Published Jan 08, 2026

Rotors can be turned only about 1 or 2 millimeters before they become too thin for safe use and will have to be discarded and replaced. Brake rotors that have been repeatedly over heated may warp and create a vibration in the wheel. This warping will significantly wear out your tires and suspension systems.

How often should rotors be turned?

Typically you want to have your rotors turned every other brake change. This ensures that they remain free of debris and do not warp. Regular brake wear and hot spots can often cause your rotors to become warped and having them turned will ensure that they last as long as possible before having to be replaced.

How long do rotors last after being turned?

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.

Should I turn my rotors or replace them?

Those severely damaged rotors usually need to be replaced, not resurfaced. Some vehicle manufacturers even require that you replace your rotors rather than resurface them. Otherwise, most industry experts suggest that you should replace them every 30-70K miles.

Can you resurface all rotors?

Can resurfacing fix all rotor surface imperfections? No. Rotors resurfacing won't resolve hard spots that come in the cast rotor, as these usually extend well below the rotor surface.

Are rotor resurfacing worth it?

In the long run, it's likely less expensive to replace your rotors when there are consistencies in the face of the rotor. New rotors won't wear as quickly on your brake pads as damaged rotors, and resurfacing the rotors means you'll only get one last "hoorah" out of them before they need to be replaced anyway.

Does O'Reilly turn rotors?

Most O'Reilly Auto Parts locations can resurface your vehicle's drum and rotors if they measure within spec and aren't showing signs of extreme wear. Surface finish is crucial to proper vehicle braking and pad life and should always be part of a complete brake job.

Do mechanics still turn rotors?

Your rotors can be turned (rotated), machines and still be within factory guidelines, but this usually leaves them thin whereby leaving them to warp or vibrate. The cost for turning a rotor runs anywhere from $15 to $25 per rotor.

How much does it cost to turn rotors at AutoZone?

How Much Does It Cost To Turn Rotors At AutoZone? AutoZone can charge up to $25 per rotor for this service but often suggest a total replacement citing cost-effectiveness.

How do you tell if your rotors can be turned?

If your brake rotors have sufficient metal remaining with no hard spots, cracks, severe grooving or rusting, then the rotors could be resurfaced. Some have the opinion that unless the brake rotors have surface issues needing to be fixed, the rotors should not be resurfaced every time the pads are replaced.

How much does it cost to resurface your rotors?

Resurfacing cost per rotor can vary widely. If you remove your rotors yourself and take them to a shop or parts store for resurfacing, the cost can range from as little as $15 to over $45 per rotor. To have a repair shop remove, resurface and reinstall your rotors can cost up to $100 per wheel, $400 for the whole car.

Should brake rotors be smooth?

Over time, your rotors will also wear down and you may find the pads have created a slight groove in the rotor. This is very harmful to the rotor and this must be avoided. A healthy brake rotor will be a smooth and uninterrupted surface, free of dust, grooves and grit.

Can you resurface rotors with hot spots?

See our Brake Rotor Bedding Guide. If this is caught early on, you can possibly remedy it by bedding in your brakes with a more abrasive pad, or resurfacing your rotors. If the heat spots are extensive, you will need to replace your rotors.

How long does it take to change all 4 brakes and rotors?

Answer provided by. Well, the good news is that fixing your car's brakes and rotors should only take between 30 minutes and an hour.

Can warped rotors be turned?

What can you do if you have warped rotors? You have two choices: replace them, or machine them. Warped rotors, if they're thick enough, can be turned in a machining process that uses a lathe to smooth the rotor. Unfortunately, since it's a stressed metal, your rotor can return to its old, warped shape.

What happens if you don't turn rotors?

If you don't replace the rotors when needed, you risk brake failure and an accident. The rotor absorbs and dissipates heat when the brakes are applied. The thinner the rotor becomes, the more heat is absorbed. This excess heat warps the rotor.

Do I need to turn my rotors?

The quick and easy answer to the question is "no." However, this answer is relative to the reason why the pads are being replaced. If the disc brake system has been functioning properly and the pads are being replaced due to wear, you might forgo turning the rotors.

Can you replace one rotor?

Yes , you can install just one disk/rotor without the other. BUT, the brake pads should ALWAYS be replaced on BOTH sides, AT THE SAME TIME. If you only replace pads on that one side with the new rotor, then you will run into the same problem later on, but on the other side.

Can you sandblast rotors?

Its going to be hard to use a sandblaster and not damage the rotor surface. Just get a wire brush or some low grit sandpaper to get rid of the rust.

Is it OK to just change brake pads?

Yes, but it depends on the condition of your brake rotors. If they aren't damaged or thinned beyond the discard thickness, you can definitely change just the worn brake pads.

What is a warped rotor?

There is a lot of heat that the brake rotors withstand in the process of braking; the need to dissolve the heat in a quick manner is there so the brake pads can be pressed down again. The surface of the brake rotors can become uneven over time all due to the mass amount of heat… this is also known as warping.

How long does resurfacing rotors take?

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.

Do you have to replace both rotors at the same time?

Whether you're replacing both your brake pads and rotors or just replacing one part, you still have to replace them on both sides of the axle. For example, even if just one rotor is worn out and the other one is in good condition, you still have to replace both rotors.

What is the grinding noise when I brake?

If your brakes emit a sharp grinding sound while braking, it's likely that the brake disc and the caliper are rubbing together. The sound is usually heard when you stop your car, but you may also feel the brake pedal rumble as you step on it.

Why are my rotors scraping?

If your brake pads are excessively worn, the metal backing on them can become exposed, allowing the rotors and metal to grind against each other when you brake. Not only does this cause an unpleasant sound, but it can also damage your rotor, reduce your brakes' responsiveness, and lead to brake failure.
