Overall, it is generally more cost effective for a car owner to just replace the rotors. Machining rotors may be the less expensive alternative, but by saving $50-$100, you’re typically increasing the chances of an issue developing later.

Although it is commonly stated that new rotors should never be machined, in some situations, a new rotor should be machined to fit the vehicle using an on-the-car brake lathe. On fresh rotors, using an on-car lathe can assist decrease run out.
Because brakes are such an important part of vehicle safety, it is essential that you test them on a regular basis, not only when you suspect anything is amiss. At JDM P/L, we inspect the brakes and rotors on every vehicle we service.
Rotors may be made to last longer by machining them. Machining rotors aids in regaining previously lost friction as well as correcting braking symptoms (described below).
It’s typical to have brake pads and rotors machined at the same time to guarantee that the new pads and rotors make excellent contact. If the servicing are not performed at the same time, the pads and rotors will wear down at different rates.
Is rotor resurfacing also worthwhile? When a rotor is resurfaced, metal is removed, making the rotor thinner and limiting its remaining service life.
As a result, several customers and automakers argue that rotors need not be resurfaced every time the brake pads are replaced (unless the rotors are badly grooved or uneven).
Is it more cost effective to resurface or replace rotors?
Brake Rotors Replacement In certain circumstances, replacing a brake rotor instead of having it resurfaced is less expensive, especially if you are a do-it-yourself technician.
You are better off replacing rather than resurfacing because resurfacing at home may be quite expensive. New rotors are, by chance, quite simple to install.
Should I replace or turn my rotors?
When changing brake pads, resurfacing (also known as “turning” or “cutting”) brake rotors is recommended. Most people will agree, however, that turning at every brake service is excessive for most drivers in most automobiles.
A better rule of thumb is to resurface rotors every other brake replacement.
