Diagnosis And Testing - Disc Brake Rotor: Notes
WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The rotor braking surfaces should not be refinished unless necessary.
Light surface rust and scale can be removed with a lathe equipped with dual sanding discs. The rotor surfaces can be restored by machining with a disc brake lathe if surface scoring and wear are light.
Replace the rotor for the following conditions:
- Severely Scored
- Tapered
- Hard Spots
- Cracked
- Below Minimum Thickness
