Well I went ahead and did some bleeding on the stock system with the assistance of my father in law. I can actually get a firm pedal after 3-4 pumps. It stays firm and doesn't bleed off, so my wheel cylinders might still be good. It looks like someone replaced all the rubber lines, they look practically new.
Next week I'll be taking down three large Doug firs on our property. That's going to produce a LOT of limbs, and there's a place that will take them about 1/4 mile down the road. I don't want to know how many trips with the Silverado this would take, plus dumping them would be a lot nicer than unloading by hand.
In preparation, I finally got the old gas pumped out, replaced the fuel lines, and fired her up. She seemed to run pretty decent today. I'll try adjusting the brake shoes and see if that helps. I might have to bleed the hydrovac too. After that, some fresh stake sides would make this thing basically usable. Hopefully she'll be ready in time for her first big job!
