I see I have the inboard mount drums (darn!). No slotted screws between the lug bolts and the hub sticks out 4 to 5 inches from the drum.
Well, the adjusting screws are backed all the way off, the emergency brake rod / cables are loose and the other wheel turns....So I think the next step is to put a single wheel back on each side in the back. Put a bunch of weight above the rear axle and pull the truck to try and break the brakes loose on that side. We have a block of cement that weighs about 1,000 lbs. If for some reason that doesn't work then I guess I'll have to break down and take the hub apart and try to pull it that way. I'm not sure when that is all going to happen, maybe next weekend. I'll let you guys know how I come out.
