## NHTSA's summary

Concern: Customer reports that vehicle brakes squeal. Information: Remember that brake squeal is a normal result of different factors acting upon the brake system and does not constitute a defect. ? Normal brake noises, such as squeal, occur under a narrow set of operating condition. ? An example would be low speed, light brake pedal application. ? Abnormal brake noises occur under wider operating conditions. ? An example would be during light or heavy braking at any speed or temperature In the interest of customer satisfaction, we will perform a brake inspection to assure the customer that there are no safety or performance issues associated with brake noise. Porsche will cover this inspection under warranty. The customer may also refer to the owner?s manual section on Driving and Driving Safety regarding brake squeal.
