an emergency!? Currently in school and working, this is my only car and I can not afford for it to be towed and worked on. I've replaced the disc brakes of one other car. I can't find the directions.I need to do this by tonight, because I work tomorrow evening. Please give me a website if possible. I would like a step by step with pictures.The brake pad is down to the metal and is grinding the rotor. Thanks ahead of time.
