I was about to post the same suggestion as @Tester on your other thread.
I think I’ve seen more hoses fail than calipers - recently fixed a Camry behaving just like Tester suggested. The brakes seemed to work fine during normal use, functioning without pull. However, if I slammed on them hard enough to engage the ABS, it pulled to one side pretty hard - the hose was constricted enough that the fluid didn’t pull back with the ABS, so on one side the brake was pulsing properly, but the other side it was pretty much on full-bore.
If I checked the brakes after the vehicle had been sitting for a few minutes, the wheel turned freely, as the fluid slowly drew back and the piston retracted. However, after a run around town, if I stopped, I could not only feel a bit more heat on that side, but I could tell quickly by touching the lugnuts on each wheel. The wheels where the brakes worked fine were hot - but I could hold my finger to the lugnut for 10 seconds or so before it got uncomfortable. On the dragging side, I couldn’t touch the thing for more than 2 seconds, the lugnut was so hot.
The caliper moved fine, but the hose was slightly constricted. Replacing the hose fixed everything just fine.
Because of stuff like this, if I ever have a brake hanging up, I tend to replace the caliper and the hose at the same time, without even bothering to diagnose the exact source. The parts really aren’t that expensive, so spending $70 to do both and guarantee its fixed is easier than spending $40 to find out you have to do the job again - particularly since you’ll end up bleeding brakes all over again, and that’s just a serious waste of time to do it over and over…
