I've looked all over for the answer to this question but just can't seem to find it. I have a 1999 sportage 4x4 and need know what positions the caliper bolts go. 2 kia mach. told me that the ones with the rubber boot goes on top on both sides of the car however one post here said bolt w/rubber boot on top on driver side and bottom on passenger side. don't know which one is correct. By the way, this is a great site with lots of good info. thanks.
