Stop in for a cup of coffee

Had to drag out and clean up my 92 D250 Cummins the other day to move some things for my wife's friend. Noticed when I came home when I hit the brakes it was pulling hard to the right. Got home and parked it and there was smoke coming from the left front wheel. Heat smoke. I'm assuming the left front caliper was locked or maybe crusty from sitting for 4 months. I just drove it a couple of miles and seems okay now. Hopefully I don't have to change the caliper on the driver side.
