Volkswagen Brake Rotor Resurfacing Basics

Brake rotor resurfacing starts with the use of a brake lathe that is applied to the surface of the rotor. As the rotor passes over, a tiny surface layer is shaved off and takes with it small imperfections to leave a smoother surface behind. The process removes issues like pitting, rust and other flaws. When this service can be completed, you do not need to purchase new rotors.

Reasons for Brake rotor Resurfacing

The type of imperfections brake rotor resurfacing can remove, such as pitting or rust spots, cause unevenness on the surface of the brakes and can impact your braking. Some flaws lead to vibrations while braking and can also contribute to the unnecessarily fast depletion of your brake pad material. Flaws also limit the contact points between the brake pad and the rotor, and this minimizes your stopping ability.

Brake Rotor Replacement Vs. Resurfacing

Many brake rotors can be resurfaced at least one time, but there are newer options that cannot. Brake rotors need to be at a minimum set thickness specified by the manufacturer in order to safely function in your vehicle. If there is material above and beyond this threshold, your rotors can be resurfaced until this level is reached. When it becomes too thin, resurfacing is no longer safe. Some newer brake rotors are manufactured without the excess material that allows for resurfacing, making replacement necessary.
