SERVICE INFORMATION

Brake judder may be described as steering wheel/body vibration or brake pedal pulsation when braking (especially during high speed braking). Brake judder may be created by excessive "thickness variation" of the brake rotors. Thickness variation is usually the result of excessive rotor run-out. While brake judder is usually associated with the front brake rotors, it may occur in the rear brake rotors as well.

NOTE:
Brake judder repair, as outlined in this bulletin, is covered by the 3 year, 36,000 mile warranty for these vehicles.

NOTE:
The ONLY way to eliminate brake judder caused by the front brakes is to turn the front disc brake rotors using an on-car brake lathe (such as the ProCut(TM) PFM900* or equivalent). The on-car brake lathe is more effective in reducing brake rotor run out than the conventional off-car lathe method. This is true even if the rotors are indexed after they are turned using the off-car method. The on-car brake lathe is a required essential tool, and must be used when turning front brake rotors as part of a warranty repair.
