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.
