Nick - As I was searching for a pic of the Herbrand 188 being used (I couldn't find the one I seem to recall recently seeing
but Brendan covered that), I did find this
Huck Brake Film Strip in
Brad Allen's Albums that provides some very good pictures of the disassembly, reassembly and adjustments for the Huck Brakes. When you look through them, note the non-special tools pictured for doing the various work. It also shows the use of the combination tool discussed above.
Maybe a good resource to help you not yank so many hairs out by the roots.
