i would check the rubber lines on all wheels since you said front wheel was smoking sounds like a line may have delamed and won't release caliper...
replacing the rubber hoses would be cheap insurance as the older dodge trucks have weird brakes to begin with
..i drive a 93 d-250..
also the snythytic fluid is silicone and it doesn't take heat well so use regular fluid.. dot3 i believe yours takes...and bleed till comes out clear 2 quarts of fluid should do it
unfortunately you may need to replace the pads and have rotors turned or replaced as well if was hung up
