Stop Driving This issue may require immediate attention.

Scraping Sound from the Wheel Area

A persistent scraping sound coming from a wheel area -- one that does not necessarily require braking to occur -- typically indicates the metal backing plate of a completely depleted brake pad dragging directly on the rotor surface. It can also mean road debris has been caught inside the brake dust shield. Either way, it warrants immediate inspection.

What Causes This Sound?

• Brake pad worn completely through, with the metal backing plate now contacting the rotor
• A stone or road debris wedged between the brake pad and rotor or inside the dust shield
• A bent brake dust shield rubbing against the rotor after an impact
• A seized brake caliper piston holding the pad in constant contact with the rotor
• ABS reluctor wheel debris caught between the rotor hat and bearing shield

Not Safe to Drive

A brake pad worn to bare metal can destroy a rotor in a single trip and severely degrade braking ability. Stop driving and have the brake system inspected immediately.

Complete pad wear causing scraping is common on F-150 trucks with heavier towing loads, Silverado work trucks driven on rough terrain, and high-mileage Camrys that have had brake service deferred.

Estimated repair cost: $200–$500 per axle for pads and rotors; add $150–$300 if caliper replacement is needed

Frequently Asked Questions

What if the scraping only happens sometimes?

Intermittent scraping often means debris is only contacting the rotor at certain wheel positions. Even so, have it checked -- a bent dust shield or trapped stone should be removed promptly.

Can I bend the dust shield back myself?

If you can confirm the dust shield is the cause and it is simply bent, careful bending with pliers is possible. But if you cannot confirm the source, have a shop inspect it before driving further.

How fast will a metal backing plate destroy a rotor?

Faster than most people expect. A rotor can develop deep grooves and heat-induced warping within a single commute. What started as a $150 pad job becomes a $400 pad-and-rotor replacement.
