Holographic analysis of vibrations on squealing drum brake systems is a useful method to localize vibration sources on drum brake components. The results described in this paper are obtained by ...

Disc brakes resemble hand brakes on a bicycle, where pulling on the brake lever forces a plier-like device to squeeze rubber blocks against the rim of the wheel to stop the car. Drum brakes are a ...

The combination of vibrational analysis, empirical testing, and consistent test methodology led to the understanding and elimination of low frequency drum brake noise. Each of the above items served ...

Back in the '60s, drum brakes didn't seem that bad since most cars were hobbled with the same lack of stopping prowess. Fast forward a few decades and it matters a bit more that it takes you an ...
