So, for two weeks I've been riding on pads that are gone, I was just scraping that little metal hook.. Went and changed the rear ones first last friday.. rode good and the squeeking was gone.. Saturday I changed the front ones, they still had some decent life left.. After I did a complete brake pad change, the trucks been riding like.Going around 45-55 the truck rattles like I'm on a dirt track.. took the front ones off to see, and they disc was loose, so we tightened those little spacers down (I didn't know the use of them until now, so they were never tightened).. went and ride and its still doing the same thing...Took the back ones off and noticed the passenger side was stuck, so at first I thought my diff went out, but upon further investigation I noticed that the passenger side was scorching hot, and that the caliper froze up.. I don't know if its just that one, but since I changed them the trucks been riding like. Hopefully somebody can help me out a little.. Pics followed..
