Good morning quick question for the experts. Got a 2002 International 4300 with dt466. Was used for about a year as a rolling storage for ATVS, tools and motorcycles. Started every few weeks but not moved much. We had to move storage locations, I had the driver move it about 30 miles fully laden. After that trip he reported 2 problems: right rear caliper dragging, it wasn't pulling but brakes got weak and at the end of the trip rotor was glowing. Second problem, temp peaked to about 220. Caliper and rotor are easy fix, my question is do you suspect the overheating is caused by drag on the brakes or malfunction of the cooling system? Its my understanding that the truck should stay around 190 even while working hard. Thank you
