alright, I got everything put back together finally. The pads with the squealer had to be put on the inside of the rotor (the side closest to the strut) or else the Caliper wouldn't go on correctly. I also learned that you're not supposed to take both bolts off of the caliper to remove it.. You're supposed to only remove the bottom one then rotate the caliper upward out of the way then remove the pads. after doing this, re-installing the caliper was much easier. After a test drive and a few harder stops I noticed that the brakes feel much better than they had before. Initial braking is a lot better. I think this might have been the problem all along.. Now I just need to get the brakes bled after I get my rear brake pads/rotors replaced.. no sense doing it now since I'll just need to do it again later on. I think I'll have a shop bleed the brakes for me. The wear on the rotor is now even too. Both sides are equal. It'* a great feeling to FINALLY get it working right.
Thank you everyone for all of your help! Especially Willwren, I really appreciate all your help and for putting up with my nieve questions.
Just look at how badly this brake pad was worn down on one side. (this is the pad that was on the passenger side, outside of the rotor..)
