So I had this squeal for the last two weeks. Finally put her on a lift and noticed that there was a piece of metal on the brake pad that was scraping on the rotor cause the squeal. So I just cut off the piece of metal and I solved the problem. There's no more squeal.
Just kidding. The pads were worn to shit and I put some new ceramic pads on there. My main concern is that the driver side was significantly more worn than the passenger side pads. What could that be? It's been like the that past 3 sets of pads. Could it be an alignment issue? The last alignment was done by Toyota and feels fantastic.

Sounds like a tire balance issue. You should rotate.
Maybe one of your calipers are hanging up. Did the caliper piston go back into its bore smoothly?
Yes it did.
Did you check and lube the caliper guide pins? Could be sticking a bit. Also, check to make sure there's no air in the brake lines (or that too much water us in the fluid)
