Just got done with a brake job on my Trooper - I had one set of pads worn this way. It was VERY obvious.

There's a post that runs through the top of the caliper assy. The post is mounted on the removable bracket that holds the caliper. The entire caliper rotates on this post once you've removed the restraining bolt at the bottom. This post also more or less aligns the entire caliper assembly.

Mine was bent up a few degrees. It was noticable - so much so that when I went to rotate the assy down on the new pads, it was visibly out of alignment with the disk & pads.

So I gave it a couple of strategically placed whacks with a hammer (after removing the caliper assy) to get it back in line. Once I'd bent it down a couple of degrees, it fit perfectly.

You do want to be careful not to bend it too much or snap it off - that could get expensive. But I managed to fix this in about 30 seconds.
