My bike took a spill the other day leaning against my truck and fell non-derailer side down. The impact locked the handlebars to the right by the front brake caliper getting stuck behind the boss for the rear derailer cable (underneath the down tube). To get the bike 'unstuck' I pulled the front brake cable and lightly tried to pry the caliper from the boss. I wasn't going to force anything. It came loose easily enough, but upon closer inspection my front wheel is now being rubbed by the brake pads. One side of the caliper was clamping more than the other when the brake lever is pulled. It isn't resting too hard against the rim, the wheel will spin 8-10 times before being stopped.

Yesterday I adjusted the pads via the small Philips head screw using this video as an example of the adjustment (at 8:30 seconds):

It worked. The wheel was free from hitting the brake pads. I spun the wheel while holding the bike and hit the front brake. Wheel still free. Spun wheel again, pulled brake lever hard. The adjustment held and it looked like problem solved.

Went for a ride, only about 30 minutes and towards the end when coasting I heard the rhythmic knock knock of the rim hitting the pads. I tried to adjust it again and this time even though I can adjust it to not rub, as soon as I pull the brake lever it goes back to rubbing (like it did when the fall first happened).

I'm a novice so maybe my understanding of the calipers is not what I thought.

Any suggestions?
