I've found that my rear brakes are dragging, and now it seems worse than ever, if i drive past a barrier or a car i can hear the sound of the rear brakes lightly on. And i think it might be the cause of my poor mileage.

How do I adjust the rear drums for they dont drag, or as much. It may be the parking brake to... when i got the truck the brakes were just done. so maybe they wern't adjusted. and i had alot of slack in my emergency brake, but i didnt mod anything when i did my 3"body lift, its not tight now, it still has a little slack when its not activated.

I've always heard the rear brakes adjust as you are reversing. Don't know how true that is. You might check for a swelled brake line or check and see if that parking brake is not staying engaged.
