Hi Jay,
Its not too difficult.
1) You first need to get both wheels are off the ground. You actually don't need a jack for this. Simply tilt the forks as far forward as you can and place a block of wood under each upright. The blocks should fit snugly. I used a piece of 4x4 cut the correc length for this. Then tilt the forks back all the way and the uprights will fulcrum off the blocks and raise the wheels off the ground.
2) Remove the wheels from the hub/drum. I was unable to remove my wheels as they were frozen on. This made the rest of the steps very, literally, heavy.
3) Drain the transmission. The tranny and differential use the same oil, 80/90w gear lube, so you need to drain the tranny to drain the differential.
4) Remove the nuts holding the axle shafts in place and remove the axles.
5) Remove the hub locknut, lockwasher, etc
6) remove brake drum/hub
Now you can disassemble the brake shoe assembly. In my S30 I had two bad/frozen brake cylinders which I had to replace. The shoes were greasy and required some brakleen and sanding to correct. I could of got them relined but decided not to.
7) reassemble is the reverse. Cleans and repack the wheel bearings while you are there and also install a new grease seal.


In step 2 if you couldn't get the wheel off the drum/hub I suggest you do it now as its a **** to finish the job. Its much easier to bleed the brakes with the wheel off the brake drum. I had to use an acetylene torch to heat the studs red hot and then a sledge hammer and block of wood to hit the center of the hub to knock it off the wheel.

I've also repacked the seals on the tilt cylinders and lift cylinder. Not too bad to do.

Here are some common part numbers cross referenced for easy ordering. I got them all on Amazon.
