The final section of the chapter deals with the particular problems of brake noise and vibration, the latter affecting not only the brake itself but also the entire chassis due to transmission of the vibration.
The noise can have structural (gear-slip, bearings, or other moving surfaces touching), aero-acoustic, load-induced or electromagnetic sources. Each of these physical mechanisms can interact and be fed back through the structural vibrations of the physical system, so it becomes difficult to separate noise sources in a meaningful way.
