Brake Rotor Scrap Value: Cast Iron Rates, Weights and When Not to Scrap

Brake rotors pay about $0.09 to $0.17 per pound as of 21 August 2026, which works out to roughly $3 to $6 for a typical 30–pound rotor. A full set of four off a pickup, around 120 pounds of iron, brings $11 to $20 total. Rotors are the definition of a low–value, high–weight item: heavy to haul, cheap to sell, and almost never worth a special trip on their own.

The per–pound number, and why sources disagree

Published rotor rates differ by nearly two to one right now. That is not a rounding error, and you should know about it before you accept the first offer.

Two things drive the spread. First, some yards grade rotors as their own premium automotive cast iron line and some just throw them in with heavy cast. Second, ton definitions vary. A gross ton is 2,240 pounds, a short ton is 2,000. Rockaway states gross ton explicitly. Others do not always say. Always ask which ton the yard means.

Some real local quotes iScrap logged this year: $305 per ton in Shelbyville, Michigan on 11 August 2026, $0.13 per pound in Kankakee, Illinois on 27 June 2026, and $0.14 per pound in Akron, Ohio on 14 May 2026. That is the realistic middle of the range.

Context on volatility: Scrap Monitor shows a 52–week band of $90 to $470 per ton on automotive cast iron, and a 30–day move of minus 7.8 percent. This grade swings hard.

What a rotor weighs, and what that actually pays

Weight is the only variable you control. Here is the arithmetic, using $0.09 per pound at the low end and $0.17 at the high end.

Weights are from an Engineer Fix breakdown of typical rotor masses. Note the last line. Four rotors off a half–ton pickup is a two–man lift for the price of lunch.

The minimum weight problem

Rockaway Recycling requires a 500 pound minimum on all steel and iron purchases. At 30 pounds a rotor that is roughly seventeen passenger–car rotors before the yard will even weigh you in. A shop clearing a month of brake jobs hits that easily. A homeowner with one brake job does not.

That is why rotors usually land on the general iron pile instead of selling as a graded lot. Unless you move volume, the premium automotive cast iron rate is not available to you.

Why the value is so low

Rotors are gray cast iron, one of the cheapest commodity metals in the yard. No copper, no aluminum, no precious metal — nothing that carries a premium.

Look at where iron sits against the rest of the ferrous board on 20 August 2026, per Scrap Monitor:

• Automotive cast iron, rotors and drums: $336–$381 per ton
• Plate and structural steel: $246–$314 per ton
• Light iron and shredder: $202–$291 per ton, about $0.10–$0.13 per pound
• Number 1 prepared steel, HMS: $202–$246 per ton, about $0.09–$0.11 per pound
• Heavy cast iron: $179–$224 per ton
• Steel turnings: $90–$112 per ton

Rotors do sit at the top of that list, which surprises people. The problem is not the rate. It is that iron rates are measured in cents while the item weighs 30 pounds. For comparison, Steel Market Update reported busheling at $457.50 per gross ton in August 2026.

Scrap Monitor also notes the yard price on automotive cast iron sits about 270 percent above the CME world benchmark of $97 per ton. That spread is the yard covering handling, freight and sorting on a heavy, awkward, low–value product.

The two exceptions worth checking

Aluminum hat rotors

Two–piece rotors replace the center hat with aluminum to cut unsprung weight. If you have these, separate the hat from the iron ring. Cast aluminum ran $0.65 to $0.83 per pound, averaging $0.72, on 20 August 2026 per Scrap Monitor. That is roughly seven times the iron rate.

Be realistic. A hat is only a few pounds, so you are turning about $0.30 of iron into $2 to $3 of aluminum per rotor. Worth doing on a stack. Not worth an hour with a cutoff wheel for one.

Also note: if you leave mixed material attached, you lose. Rockaway warns that items with ceramic or plastic attached may be downgraded.

Carbon ceramic rotors

Do not scrap these. Carbon ceramic discs have no ferrous value and no yard will pay a premium. What they have is enormous replacement cost.

Figures from a 2026 StopFlex cost guide:

• Single OEM performance–car carbon ceramic rotor: about $5,000
• Single Lamborghini Huracan rotor: about $6,700
• Ferrari 488, per axle: $7,000–$10,000
• OEM full–car replacement, performance car: $20,000–$35,000
• Aftermarket continuous–fiber set: $6,000–$13,500

A carbon ceramic rotor with life left in it is a used part worth hundreds or thousands to the right buyer. The same guide notes that carbon ceramic cannot be machined back the way steel can, so serviceable used discs carry real demand. Identify them by weight — Engineer Fix cites 40 to 60 percent lighter than iron, with an example of a 33 pound iron rotor against a 16 pound ceramic equivalent — and by the gray, speckled friction face rather than a rusted one.

Does resurfacing or resale beat scrapping

The answer for ordinary iron rotors is blunt. Resurfacing no longer makes economic sense on most passenger vehicles. A new budget rotor costs $18 to $30. Turning the old one costs $25 to $45 and leaves you with a thinner disc that runs hotter and warps sooner. The gap has closed to the point where replacement usually wins.

That means the used rotor has no resale path. It goes in the iron pile.

The exceptions are worth naming:

• Heavy–duty and commercial rotors. At 57 to 71 pounds and much higher new cost, turning can still pay.
• Rare or discontinued applications. If no new rotor exists, resurfacing is the only option and the used disc has value.
• Carbon ceramic. Always sell, never scrap.
• Nearly new rotors off a wrecked vehicle. A low–mileage set sells used for far more than $20.

Yard prep that protects your rate

• Rotors must be dry and free of oils, fluids and grease. Contaminated iron gets downgraded or rejected.
• Separate rotors from drums, calipers, hardware and backing plates. Mixed loads grade to the worst material present.
• Pull off any bolted–on aluminum hats and sell them separately.
• Remove pads, clips and any plastic or ceramic attachments.
• Accumulate to the yard minimum. Below 500 pounds you may not get a graded rate at all.
• Ask whether the quote is per gross ton or short ton. That alone is 12 percent.
• Ask whether the yard has a separate rotors and drums grade. Many do not, and that alone is the difference between $0.09 and $0.16.

Ferrous prices move weekly and vary by region and yard. Every figure above is a published guideline from the date shown, not an offer. Call your local yard for a live number before you load the truck.
