I have a 99 s-10 Blazer 4x4. I have owned the truck for almost 5 years. I have had to change the rear disc brakes about 12 times. The last time I did it I bought new rotors. That was last summer, they are already bad again. I usually get the mid range priced ones at advance auto parts. Does anyone have any ideas what I can do to keep from having to replace them so much. Or does anyone else have the same problem? I would get better pads if I knew that they would last longer. The fronts I have only had to replace 2 or 3 times in 5 years.
