Abstract:
A vibration attenuator for use with a disk brake lathe designed for resurfacing a 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 by a fastener having a fastener raised head of fastener height H, 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 comprising: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 pad lower surface having a pad recess therein, said pad recess being bounded in part by a recess distal wall and a recess proximal wall initiating at said pad lower surface, said recess distal wall and said recess proximal wall being separated by a recess width W sufficient to accommodate one of the fastener raised heads, said recess proximal wall being configured to be forcibly engaged by the fastener raised head when the cutting head assembly is moved to advance the tool holders substantially radially outwards, such forcible engagement causing said friction pad to move with the tool holder associated with the fastener, and said recess distal wall being configured to be forcibly engaged by the fastener raised head when the cutting head assembly is moved to move the tool holders substantially radially inwards, such forcible engagement causing said friction pad to move with the tool holder associated with the fastener; and spring means for forcibly engaging said friction pads with the disk surfaces.
