Brakes locking down causing extreme heat

Brakes at times would not release completely causing a noticeable drag. Tapping may release it or stopping and starting up again may help. Normally took 10 miles or more at highway speeds to trigger it. Had it shopped where they replaced rotors, pads, calipers on the front, brake hoses on the front, ABS module, ABS valve assembly and it still does it. Then had Meineke run diagnostics. They also did a brake flush. The problem happened again. Now it is less often but is more apt to happen while driving 10 to 15 miles at highway speeds. Noted though the dragging is less obvious now that they flushed the brakes but it is still happening based on the heat. Will hit 500 degrees when it does it.
