How Do I Diagnose and Fix Wheel Scraping Noises I Hear While Driving?

Inspect Your Rotor, Brake Pads, and Dust Shield 

Tools used:
  • Flat blade screwdriver

What Is a Dust Shield, and What Does It Do?

A dust shield is responsible for keeping debris, such as rocks or water, from contacting or getting trapped on your rotor. It’s especially helpful in areas and climates where vehicles are prone to rust. For example, the dust shield minimizes large splashes of water that could contact your rotor so it won’t rust as quickly.

Follow these steps to inspect your brakes

  1. Raise the Vehicle Off the Ground

    Safely raise your vehicle off the ground with a jack and jack stands so you can inspect the area where the scraping noise is coming from.

  2. Inspect the Brakes for Wear

    Inspect your brake rotor or pads in this area for any noticeable signs of wear or damage.

  3. Locate the Dust Shield

    Find your dust shield behind the rotor, which looks like a thin piece of sheet metal.

  4. Inspect the Wheel Bearings

    Check your wheel bearings for any play, which may cause your rotor to shift and contact the dust shield. In this case, the scraping noise may be more apparent when you’re turning. You may also notice that your rotor’s edge has rusted unevenly because of that play.

  5. Inspect the Brake Pads’ thickness

    Inspect your brake pads’ thickness. Typically, brake pads are 8 to 10 millimeters thick. If you think the pads are too worn, you may need or want to replace them, along with your rotor.

  6. See If Your Brakes Need to Be Replaced and Pry the Dust Shield Away

    If you find that your brake pads and rotor look like they don’t need to be replaced yet, you can instead gently pry the dust shield away from the rotor with a flat blade screwdriver. That will prevent it from contacting the rotor until you do replace your brake pads and rotor.

  7. Test Drive and See If the Scraping Noise Has Stopped

    After gently prying the dust shield away from the rotor, go for a test drive to find out if the scraping noise has stopped. If it hasn’t, you’ll probably need to replace your rotor and pads.

How Much Will This Repair Cost?

Dust shields and backing plates can range in price from around $30 for a single part to over $150 for a kit.

Depending on the vehicle, wheel bearing and hub assemblies can cost from as low as $20-$30 to over $500 for a pair.

As with hubs and bearings, depending on the vehicle brake parts could cost from as low as $20 to over $100.

Add on the average price of a mechanic and the repair can easily cost over $100.

  1. My car makes a metal on metal sound when driving at high or low speeds. Sounds like front wheel are but hard to be certain. It comes and goes and pressing the brakes doesnt cause it or make it go away. All the brake components: pads, rotors, parking brake have been changed. In hopes that was the issue as my mechanic could not find what the cause was. It didn’t do it for 2 weeks after I got the vehicle back but is happening again.
