My advise is to take your time and study your truck as you go. Jack up the front end and remove the wheels and brake drums. Only rework one side at a time. Do one side from start to finish and use the other side as a reference. If you forget how a spring goes on or an adjuster or whatever, you will have the other side to look at. Left and right side brakes aren't identical, so don't strip one side down then rely on the other side for reassembly. Take notes or even pictures if you are unsure of anything. Brakes are the most important system on a vehicle.
Good luck,
Scott
