What is The Brake Rotor?

A brake rotor is a kind of round flat piece of steel that fixed to a rod held on the inside of the wheel. You can see brake pads on both sides of the rotor. When you put pressure on the brake pedal, simultaneously the pads compress around the rotor making the speed of your car slow or even stop the car.

The Problems that Brake Rotor Occurs

As the brake rotors do a lot of responsibility to control the speed and the motion of your car, so it is obvious that over time, the metal rotor starts wearing out and becomes thinner. As a result, the rotor will heat up faster. This may create pedal pulsate while applying the brakes. In this situation, the only thing you can do that you have to replace the rotors. But if the situation is not so serious and if you need to keep your rotors safe or remove the rust from the brake to keep it in full working order, then you have to take some preventive action and what better you could do than cleaning the rotors frequently.

When Do You Need to Clean Rotors?

The ways where you need to drive your car everyday is polluted enough to make your brake rotors dirty. Even if you keep your car in the garage for a longer period it also gets dirty equally. This may increase the possibility of building rust on the rotors. If that so, then you have no way left but cleaning the brake rotors regularly. Generally, you always start taking care of the brake rotors after noticing rust on them. Sometimes you make late and end up buying a new one as the condition gets worse.

Try to go as deep as possible to clean the dust of the rotors. Using a brush instead of cloth might be a better idea for this job. Regular cleaning extends the durability, and also helps your rotors perform better.

Braking Away the Rust

Suppose your car is kept idly for a few days and you find the rust build-up happens on the wheels as well as the brake rotors. In this situation, you have to follow this method to remove rust easily. At first, you have to drive your car freely at a low speed (5-10 miles per hour) to some distance and then press the brake continuously. The brake should be sharper than normal driving. It can create harsh friction between the brake pad and rotor and the rust will be removed only to make the rotors clean. You cannot repeat this more than 5-6 times as it may exhaust the rotors.

Using Dishwasher and Scrub

This method is suitable for those who know how to take out the brake rotor. This is one of the best processes to clean the dust that accumulated on the rotor. All you need to take out the rotor and clean the rotor using some dishwasher and scrub. Once the cleaning is done you have to dry the rotor using a piece of dry cloth. But remember, this method is not for removing the rust.

Using WD-40

W-D in WD-40 stands for Water Displacement. This multi-use product is a unique kind of lubricant which contains anti-corrosion agents and ingredients that can easily remove rust from any metal surface. If you find a light build-up of rust on the rotors, then spray some WD-40 over it and leave it for 5-10 hours. After that, wipe the rust away from the rotors using a sandpaper. To get the best result out of that, you need to draw out the rotors and wipe the rust out of the whole surface of it.

Now move the grinder over the rusty parts of the rotor so that the rust is started wearing off. But while using this grinder you should not apply too much pressure as it may eat away the surface making it uneven. When the grinding is done, you’ll certainly get the rust-free, clean brake rotor for your car.

Taking Preventive Measure

As I said earlier, brake rotors cleaning job usually is done after the rotors build rust. But there is a process that you may use while scaling a new rotor set that can prevent the rotors from building rust for an extended period. To make this possible you have to give a coat of brake caliper paint to the middle portion of each rotor. But before that seal off the braking surface with the tape to save it from desecration. Finally, wipe off the residue of tape using a kind of cleaner on a cloth that works better in this case.

Some Necessary Tips

  4. If you find scratches on the rotors while inspecting the job, you should take your car to a service center or try to replace the existing rotors with a new one to avoid any kind of problem while driving the car.
  5. Remove the wheel before you can access the brake rotor. After lifting the car with a jack, use a lug wrench to cut-off the wheel’s lug nuts.
  6. If you have to remove the rotor for better cleaning, disconnect the brake caliper and the mounting bracket from the rotor. Using a hex wrench to pull the rotor right off the studs that come helpful to remove the excessive rust out of the brake rotors.
