I purchased a 1998 Ford Expedition that sat in the auction yard for a year before I acquired it. Redid alot of front end work and brake work (I do this to any used vehicle I purchase) I tried a 20 lb maul to remove rotors, did not work. I ended up cutting out a large piece of the rotor with a grinder and using a large pry bar to crack the rotor and they both came off!!
