Abstract: A vibration attenuator for a disk brake lathe has two friction pads, each having a pad recess with a distal wall and a proximal wall. When the pads are placed against a brake disk, the recesses are placed over raised heads of fasteners that affix cutting tools of the lathe to adjustable tool holders. When the tool holders are moved radially outwards across the brake disk, the fastener raised heads engage the recess proximal walls and move the pads along with the cutting tools, and also serve to couple the pads with the cutting tools to dampen vibrations. Similarly, when the tool holders are moved radially inwards, the fastener raised heads engage the recess distal walls to move the pads along with the cutting tools. A U-shaped member having a tension spring extending between two legs on which the pads are mounted forcibly engages the pads with the brake disk.
