On an F150, I can't think of anything that needs removed. Regardless, lift the rear wheels off the ground and safely support the vehicle. Then see of there is any drag on the rear wheels. If there isn't try to adjust the rear brakes through the backing plate. Adjust them up until there is a slight drag on both wheels. Next, get in and pump the brakes a couple times to center the shoes. Again, check for drag on the wheels. If you no longer have any, repeat the process until the shoes are centered and have a slight drag.
Let me know if this helps.
