89 911 - Dragging Calipers

I am 99% sure my front calipers are 'sticking' on my 89 911 cab. I still need to jack the car up and do a manual rotation test, but I can feel it dragging, and the car is very difficult to roll by hand on a flat surface.

I had this issue years ago, to the point where the brakes got very hot on a long-ish drive and I lost brake pressure briefly. I thought I had solved it by replacing my flex lines, but the problem appears to be back.

The car sits a lot, and only gets driven about a dozen times every summer.

Should I do a caliper rebuild now? I'm not sure hat causes the problem, and the internet searches haven't lead me anywhere useful.
