Studying Brake Noise with Ultra Slow Motion Photography 650489

By drastically slowing down and magnifying the vibration of components associated with brake noise, macrographic ultra slow motion photography affords a valuable tool to study the causes of this phenomenon. In combination with tape recording techniques, results obtained substantiate the concept of a “slip-stick” condition producing noise, and suggest a mechanism, related to the natural frequency of the stationary elements of the brake system, to explain the cause of at least one kind of brake noise.
