The weather finally broke and I have had a little time to work on it. The hubs and final drives come out very easily and required very little persuasion. The shoes looked fine and the wheel cylinders were leaking. I was able to source the wheel cylinders quite easily via a forklift outfit. I bought both master cylinders and both wheel cylinders just to finish the job and make sure no further issues. It took more time to degrease and wash the hubs than to do anything else. I am having an issue with the 1/8" tubing that extends the bleeders to the wheel cylinders inside of the final drive housing. It leaks and needs to be replaced. 1/8" tubing is hard to flare and find.
