Application Note: Break Squealing

Optimizing automotive noise behavior is an important aspect in new vehicle designs. Using Polytec's innovative measurement technology, researchers at Robert Bosch GmbH have managed to track down the causes of undesired noises when braking.

Modern brake systems in cars are more powerful than ever and distinguish themselves through functional diversity which not very long ago would have appeared impossible. So that all components in a braking system still work together as well as possible despite the increase in complexity, it is necessary to have a deep understanding of the system. Bosch manufactures all the most important components itself and can thus offer car manufacturers complete solutions from a single source.

When developing braking systems, Bosch does not only optimize the function of the individual components, they also focus on the way it all works together as a system and on the inter- Hot on the Trail of Squealing Brakes faces with the whole vehicle. Sound knowledge of the vibration characteristics of their products makes it possible for the Bosch engineers to minimize the risk of squealing and rumbling brakes which then contributes towards increasing comfort levels for the driver and passengers. As the world's largest manufacturer of brake and brake control systems, Bosch offers car manufacturers complete brake assemblies and systems. This includes products for vehicle safety, such as an Antilock Braking System (ABS), Traction Control System (TCS) and the Electronic Stability Program (ESP).
