Abstract
A backing plate comprises a front side configured to engage a friction material, a rear side opposite the front side, a first edge, a second edge generally opposing the first edge, and at least one channel disposed between the front side and the rear side and extending from the first edge toward the second edge. The rear side is configured to engage a caliper assembly. The backing plate is configured to achieve a resonant frequency that attenuates vibration.
