I put my parking brake on and I guess it didn't come off. On the way home I smelled something, which was one of the rear drums smoking. Rather than strand myself, I tried to go the rest of the way slowly, making stops along the way to let the brake cool off (I had no lube or anything with me to break stuff loose). I could tell at the end that I made a mistake since it takes way more pedal travel to stop now. I must've really worn down that one brake. So... how tough of a job is replacing the shoes on 1-ton M1008 drum brakes? Which vehicle should I tell them at the parts place to get the right parts, since the drums look huge, probably bigger than a standard K30? If this is a frustrating job, I might cave and have a shop do it the first time, since everything on this truck is so rusted. What do you guys think?
