First, the disc should be inspected for warping or cracks — if any are found, the disc must be replaced.
If the disc only shows shallow grooves, light scratches, emits grinding noises, causes the car to vibrate when braking, or has a shiny glazed surface, it may be suitable for resurfacing.
However, brake discs cannot be resurfaced indefinitely. They have a minimum thickness (usually stamped on the edge of the rotor), and if the disc falls below this limit, braking performance will be compromised.
