Loosen the lug nuts a bit. Put the car up on jack stands. Take off the tires. Take off the brake caliper. Now the rotors should come off. If they are stubburn, hit them with a rubber mallet or 2x4. Collapse the piston on the caliper and replace the pads( lithium grease the slide areas) Put your new rotors on, reinstall the brake caliper, put your tire back on and your done. Re-torque the lug nuts after 25 miles.
