-06-22. Service bulletin. 370Z; 4-PISTON FRONT CALIPER BRAKE JUDDER “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.
