My biggest issue was lack of tools to do the full rebuild. Taking it apart is not the issue, but replacing bushings & getting that drum piston retainer back together was a real challenge. Back when I did it there was no internet so I had no idea what to look for when inspecting the hard parts. If I had to do it today and had all the proper tools it would be a different story entirely. Lots of great parts now to beef up the weak areas.
