Why are my rotors turning black?

It can happen when the pad and or rotor overheat and essentially burn. Don't sand it off. Just leave it there and ride it, and it should go away.

Why are some brake discs black?

After machining and runout inspection BSD discs are black thermic coated against corrosion. Thermic black coating has the highest corrosion resistance and used by all car builders ( they use silver we prefer black) Sold and priced in axle sets front or rear.

Can rotors be black?

If you want black rotors have them powder coated for a long lasting good look. the rotor face will always go back to bare metal unless you go to a ZR-1 carbon brake assembly. You can also spray paint them wit ceramic black caliper paint. Either way they will need to be removed from the car.

Why do my rotors look burnt?

Heat spots on brake rotors occur when brakes aren't broken in (bedded) properly and the brake pad deposits on the rotor accumulate and eventually turn into a compound known as cementite. You don't want Cementite on your brake rotors.

How do you remove oxidation from brake rotors?

Use Brake Cleaner to Remove Rust From the Rotors

Let the rotor dry, then wipe it with a clean rag (no oil on the rag). If some rust remains, apply more brake cleaner and work the surface with steel wool or a wire brush. Wipe off the rotor and finish with a final shot of cleaner.

Rusty Rotors: What Causes Rust Jacking on Rotor Inboard Only?

How much does it cost to get your rotors cleaned?

You can typically get your brake rotors resurfaced for around $25 each. If the shop is already performing a brake pad replacement, this might be included with the service. If you are doing your own brake pad replacement, you will need to remove the rotors and take them to your local shop.

How long should rotors last?

As a general rule, you should get your brake pads replaced every 10,000 to 20,000 miles to keep wear to a minimum. When it comes to your rotors, you have a bit longer. Your rotors should be replaced between 50,000 and 70,000 miles to keep your brakes in peak health.

How can you tell if rotors are bad?

How can you tell if rotors need to be replaced?

Will black brake rotors stay black?

They will stay black (or relatively black) for about the first 100 miles... Yeah they come off pretty quickly. It doesn't look so great once the paint or coating comes off.

Is it safe to use brake cleaner on rotors?

The cleaner can be used on brake linings, brake shoes, drums, rotors, caliper units, pads and other areas of the braking mechanism while they're still intact.

Should you paint rotors?

When looking for paint to use on your calipers and/or rotors, get only high-temperature paint. Be sure to get paint that can withstand at least 500 degrees F. Brake calipers and rotors can get hotter than the engine. So these parts need paint that can withstand the high temperatures.

Are discolored rotors bad?

If the rotors appear to have grooves in the surface or a blue discoloration (caused by heat), it's likely time to replace them. Other signs that your rotors are bad will reveal themselves while you drive your vehicle.

What does black brake dust mean?

The black dust that accumulates on your wheels is what remains of your pads, which is a natural part of this process. Excessive brake dust may not be a result of normal wear and tear, however.

What is the black stuff on my wheels?

Basically, brake dust is made up of iron particles and is caused by the grinding of the cast iron brake rotor by the brake pads. Additionally, brake dust contains some of metallic elements of the brake pad and carbon residue, which also comes from the brake pad.

What are signs of a bad brake caliper?

Can I just replace front rotors?

Rotors can usually only be resurfaced once, if at all, before they must be replaced. Ultimately, resurfacing rotors when you install new brake pads is a middle price point and a good compromise if you don't want to spend more money on new rotors.

How much does it cost to replace a rotor?

Rotors cost between $30 and $75 each. Labor to replace rotors and pads is around $150 to $200 per axle. Brake pads and rotors come out to around $250 to $500 per axle.

Is it cheaper to resurface or replace rotors?

Resurfacing these rotors with an on-car lathe can virtually eliminate runout problems, but it requires investing in the equipment. Some installers tell us it's cheaper and easier just to replace the rotors.

Should I replace all 4 rotors?

You do not need to replace all 4 rotors at the same time, but it is recommended to replace the rotors and pads as a set for each axle front or back at the same time. If the front brakes need to be replaced but the rear brakes are not worn out yet, then you do not need to replace the rear brakes.

How often should rotors be resurfaced?

Even resurfaced rotors need to be replaced every 70,000 miles, doesn't matter that they are in good working condition. Look for signs of uneven wear, excessive runout, and heavy pitting, spotting, grooving, hard spots, or cracking.

How much does it cost to resurface 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.
