In this "tutorial" on how to resurface a brake rotor with a grinding wheel (already a bad idea at best, don't do that), our hero realizes the real cause of his problem was human error.When he got finished removing a brake pad, he sheepishly admits that he had installed the pads backwards, causing the metal to grind over the last four days on the wheels of his Camaro. Yep. That would cause some grinding, all right. We're still scratching our heads trying to figure out why this guy decided to do this, and then upload it to the internet. This is a handy guide on how not to fix your car.Bottom line; just go to a professional if you're about to do something like this if you're not entirely sure what you are doing. And, seriously, DON'T resurface your rotors by hand.
