An improved tool for attenuating vibration in a disk brake rotor during the machining (or facing) thereof using a disk brake lathe is described. In its most basic form, embodiments of the tool comprise a pair of substantially linear and parallel spaced apart legs that are fixedly coupled together by way of a coupling section proximate their proximal ends and have opposing pads attached to the opposing distal ends. An adjustable clamping mechanism is also provided through which the distance between the legs can be varied and/or the biasing force applied against opposing brake rotor surfaces can be varied by way of the legs acting through the pads.

The tool of claim 1, wherein the pads are comprised of an automotive brake pad friction material. 3. The tool of claim 1, wherein the first rod comprises steel and has a diameter of at least 0.18″. 4. The tool of claim 3, wherein the second rod comprises steel and has a diameter of at least 0.15″. 5. The tool of claim 1, wherein when in an uncompressed state, the opposing planar surfaces of the respective pair of pads are spaced apart 0.50-0.80″. 6. The tool of claim 1, wherein the left and right first rod legs are spaced apart from the left and right second rod legs and the respective rod legs are generally parallel to each other. 7. The tool of claim 1 wherein the left and right compression brackets are adapted to slide along the respective left and right first rod legs in the first bore. 8. The tool of claim 1, wherein the adjustable fastener includes a threaded bolt, the threaded bolt being received through a third bore in each of the left and right compression brackets, the third bore being generally perpendicular to the first bore. 9. The tool of claim 6, wherein the adjustable fastener includes a threaded bolt, the threaded bolt being received through a third bore in each of the left and right compression brackets, the third bore being generally perpendicular to the first bore and being located between the first and second bores. 10. The tool of claim 8, wherein the adjustable fastener further includes a wing nut. 11. The tool of claim 1, furthering including a lanyard, the lanyard being slidably secured to one of the first and second rods. 12. The tool of claim 1 further comprising one or two polymeric sheaths, each polymeric sheath being received over a curved portion of either the first or second rod. 13. A tool for attenuating vibrations in a disc brake rotor during machining of surfaces of the rotor, the tool comprising: a u-shaped first rod having left and right first rod legs and left and right first rod ends, the left and right first rod legs being spaced apart from each other and being generally parallel to each other; left and right pads, the left and right pads each having a generally planar surface facing a generally planar surface of the other pad, the left pad being attached to the left first rod leg proximate the left first rod end, and the right pad being attached to the right first rod leg proximate the right first rod end; and an infinitely adjustable clamp, the clamp adapted to move the first and second legs and the associated planer surfaces of the left and right pads towards each other and against the brake when tightened to apply a compressive force against opposing surfaces of the brake rotor, wherein the clamp is adapted to slide along the left and right legs, and wherein the clamp comprises: (i) a left block; (ii) a right block; and (iii) a u-shaped second rod with respective left and right second rod legs having left and right second rod ends; wherein each block includes a first bore extending therethrough through which a respective left or right first rod leg is slidably received, and wherein each block is attached to a respective left or right second rod end. 14. The tool of claim 13, wherein the clamp comprises: (i) a left bore extending into the left block and therethrough; and (ii) a right bore extending into the right block and therethrough, wherein the left and right first rod legs are slidably received in the respective left and right bores, and wherein each of the left and right blocks are further inhibited from rotating about a longitudinal axis of the respective left and right first rod legs. 15.
