Are you planning on ever taking it on the road? The wheel cylinders will be completely full of gunk and rust. I've had a few of those really stuck brake lines when I did my A2. On the 109 I just put a good amount of PB Blaster on every fitting that needed to come off and it's lived up to the hype so far.
On the road? Hope so. If all goes well it will be hauling grain and potatoes this harvest season.
But I am definitely a "safety" guy. Especially where brakes and steering are concerned. It won't be used unless it's right. I'm quickly running out of time to work on it, so if it's not ready for this year, then it'll wait until next year.
But, I've been amazed at how many of the systems on the truck work so well with so little effort after sitting for so long.
So, I can't help being a little curious to see how far I have to go to get the brakes working.
PB Blaster? I should own stock in that company, use a lot of it. But for really stubborn stuff, nothing works better than "heat + hose + vice grips". The hose is there for two reasons. First, it's there to put out the fire so you don't burn down your truck/shop/house when you set something ablaze you didn't intend to. ("What's that you say honey, you smell smoke? Don't worry, it's just a small fire. I've got it under control"
) Second, "heat + quench" is a great way to break that rust free.
Local parts house was out of brake line. Ordered some, it'll be in tomorrow.
