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.
