We suggest an effective way of reducing drum-type brake noises. We noted that noises are most likely to occur when the eigenvectors and eigenvalues of the brake drum and brake shoes are close to the coupled vibration frequency. It was also noted that the eigenvectors of the leading and trailing brake shoes are independent from each other. Based on these findings, the two shoes were rendered asymmetric in rigidity, causing the eigenvectors and eigenvalues of either of the two shoes to exist apart from those of the drum in fundamental to high-order modes. This in turn effectively prevents increase in the magnitude of coupled vibration of drum and shoes, and significantly reduces brake noise level.
