One tip I would add is that when you are finishing up the rear brake job
and bleeding the brake system to get rid of air
don't press the brake pedal down all the way....
just do multiple 2-3 inch presses of the pedal.
This keeps the master cylinder piston from going too far forward
and out of the range of "normal" braking travel and
keeps the old piston seals from getting damaged by the rough lip that is usually
worn onto the bore walls where 'normal' piston movement stops.

Ok ... it's done. The only issue I had was backing the star adjusters off to get the drums back on. Even though the shoes had about 1/2 the material left on them, the right drum wouldn't go on until the adjuster was backed off ALL the way. Even then, it was a TIGHT fit! I wonder what I'm going to do when I need new shoes now. [>:]
I used a vacuum pump to bleed each cylinder so there was no issue with only going part way on the pedal.
Parking brake used to go almost to the floor and not really hold the truck. Now it goes about half way and holds firm.
Ran it around the neighborhood. Didn't notice anything startling. Did notice better braking FEEL ... less nose dive on a harder stop. Didn't try to lock them yet. That comes after final adjustment. Pedal's a LITTLE soft still. Probably need to bleed the entire system the old way.
Whole thing took about 2 hours (including cussing at the right drum ... hey ... it's HOT down here).
Oh ... and don't sit in brake cleaner ... [:@]

im confused i thought the original instructions (from Rom) said you didnt have to take the shoe off at all? did i misread it? or did you take it off for another reason?

I didn't take the shoe off ... I just disconnected the return spring that holds the front shoe in place. He claims (later in the instructions) that this MAY be optional ... but these wheel cylinders are pretty big and space is pretty tight. It took some twisting and turning to get them in even WITH the spring off.

Oh ... another thing. I noticed this driving to work. The brake pedal seems to travel about 1/2 to 3/4 inch farther before I notice any real braking action. Not far enough to raise the hair on the back of your neck but enough to get your attention. A quick pump on the pedal fixes it but I don't really like driving that way.
I don't know if it's because the rears aren't fully adjusted (can't see how the right needs ANY at all) or if it's due to the increased capacity of the cylinders. I'm leaning towards the latter. I guess everythiing had to settle in and line-up right before I felt it.
Anybody know if a 1-ton master cylinder will fit on a 1/2-ton? I want to shove a LOT of fluid through the lines when I stab the pedal. [8D]
I wonder how well the self-adjusters will work now ...

It's best to adjust them they way I outlined in my write-up.
