Stop in for a cup of coffee

So, my 92 D250 truck sits here when I'm gone. Usually for 6 months at a time. Spent a lot of time cleaning it up a couple of weeks ago and used it to move some things for somebody. I noticed on the way home it was starting to pull a little bit to the right. So when I got home and parked it, there was smoke coming out of the left front wheel by the brakes. So I'm assuming the Piston and the caliper was hung up or some such thing. I drove it again the other day and seemed okay. I just took it on about a 12 mile drive to fill my garage gas cans, I took my temperature gun with me to check the calipers and rotors when I got there. Both sides were the same, calipers and rotors. Same thing when I got home. I've been jamming the crap out of the brake pedal so maybe whatever was hung up is now loose. Calipers are only a couple of years old anyhow.
