Why use DOT4 for flush when good ol' denatured alcohol is the recommended flush by brake component companies, a lot cheaper, a lot less messy, will dissolve sludge and carry out any water. Then fill with DOT3 or 4.

I appreciate all the advice. I really haven't been in the mainstream repair business for a few years now.
I've have noticed sometimes people really want to be helpful and sometimes they just want to prove how much they know.
When I have a fresh quart of brake fluid it is cheaper than the $5 worth of gas to drive uptown to buy alcohol (which I have never used, thanks for that tip).

I removed the calipers today and they moved freely on the pins. I emptied them out and bleed the system I haven't driven it since. It really needs a complete brake job, including hoses and at least one rotor. I will have to evaluate if it's worth the investment. I may just pull the propane system, ZF 5 speed and the tires/wheels and take the rest across the scale. It is a decent looking/running truck but has bondo and the odometer shows 200,000
