Be mindful that if the AC was on, and you stall the car or stop for fuel you should turn it off and leave off for some minutes, to prevent overpressuring the compressor, since you're not considering the pressure before starting the compressor.
In my mind, where pads bind is where they slide, not where they're clamped against the disk.
Pulling them out and making sure that where they meet the spring, the spring itself and below the spring is clean and smooth would be my bet if they're sticking and/or squealing.
Have you checked the steering column bushing on the passenger side for play?
It's a common wear item on our cars

More toe out loads the tire the "other" way than the corner. It's scrubbing the inner shoulder, and the cornering makes use of the outer shoulder or the outer wheel for most of the support.
It just feels more nervous as the inner wheel is pulling extra to whatever side you turn. But that's...
I don't know if tire patching plugs are "fuel safe" but that would be something that would not come off easily by being a press fit into the hole

I feel that it should be to allow longer springs and extra lift (with adequate pistons) without spring bind?
(or did I interpret your words the wrong way?)
