- In most cases, it’s not recommended to resurface brake rotors and it’s better to replace them.
- Resurfacing will result in less material on the brake rotors which will increase the temperature.
- Most car manufacturers do not recommend resurfacing the brake rotors.
Subsequently, How long do resurfaced rotors last? Typically, brake rotors last between 30,000–70,000 miles. But you should bring your car to a licensed mechanic for regular brake inspections and pay attention to your vehicle to know when you might be due for brake service.
What happens if I don’t resurface my rotors? There is no need to resurface them as this may actually produce runout and will reduce their service life. If your vehicle originally included brake rotors with a separate hub and disc (composite rotors) they can safely be replaced with cast iron brake rotors.
Yet, How long does it take to resurface rotors? You can take them into many auto parts stores and get them turned for about $15/ea and it should take about 15-20 min./ea. You can take them into many auto parts stores and get them turned for about $15/ea and it should take about 15-20 min./ea.
How can I resurface my rotors at home? 
How long does it take to resurface 4 rotors?
You can take them into many auto parts stores and get them turned for about $15/ea and it should take about 15-20 min./ea. that’s what i paid, although i had to leave my rotors with the guy cause he was busy when i walked in. i picked em up like 2 hours later.
How do you tell if your rotors need resurfacing?
A resurfaced rotor must meet the minimum thickness specification defined by the rotor manufacturer. If a rotor can’t meet the minimum thickness, you shouldn’t resurface it as it’ll become too thin, unsafe, and warp easily. Next, the rotor mustn’t be warped or cracked. Always get a new rotor for this type of damage.
How often do rotors need to be resurfaced?
Even resurfaced rotors need to be replaced every 70,000 miles, doesn’t matter that they are in good working condition. Look for signs of uneven wear, excessive runout, and heavy pitting, spotting, grooving, hard spots, or cracking.
How do you tell if rotors need replacing?
Additionally, brake rotors may also need replacement when any of the following signs appear:
- After pressing the brake pedal, the driver feels a vibration in the steering wheel and/or the brake pedal. Cause: Pad Deposits. …
- The brakes produce very loud noises when braking. …
- The brake rotor has developed surface cracks.
Is rotor resurfacing bad?
A resurfaced rotor must meet the minimum thickness specification defined by the rotor manufacturer. If a rotor can’t meet the minimum thickness, you shouldn’t resurface it as it’ll become too thin, unsafe, and warp easily. Next, the rotor mustn’t be warped or cracked.

Is it bad to resurface rotors?

Always get a new rotor for this type of damage.
Will new brake pads smooth out rotors?
If there is enough thickness left in your rotors when you go to have your brake pads replaced, some shops will offer to resurface your rotors on a machine (called a lathe) to bring them down to a smooth surface for the new brake pads to wear against.
What happens if my rotors are scratched?
As Your Mechanic and Car and Driver explain, brake rotors are eventually worn away over time. Once they get too thin, it’s time for a replacement. But, if the rotors have severe scratching and scarring, or there’s a noticeably raised outer-lip on the rotors, that’s a symptom of warping.
