Brake discs

- Hyundai can be a real tough egg to crack. Get yourself a BIG hammer or rubber mallet. The front rotors are a lot harder to remove that are the rear. Not certain which ones you are having difficulty with. With the rear rotors (once the tire and brake hardware is ALL removed) sit facing the rotor. Make certain the car is securely mounted on jack stands (and not just on the jack itself). Hit the top edge of the rotor hard with the BIG hammer. Rotate the rotor one-quarter turn, hit the top edge again real hard. The rear rotors should break the corrosing seal after 1 to 3 hits.

With the front rotors you will need to elevate the car and securely mount it on a solid set of jack stands. Crawl underneath the front of the car with your BIG hammer (a 2-3 pound baby sledge works best). Hit the botton edge of the rotor from underneath the car. Rotate the rotor aone-quarter turn and hit it again. Rotate another quarter turn and hit it again. Repeat this procedure until you finally get the rotor to wiggle off. There a flat surface between the hub assembly and the inner rotor that builds up some corrosion, and the hammer is being used to slide these two surfaces apart.

With the rear rotors another trick is to use a propane torch to heat the metal surfaces where the inner ring of the rotor contacts the hub assembly. Once heated use the same procedures as above to break the corrosion ring that has formed. Can't really use the torch on the front rotors because of the very large common surface area. Just be patient and hit hard, it will eventually show signs of coming off.

- Hyundai has a really bad design on some of the brake rotors. Once you remove the tires and the caliper (including caliper bracket) you will need to crawl beneath the vehicle (making certain that it's elevated securly. With a large hammer (baby sledge or rubber mallet) bang on the rotor as you slowly rotate the rotor around in a circle. There's a corrosion ring that forms between the rotor and axle hub that makes it seem impossible to get the rotor off. Once you see some movement in the rotor continue in the same manner. the front wheel rotors are considerable more difficult that the rear wheels. With the rear wheels you can usually break the corrosion ring by banging hard on the top of the rotor from the outside of the wheel well. Hit it hard, rotate the wheel a quarter turn and hit it again.

- On earlier Hyundai's, the rotor is bolted to the hub. You have to remove the knuckle and press off the hub bearing to access 4 mounting bolts (I believe they're 14mm bolts) to detach the rotors from the hubs... then press the bearings back on after you've intalled the new rotors. If you're only resurfacing/remachining the rotors, it's easier to use an on-vehicle brake lathe.

- The knuckle needs to be removed and the hub pressed out using a hydraulic press. Then you can access the fasteners behind the rotors to remove them. Then you need to reinstall the hub and reinstall it and the knuckle on the auto.
