The Hyundai Elantra has two brake rotors: one for each front brake. The rear wheels have brake drums, which produce 20 percent of the Elantra's braking power. Because the Elantra's front disc brake rotors carry 80 percent of the car's braking power, they wear out twice as fast as the rear drum brakes.
Park the car on level ground and turn off its ignition. Open and secure the Elantra's hood. Loosen the lug nuts on the front wheel that has the rotor to be replaced, using the tire iron. Turn the lug nuts counterclockwise.
Place a jack under the frame directly behind the wheel. Raise the Elantra with the jack until you can place a jack stand under the frame. Lower the Elantra with the jack onto the jack stand.
Remove the lug nuts from the wheel and remove the wheel from the wheel hub.
Locate the two bolts on the backside of the brake caliper. The caliper secures over the top of the rotor and holds the brake pads. Remove the bolts, using a socket and ratchet, and pull the caliper off the rotor.
Place a wire tie through the vent hole on the top of the caliper and hang the caliper off the Elantra's strut coil, which prevents the caliper from hanging on the rubber brake line.
Pry the silver cap off the wheel hub, located in the center of the rotor, to expose the hub, using a small flat-head screwdriver.
Remove the bolt located in the center of the hub, using a socket and ratchet.
Pull the rotor off the wheel hub.
