Brake Noise Problem Resolution New!
Duration: 1 Day
Upcoming open enrollment dates being scheduled. Please check back.
Hotel & Travel Information
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.
Prerequisites
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.

Eric Denys is currently the Global NVH Director, Brakes at Material Sciences Corporation in Canton, Michigan. His career spans 16 years at Federal-Mogul and Material Sciences Corporation with technical specialization in brake NVH. Mr. Denys has lead teams to achieve best-in-class in brake squeal on numerous vehicle lines and is the recipient of the 2001 Ford Global Customer Satisfaction Award for his work on high mileage brake squeal reduction. His work has been published in numerous national and international papers, and in an SAE book on Disc Brake Squeal. Eric is an active member of the SAE U.S. Working Group on Brake NVH. He received a B.S. in Mathematics from the Jean-Bart University, France and a M.S. in Mechanical Engineering from the University of Technology of Compiegne, France.
Dr. James K. Thompson is currently the Great Lakes Region Manager at Brüel & Kjaer. He was previously the Executive Director of NVH, Sales, and Marketing at Link Engineering Company where much of his work focused on vehicle braking system noise and vibration. Dr. Thompson's experience also includes positions as General Manager for Engineering Services for Automated Analysis Corporation, Chief Engineer for Acoustics and Engineering Mechanics for Goodyear Tire and Rubber Company, and faculty member of mechanical engineering at Louisiana State University. Dr. Thompson currently serves as the INCE-USA Vice President for Publications, Chairman of the SAE Brake NVH Standards Committee and Vice Chairman of the 2009 Noise and Vibration Conference. He has over 30 publications and regularly chairs sessions at the SAE Brake Colloquium, the SAE Noise and Vibration Conference, and the IMechE Braking Conference. Dr. Thompson received his B.S. and M.S. in Mechanical Engineering from Virginia Polytechnic Institute and State University and his Ph.D in Mechanical Engineering from Purdue University.
