Brakes Making Clunking Noise

Brakes Making Clunking Noise
Hi all! I'm new here and so grateful for any help.
I've got two things happening with my 2001 GC Ltd, but here's the one I'm most concerned about: the brakes have started making a clunking noise. It happens pretty regularly - probably every tenth brake or so, but not every single time I brake. I've tried pumping the brakes to see if I could reproduce it, sometimes it makes the sound, sometimes not. No clunks at all when I go over speed bumps or hit pot holes.
I recorded it - you can hear the sound quite clearly here (literally in the first second or two - had to upload a bunch of black so file was big enough):

Thoughts?
Thanks in advance!

The caliper mounts on a bracket with 2 slider pins. They are 7mm allen. The bracket mounts to the spindle carrier with 2 bolts. I don't remember what size they are, but these are the 2 they're talking about. Most of the time they require a long breaker arm to loosen, but if they weren't tightened properly on the last brake job, they could be loose. This bracket must be removed to pull the rotor.

Yeah, the WJ has dual piston front calipers. IDK what your XJ has. They are huge compared to the older ones. That's why they had to change the bolt pattern and go to 16" wheels.
