−− Role and purpose of brake shims −− Different types of brake shims −− Brake shims damping mechanisms • Tools for Brake Noise Analysis/Reduction −− Brake noise categorization −− Solution strategy −− Investigative tools — testing; simulation • Squeal −− Brake pad design optimization −− Pressure distribution optimization −− Low frequency squeal • Moan/Groan −− After-stop noise program — Problem identification; Transmission of the road to the lab; Measurement systems; Root cause analysis; Solution • Questions and Answers Session Brake System Balance for Passenger Cars and Light Trucks 6 Hours | Web Seminar I.D.# WB1413 Designing a brake system requires the ability to balance a multitude of parameters against the required tradeoffs of system weight, system cost, and system performance. Understanding the basic fundamentals of how each brake component attribute contributes to the overall Force vs Deceleration behavior of the vehicle is critical to the design and release of a safe, legal and optimized system for today’s vehicles. Brake balance also is a contributing factor to other chassis control and safety systems, such as regenerative braking, ABS, and electronic brake distri- bution (EBD).

Brake Noise Problem Resolution 1 Day | Classroom Seminar I.D.# 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.
