If either or both sides drag, you will the need to have the calipers rebuilt or replaced. This happens because of corrosion in the caliper piston chamber/bore which causes then to retract slowly or to stay out which keep the pads engaged with the rotor, thus causing the drag.
It could also be caused by a damaged caliper piston seal (which still requires the caliper to be rebuilt or replaced). The seal inside of the caliper and prevents brake fl
fuid from leaking and it also retracts the piston once the brake pedal is released.
If you happen to be driving near home or a place where you can raise up the truck and it starts to drag, simply raise the front tires ant spin them by hand. If one is noticably harder to spin the other, that's your dragging wheel (keep in mind that it should be very hard for you to turn by hand-since you can feel it as you drive and the engine produces much more power than you can when turning the wheel by hand).
