Some backstory: the Dakota had been sitting for a year or so before yesterday's 13 hour excursion back to Michigan. Worked up to it though, short runs around the neighborhood, then longer runs out to stores or the gas station. had no issues through most of the day until I hit traffic around Cincinnati. Once I was clear of that I noticed that the truck was draggin' a bit. My first thought was a flat tire, but as soon as I touched the brake pedal I eliminated that. The pedal was instantly firm. No play at all. and that meant one thing to me so I pulled off at the next stop. sure enough, the front brakes were wicked hot. Not glowing, but still very very warm. Water was instantly boiling off the calipers. So, not having the tools to easily deal with this in the middle of nowhere (I know, shocking right? except that I left the hydraulic jack and wrench with my dad in case he had need of them in GA or with the trailer). I went with plan B. a bottle of water, some WD-40 and crossing my fingers. I cooled the calipers down as best I could, then soaked all moving parts with WD-40 and took the opportunity to stop for dinner. seemed to do the trick and, while I was easy on the brakes after that, I didn't have any more issues.
So my question is, what do you think the original problem was? The brakes were sticking evenly on the fronts. I would think that if one caliper was sticking, only that wide would be affected and the truck would want to wander in that direction on the road. it ran straight the entire time. Later today I intend to pull off the brakes and lube everything up properly, but if this was a master cylinder issue it may be for nothing (although I guess it's still a good maintenance thing regardless).
