  • Split backplate for noise suppression in brake pad assemblies
    Patent number: 5842546
    Abstract: A brake pad assembly is provided having a split backplate design comprising a damping layer disposed between two metal plates which are mechanically fastened together such that the plates are slightly slidable relative to each other to allow independent vibration of the two plates. The two metal plates are provided with a ratio of the thickness of the plate farther from the friction material to the plate closer to the friction material of at least 1.50. The damping layer is formed of a non-compressible, non-metal, heat-resistant material such as glass fiber cloth, mineral fiber cloth, ceramic fiber cloth, aramid fiber cloth, or graphite fiber cloth, and preferably has a low coefficient of friction. The plates are mechanically fastened together by rivets, pins or the like.
