Since you have the floating/sliding calipers, it is most likely the slide pins have dried out and/or the rubber boots are damaged allowing crud into the slide pin.
Easy enough to check, undo one slider bolt at the time, check the condition of it and its associated boot. clean it up and apply red rubber grease to the slide pin and into the boot.
