Start by turning the truck off! Oh, and I'm not a brake guy, but I have done the brakes on many-a-car.
Your caliper pinches together which results in the brake pads clamping down on the rotor. When you change the pads, the caliper has pinched down quite a bit. The new pads are thicker than the old ones, that's why the caliper won't go back on.
First and very important step... take the lid off the brake fluid resevoir. Put the old pad back on the caliper on the side with the piston. Use a "C" clamp as a press and slowly turn and press the piston back into caliper. Make sure you are centered as well as you can. Push the piston all the way back in. Be sure not to damage the rubber seal. Be advised, some fluid may push out the top of the resevoir when you do this.
When you have finished pushing the piston back, you should be able to put the new pads on. Be sure to carefully clean any corrosion off the guide pins. Lightly lube them with a quality high temp grease so that the caliper slides and returns properly.
