Update: So I figured out my left side caliper was hanging up. It smoked a pad and my rotor. I replaced both calipers, pads, and rotors. Brakes work awesome, but now I do have an abs light and a brake light on. I hooked up the genisys scanner and pulled a datastream while driving. The left wheel speed never changes, the right and rear speed corresponds roughly with the speedo. I know where the speed sensor is, I'll have to remove the caliper/rotor to get to the little bstard and it's allen key bolt. It's pretty friggin rusty there on top of the hub. I can blow/scrape it off as best I can, but is there anything I should worry about when I remove the old one? What I mean is, if anything, say RUST, should fall down the little hole there, is there anything to worry about? Part won't be in til Monday anyway.
