I live in the Salt Belt. I've seen the slides on one caliper bracket go bad from salt intrusion, and the other side is fine. Clean the pins, change the boots, or get a new caliper bracket with new pins and boots. Example: driver side pads are done, passenger side pads had plenty of meat. So yes, the Salt Belt is a different animal to contend with. It sux, and will finally be moving out of this belt in 7 yrs. Every spring, I have to take everything apart, clean, re-lube, or replace. I have many stocked parts when needed. Calipers / brackets / boots / pins/....it's sheer insanity in the Salt Belt. Constant maintenance . I even scheduled my back surgery for June of 25', knowing that by April of 26' , I'll be well enough to tackle the jobs .....
