Troopy Travellers (NSW)
I decided to remove the rear brake drums on my FJ75 troopy,to blow out the dust &
check the linings. Thinking this would be easy like for my old Holden."wrong again" Can't get the buggers off. The cheapo manual says undo 2 screws on the drum face, but I can only find one screw?? I noticed that there are a few tapped holes in the drum, is this to attach a wheel puller. Anyone know how to get them off?

Sparky,
Two things, my old HJ75 had one countersunk screw in the rear drum. Remove that and your part way there.
The tapped holes are as you say, for removing the brake drum. I bought a couple of Hi-Tensile bolts with the right thread and used those to pull the drums.
Tension them up and then tap around the drum with a hammer, when it moves tighten the bolts some more and repeat until drum is off.
Other thing, if the drums have a bit of age on them they'll have a lip on the inside edge. This will make them impossible to remove if you don't back off the brake adjustment a bit. Basically the shoes wear into the centre of the drum causing its inside diameter to increase, the shoes adjust out to compensate.
The inside edge of the drums doesn't wear, no shoe contact. This means you are trying to drag a drum over shoes that are bigger in diameter than the whole you are trying to pull them through.
Hope this helps,
Geoff.

When trying to back the knurled adjusting wheel in the slot (remove rubber bung) have a look in with a torch and you will see there are saw like teeth on it.
You need to turn it backwards so that the high points of the teeth are going first .
There is a flat piece of spring steel that catch the teeth to stop them turning backwards and releasing the brake shoes.
I have a piece of no 8 wire bent in a slight arc, put it in the slot in the backing plate and over the wheel cylinder next to the teeth on the adjuster, if you push on it you will feel the resistance from the spring steel, you only have to push it about 1/8 " to allow the toothed wheel to be turned with a flat blade screwdriver.
