These hard spots yield uneven wear across the brake disc. Trying to shave them off by resurfacing will not cure the problem because hard spots extend below the surface, the only fix is rotor replacement. ... Resurfacing restores a flat and even surface that minimizes vibrations and allows for maximum brake pad friction.

Is it better to resurface or replace rotors?

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 bad rotors cause vibration?

Problem 1: Warped Brake Rotors

When your brake pads are pressing against a warped rotor, this will cause shaking or vibrations to run through your vehicle. Beyond just the inconvenience of shaking, this can raise safety concerns and create trouble for your brakes.

When should rotors be resurfaced?

Sometimes your rotors may need to be resurfaced because they have worn unevenly, warped from heat, or become damaged by worn brake pads or pitted from corrosion or rust. Resurfacing rotors removes some of their metal, until the surface is smooth and even again.

Is it cheaper to resurface or replace rotors?

Cost: It is sometimes cheaper to replace the rotor than to resurface the rotor. You can get after-market brake rotors for a fairly low price, making it more cost-effective than either spending time doing the labor of resurfacing yourself or hiring and paying someone else to resurface your rotors.

What Causes Brake Shuddering, Shaking, and Pulsing on My Car or Truck?

When should you not resurface rotors?

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 resurfacing rotors cost?

RepairPal.com, according to its quotes from mechanics across the United States, noted the average price could average between $235 and $329, with labor costs estimated to be $158 and $200, while parts are priced between $77 and $129.

Can you resurface your own rotors?

Take the brake rotor to a local machine shop to have it turned. Rotors cannot be turned by an amateur, since the process requires special equipment and special skills to be done properly. The machine shop will be able to look up the minimum thickness of your brake rotor to determine if it is still usable.

Does O'Reilly resurface rotors?

Drum & Rotor Resurfacing

Most O'Reilly Auto Parts locations can resurface your vehicle's drums and rotors if they measure within specs and aren't showing signs of extreme wear. ... Please contact your local O'Reilly Auto Parts store for pricing and availability on drum and rotor resurfacing.

Why do rotors get grooves?

Over time, grooves will naturally develop on the rotor from repeated contact with the brake pads. But these marks take away from the part's capacity to slow the vehicle, as well as cause vibration and pulsation that can be felt in the brake pedal.

Why does my car vibrate at high speeds?

Tires are one of the causes of cars vibrate when driven at high speeds. Tires do have a significant role in a vehicle, be it four wheels or two wheels. ... Vibrations in the car can also be caused by the tires' unbalanced position, such as car tires that are too small or not up to standard.

Why does my car vibrate at 40 mph?

Typically vibration (shakes) are due to something that is out-of-balance. Given the tires and wheels have been balanced, it could be a wheel bearing vibration, as a worn, loose, or bad wheel bearing could cause shaking. It could also explain the noise getting louder as you accelerate.

What happens if you don't resurface rotors?

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.

Do I need an alignment after replacing rotors?

Hello - a front-end alignment is neither required or useful after replacing a brake rotor. Replacing the rotor will not enhance, or detract from, your existing wheel alignment.

Are premium rotors worth it?

Premium pads can have an increase in stopping power and a decrease in brake fade. ... Some drivers may be able to notice a better “brake feel” when using high-end pads and rotors as the braking experience may seem smoother and more precise.

Does Walmart do brakes and rotors?

Even though you can't get your brakes serviced at the Walmart Auto Center, you can purchase the parts you may need for your repair in the Walmart store. Walmart sells everything from brake pads, brake rotors, and brake calipers in their stores.

How much does Midas charge for a brake job?

Midas: Midas charges roughly $80 per hour for labor costs when working on brakes. They charge about $50 for a brake drum package, $60 to replace brake fluid, and upwards of $800 for a complete caliper and rotor job.

Are my rotors warped?

If you notice your steering wheel or brake pedal wobble when you apply the brakes to slow down or stop, chances are your rotors are warped. If the warp isn't too bad, you might not really notice the shaking. If the warp is serious, you'll definitely feel the vibration.

What will a warped rotor do?

Rotors are normally flat and smooth, and as the brake pads clamp down on them, your wheels stop. When they're warped… Your brake pads can't clamp your rotor as easily. That's why you'll feel a shudder on the brake pedal when you try to stop, especially at high speeds when your rotors are rotating faster.

How much does turning rotors cost?

The cost for turning a rotor runs anywhere from $15 to $25 per rotor. Purchasing new rotors typically will cost from $20-$30 per rotor and of course you will have a lot less problemsand a much longer rotor and brake pad life span.

Why is my car shaking when I brake?

If you feel the shaking or vibration in your steering wheel and your brake pedal, it could be your rotors. The rotors get pressed by the brake pad to help slow your vehicle down, and if the rotors are out of balance, this could be causing the vibrating tremors that you feel in the pedal and steering wheel.

Is machining rotors necessary?

New rotors are machined to specifications and are ready to install out of the box. No further resurfacing is necessary. Turning new rotors reduces their thickness and shortens their service life – and may create runout problems that were not there before you turned them!

How much does machining rotors take off?

Cutting a rotor in one pass is essential for productivity. For non-composite rotors, it is possible to take as much as 0.020″ per side while still having an acceptable finish. However, with a composite rotor or one with hard spots, the depth should be reduced, likely below 0.010″ per side, for a quality finish.
