A vibration damper for inhibiting harmonic vibrations in a brake rotor during resurfacing operations is made by forming an elastic tube or band into a closed loop with tubular iron weights strung thereon before the loop is joined. The elastic tube is first stretched lengthwise to make its lateral dimensions small enough to thread through the tubular weights, and the tube is then relaxed and its ends are interconnected. The elasticity of the thus formed damper holds the tubular iron weights in preselected position on the tube and also allows it to be stretched over the edge of brake rotors which vary considerably in size. The resilient tube of the damper resiliently engages the outer periphery of the rotor to retain the weights in place on the periphery of the rotor as the weights damp the vibrations which occur while the spinning rotor is having its radial braking surfaces machined.
