The hydroboost is on the back burner at this time due to some other issues with the truck,m had to spend some & on the ignition, tires, and other stuff just to keep it on the road. Also have to get the ABS figured out first too. The light is on and the brakes as they are are negligibile. There's alot of info on the swap on other websites, and I think I'm gonna go with new or rebuilt parts from the get-go instead of doing the junkyard thing. Seems like the way to go for the money and work. Planning to go with the hydroboost and upgrade to the better calipers also, yes they were stock on the 1 tons and some HD 3/4 tons also IIRC, but I think it will be much simpler to just order the correct stuff foom O'reillys or somewhere and be done with it. There's plenty of info telling exactly what to order on the other message boards, even the part numbers and everything. Try fullsizechevy.com, and follow the links.

Yeah the brake fade is really something I should have addressed well before now. I personally don't plan to do the rear discs, seems like too much $ at this time. Some are working on adapting available parts (mounts) instead of custom fabbing them, which, if accomplished, will get the cost down and I might do it then if the cost/work/benefit factors are favorable. The front brakes do like 80-85% of the braking anyhow, so that's the place to concentrate first, to me.

Have you considered the Hi-4 headlites yet? A cheap and simple upgrade that should be right up your alley considering your electrical skills, and yeilds outstanding benefits for the work. I personally took it to another level by wiring in a toggle switch (mounted at the bottom of the dash near the parking brake release), so I can have either just the low beams, just the hi beams, or both. Has worked out well so far and is one of my favorite mods. Now maybe some auto-dimming headlights adapted from a Caddy or something?

Both are on the to-do list.
