Front brake pad slop/stick - how to fix it?

[Orange]

My left front brake pad has some slop in it apparently. It doesn't ride in tight enough tolerance to the rotor to stay in it's fixed position when the rotor hits this one spot every time around. This is most likely due to a slightly warped rotor. I say slightly because it isn't enough to feel.

My question is this...how do I keep my pad from clicking every time it hits that one spot in the rotor? It's driving me nuts!

Here's a short vid of it. Watch it a few times, and you will see the pad jump at the end. You can hear it click - but you can actually see it if you watch for it a few times.

BTW - Further proof in that vid that my truck IS a daily driver. HAH! Look at those dirty wheels! (Dirtiest they have been in at least 5 years).
