Removing a rusty rotor can be a hard task. When all else fails there are two options - you can choose to break the rotor off the axle stub, or use what is called a puller. Pullers are the best choice for removing rotors. You may have a rotor that can be preserved.

Pullers come in various sizes, and have arms to pull the rotors off the axle. There is a center bolt that pushes against a part of the vehicle that is stationary. The puller distributes force evenly to the arms from the center bolts, which makes the rotor easier to remove. Pulls are a very common method of removing rotors. A three-arm puller often needs to be used. Because pullers are expensive, it is advised to rent instead of buy.

Removing a rotor using a puller can be dangerous. You should know all the risks and safety procedures before using a puller on rotors. They are very convenient and are a great piece of equipment, but they have their risks like everything else. If you are uncertain about performing any kind of repair or maintenance on your vehicle, seek help from a professional mechanic.

Slipping can occur while using a puller if rotors break while being removed. Metal pieces can fly off and cause a hazard. If a rotor breaks while using a puller, it can fall away from the vehicle. Never take of a rotor using a puller without wearing safety glasses first. Never place yourself right under the puller. Keep everyone away when tension is being applied with the puller.

As mentioned above, a three-armed puller should be used to remove rotors. This will require an assistant. The assistant will hold the puller in position as you tighten the puller. The assistant should wear safety glasses, and then stand back when the tension of the puller can hold on its own.

Puller arms will hook at the back of the rotor. The bolt will rest on the axle. If the arms will rest on the rotor, there should be a protection between the surfaces such as wood or cardboard. Once there is enough tension that the puller will hold itself, any people around should move a safe distance.

You want to turn the puller bolt slowly. This will apply pressure gradually. Be aware that any rotor can break during this process. Most of the force is being placed on the outside of the rotor Rust is usually holding it tight to the axle in the center.

The force of the puller may crack rotors as they are being pulled off. This does not mean that you have made a mistake. When a rotor is very severely rusted, they often cannot be removed intact no matter how careful you are. It is not about your technique being incorrect.

Although using a puller is not always successful, it is your best bet when trying to get rusted rotors off of an axle without harming them. The only other way is to bust them off. You may end up busting them with a puller, but at least a rotor may have a chance.
