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.
Are rusted rotors a problem?
Rust is bad because it weakens rotors over time, and makes the brakes noisy when the vehicle is first driven after being parked. Rusty rotors also increase brake pad wear. Like brake pads, brake rotors don’t last forever; they usually last anywhere from 30,000 to 70,000 miles.
Can wd40 remove rust from rotors?
To do so, ensure you put down a tray to catch any runoff and then spray the rotor with WD-40 Specialist Automotive Brake & Parts Cleaner. If stubborn rust or grime remains, apply more Brake & Parts Cleaner, and use steel wool or a wire brush to work the surface further.
Why do my rotors look rusty?
Why do my rotors rust? This boils down to the material of the rotor. Unless you have an exotic car with carbon-ceramic brakes, then your rotors are most likely made out of cast iron, which is prone to rust. Iron oxidizes easily, and rust will form on the surface of the discs if they are exposed to water or moisture.
Why do my rotors keep rusting?
The rate at which rotors wear depends on several factors, including the quality of the rotors, the types of brake pads being used, how fast the rotors cool down, your driving style, and the amount of exposure your rotors have to moisture and road salt – elements that can create excessive rust and corrosion.
Can you spray WD40 on brake rotors?
Spraying WD40 on your rotor will cause it not to function properly. When you use WD40 on your brake rotor grease, it is left behind. Oil on the rotor could result in your car not stopping when needed. This could lead to car accidents and injuries; especially, if you are unaware of the risk of using WD40 on your rotors.3 days ago.

Can you spray brake cleaner on rotors?
Brake Cleaning Preparation 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. It may be a good idea to cover areas of the car that could be exposed to the brake cleaner before you apply it.
What happens if you don’t clean new rotors?
If the new rotor is simply installed in place without cleaning this rust off, the rotor will not sit completely flush to the hub. Do not use any anti-seize compounds or abrasive material for the cleaning as that may interfere with the fastening performance and thread geometry.
Are rusty rotors safe?
There is a certain thickness that all rotors must be at in order to still be considered safe. Rust on rotors usually isn’t a problem unless it is causing issues with your braking. Most times, a little rust on rotors will only wear brake pads a little differently.
Should new rotors have rust on them?
A: Brake rotors get rusty and there is not much you can do about it. It really does not matter if it is a brand new car or something older. Since it is designed to spray directly on the wheels, it should not affect the brakes and may prevent surface rust on a vehicle not driven.
How long does it take rotors to rust?
Rust can occur in less than 12 hours. The first brake application will shave off the rust. Verify that you have rusty rotors.
Can rusty rotors cause vibration?
Rust and dirt also can build up on a rotor and cause minor vibrations in the vehicle. A rotor’s thickness needs to vary by only a few thousandths of an inch for the driver to feel vibration through the brake pedal or steering wheel. The drums also can wear unevenly and vibrate.
Which is the best rust remover?

Should you use brake cleaner on coated rotors?
New brake rotors are often coated with an anti rust coating at the factory. That coating must be removed to achieve proper braking. You can use spray brake cleaner and a clean rag to dissolve the coating, but don’t stop there.
What do you spray on new rotors?
Manufacturers of rotors tend to put a thin layer of grease on the rotors before shipping them out to prevent rust buildup. This layer should be cleaned off before you install the rotors onto the car. Spray the rotor with brake cleaner and wipe it with a clean rag.
Can you clean brake rotors with alcohol?
When it comes to cleaning disc rotors, the general consensus is to use a specialist product that doesn’t leave any residue, such as isopropyl alcohol. “We recommend a mild soap and water to clean disc brakes. This is to help avoid contamination of the pads and rotor. Brake cleaners and other sprays are unnecessary.
