I am going to do a front brake job on my 1997 Elantra, I am replacin the pads, rotors, and calipers. I need any info to help me do this job I have a couple of buddies helping me but I would like to know an important info such as how to remove the rotors, is it hard? Any specia tools? Do I need any more parts? Any one with info from start to finis of this process would be wonderful, thank you very much
