Replacing a rotor on a 4×4 Dodge is something you can do when you change the brake pads. Reasons why you would need to change the rotors include warping, grooves from bad brake pads, cracking, or they may just be too thin. It does not take long to replace the rotors. You can expect each wheel to take about 30 minutes to complete, and you can do the job in your driveway.
Loosen the caliper bolts with the socket and ratchet. Pull the caliper from the mounting bracket. Secure the caliper to the strut using a wire tie. Remove the retaining clips from the wheel lugs using the pliers. Pull the rotor away from the wheel assembly.
