Thank you for that Mike perhaps Chris can put on the website for easy future reference.
A lot of people faced with changing shoes or the slack adjuster for the first time, end up trying to wind the shoes off in the wrong direction using more and more force causing untold damage to the slack adjusters, it's therefore important to read the Manual or RSE Instruction about the direction to wind off as it's different on front and rear wheels.

That makes it sound so easy! Dealing with recalcitrant split pins, a fiendishly powerful C spring and a really quite awkward linkage return spring just adds to the joy. The brake drum does tend to come off a lot easier if the hub seal has soaked everything in oil. Wear goggles.

Then you have the fun of replacing the oil seals and relining the brakes too! Don't forget to fit the right ize rolles on the shoes.
