Sorry, Nonstop, after re-reading my first post, it looks like I didn't make that very clear. My bad!
But yes, Im looking for where the four black shims go. I just made a 3,000 mile trip from GA to Seattle withOUT them installed and had zero issues other than some new noise. I noticed when it's cold the brakes sound like they squeal a bit more than they did the first few weeks they were on (fronts). And another thing is that it sounds like the new brake lines are a little groany. What I mean is that from a cold start, I can put it in reverse and back out somewhere and I hear "rrrrraaaaaa, uuuuuuuungh" kind of sounds like it's been sitting for years.
Has anyone else had these kinds of noises after installing brake lines? Ill get pics of the shims when I bring them in and maybe if I can think to do it, Ill get a video with audio of the noise it's making now.
Edit: I was just watching some videos on diagnosing new brake jobs causing squealing and the guy in the video lubed up more spots on the caliper than I did. I just hit the metal to metal surfaces on the brake pad itself (not the friction surface that contacts the rotor), so this could be part of my issue. It's time for my 50,000 mile check with Jeep now anyways and it's also time for an oil change so I may just have that and brake inspection all done at once in the next few days.
