Brake Noise Problem Resolution C0831

Brake noise is one of the highest ranked complaints of car owners. Grunts, groans, squeaks, and squeals are common descriptions of the annoying problem which brake engineers spend many hours trying to resolve. Consumer expectations and the high cost of warranty repairs are pushing the optimization of brake NVH performance. This course will provide you with an overview of the various damping mechanisms and tools for analyzing and reducing brake noise. A significant component of this course is the inclusion of case studies which will demonstrate how brake noise squeal issues have been successfully resolved.

Learning Objectives
By attending this seminar, you will be able to:
  • Describe the various brake shim damping mechanisms
  • Compare the various brake shims available in the market place
  • Describe the various tools available to reduce brake noise
  • Utilize lessons learned in various brake noise problem case studies

Who Should Attend
The course is designed for a wide range of personnel from the brake test engineer who seeks to understand more about brake NVH to the experienced brake NVH/design engineer who wishes to know more about potential solutions. Anyone involved in the resolution of brake noise problems will find this course helpful.

Participants should be familiar with brake hardware, basic terminology, and brake NVH measurement and testing. Previous attendance at SAE seminar ID# C0509, Hydraulic Brakes for Passenger Cars and Light Trucks and ID# C0802 Brake, NVH, Measurement, and Testing or equivalent experience and knowledge are highly recommended.
