Gday Shane,

A couple of things I can think of at the moment in regards to correctly setting up a completely refurbished brake system.

Brake shoes - completely wind off the minor cam adjustments (this is only temporary) so they are "out of the way".

Ones at the bottom are called the anchor pins they have a small drilling (hole) in the end of them. These are set up so the holes are opposite each other.
I know a picture would help at this point but I can't seem to bloody well find any.

Doing this will get your shoes in the correct position to do the minor adjustment (with the Cam's)

You will need to be able to rotate the drum for the minor adjustment..

Adjust the cams to make the shoe come into contact with the drum
There should be just enough drag for the drum to be turned by hand.

That's your shoe set up done.

For the booster, I recommend you look at the Instructions on driving, maintenance, repair book. (The little book with Special pattern vehicles on the cover)

Basically (very basically) there is a small rod inside the piston rod (the outside rod). When you press the brake pedal the small rod has to move first to seal the air chamber. It is only small movement but this is the critical part of the set up.

It will provide a vacuum one side and atmospheric pressure on the other and gives you the power assist. You'll feel it when pressing the brake pedal.

Any hoo - hope this hasnt been too confusing - I often work out how things work by reading the manual under the truck, looking at the bits they are talking about, then reading again (repeating these steps 20 times if necessary).
