Do I need a new caliper?

For funsies... now that it's back together... the noise is a bit different, but I have only driven a few miles and there's a new popping noise, so that whole big diversion may have changed a little because the sounds are different, but not a lot.

My plan is to search this forum and the larger web again. I also think maybe I should make a recording, but I'm not really sure how well my phone will pick it up after this. My kids have better audio equipment, but that would turn it into more of a production.

If I do get a sound or find a better way to phrase my question, I guess I'll make a new post.

I'm also planning take the tire off again to inspect the piston and boot. If that ends up being an issue, I'll reply to this thread.

Again, thanks to everyone for the help.
