I have a 63 beetle, and did a brake repair like you did last winter (2018). First time ever doing it and I ran into some of the same issues you did. Definitely a good learning experience. It isn't my daily driver so I was able to take my time (non emergency mode). Thanks for the video! Good work!
A product that I'm very addicted to (but get no financial compensation from mentioning!) while working on rusty cars (I've owned Mavericks and Novas) is PB B'laster. Soak the stubborn nut with it, let it do its thing for a little while, and it will save you many expended profanities and busted knuckles. I'm pretty sure it could have prevented twisting off that break line at the wheel cylinder, it penetrates really well and would more than likely freed that up. And, if you ever want someone to think you've been working on cars all day, a couple of drops of Blaster on your hands, and you'll smell like a professional :) And definitely get some brake line wrenches, like Michael D. said. You probably won't use them too often, but man, they are cheap insurance, and if you ever have to take transmission cooler or other brake lines off, they are irreplaceable. Great video, though, nice clear shots of the stuff you were talking about.
First, get an Orange Bentley Manual. There were a number of mistakes you made, which could have been avoided if you’d had a heads up from the manual. Second, use a spray brake cleaner. It makes the job much easier. Third, use six-point brake-line wrenches. Harbor freight has them for cheap. Third, completely remove the adjusters, clean them, and lube them with never seize. That way, they turn easily when adjusting. Reinstall them so the angled slot matches the angle on the ends of the bottom of the new shoes. Don’t install them upside down. Match the angle. Also, be sure to adjust the adjusters all the way in at first, so the drum will slide on easily. Fourth, replace that seal on the inner side of the drum. You didn’t mention this. They’re cheap. Also, well, I won’t write a novel. Get a Bentley or Haynes Manual.
Every time you remove a wheel cylinder, you definitely must bleed the system. The reason being the new cylinder isn't supplied with fluid inside them. So that's where the air will be.
Half the action! It’s because the drum is off. If put together, the right shoe would contact the drum, forcing the left shoe out more. Perfectly normal.
You have no real idea what you are doing ; for all those seized nuts on brake lines get a butane torch and heat up corroded parts ! So many mistakes I couldn’t believe what I was watching
