Patent ID: 7114420

Claim:
An improved vibration attenuator for use with a disk brake lathe designed for resurfacing a brake disk, the brake disk having a pair of disk surfaces, the disk brake lathe having, a pair of cutting tools, each mounted to an associated tool holder, the tool holders each adjustably positioning the cutting tool mounted thereto with respect to one of the disk surfaces, and a cutting head assembly which supports the tool holders and is movable to move the tool holders substantially radially with respect to the brake disk, the vibration attenuator having, a pair of friction pads each having a disk-engaging surface, which can be positioned to engage one of the disk surfaces of the brake disk, and a pair of legs, on each of which one of the friction pads is mounted, means for engaging the friction pads with the disk surfaces so as to apply a force to the friction pads holding them against the disk surfaces, the improvement comprising: a clip terminating in a first end region and a second end region, said first end region configured to pivotally engage one of the pair of legs, said second end region having a first protrusion spaced apart from said first end region and configured such that said first protrusion can be rotatably engaged with the other of the pair of legs, said first protrusion being further configured such that, when so engaged, said first protrusion forms a cradle for the other of the pair of legs and is spaced apart from said first end region so as to provide a first separation S 1 between the legs when so engaged, wherein said first separation S 1 is chosen such that, when said first protrusion is engaged with the other of the pair of legs, a bending moment is provided on the legs which generates a force which is greater than the force from the means for engaging the friction pads.
