The brake disc, also known as the rotor, is part of the vehicle's safety system and requires proper care so your vehicle will operate properly. Occasionally, the brake disc can become warped or scratched, causing the brake pads to wear unevenly and preventing the vehicle from stopping safely. Removing the brake disc is a job that can be done in about a half hour, allowing you to replace the damaged disc. You can remove the brake disc yourself, saving you time and money.
Drive the vehicle onto a level surface and put it in "park." Set the emergency brake and place a wood block behind one of the rear tires.
Loosen the lug nuts of the tire you are removing with a tire tool a couple of turns. Raise the vehicle up with a floor jack and slide a jack stand under the axle near the tire to be removed.
Lower the vehicle down so it is resting on the jack stand and move the floor jack out of the way. Take the tire off the vehicle, using the tire tool to remove the lug nuts and set the tire and lug nuts out of the way.
Remove the brake caliper from the rotor, using a socket wrench to loosen the bolts that are securing the brake caliper. Slide the bolts out of the caliper and take the brake pads off the caliper by hand.
Suspend the brake caliper from the vehicle frame with a wire hanger. Rock the rotor back and forth gently until you can slide it off the hub by hand.
Always set the vehicle emergency brake before attempting to remove the brake disc.
