Thanks all for helping me out with this problem. Come to find out, there was rust behind one of the holes in the rotor, which of course meant the rotor wouldn't go in straight. New rotor, $26.00, Brake job (grand total for new left rotor, pads, pad quieter, caliper grease: $55.00). The fact that I'll never have to go to Midas for new brakes, Priceless. (Saved $190.00)
