1. Rotor Inspection: Before making a decision, your mechanic will inspect the rotors for any signs of severe wear, damage, or heat cracks. If the rotors are too thin or have excessive damage, they may need to be replaced.
2. Thickness Check: The mechanic will measure the thickness of the rotors to ensure that they meet the minimum specifications set by the vehicle manufacturer. If the rotors are below the minimum thickness, they will need to be replaced.
3. Turning Process: If the rotors meet the minimum specifications and are in good condition, they can be resurfaced through a process called "turning" or "resurfacing." This process involves removing a small amount of metal from the rotor's surface to correct any imperfections or remove any built-up ridges or grooves.
4. Removal of Rust and Debris: The rotors will be cleaned thoroughly to remove rust, debris, and any contaminants. This ensures a smooth and even braking surface.
5. Final Inspection: Once the turning process is complete, the mechanic will inspect the rotors again to ensure that they are smooth and meet all the necessary safety standards.
6. Brake Pad Replacement: Typically, when rotors are resurfaced, the brake pads will need to be replaced as well to ensure optimal braking performance and prevent uneven wear.
It's important to note that turning rotors is not always possible or recommended. If the rotors are severely damaged, they may need to be replaced. Additionally, turning rotors can reduce their overall lifespan, and they may potentially need to be replaced sooner than if they hadn't been turned.
To determine the best course of action for your rotors, consult with a professional mechanic who can inspect them and provide you with an accurate recommendation based on their condition.
