Sounds like you are in a big learning curve. The brake fluid you tasted is not a good thing, but I bet you will be careful next time. When you are under the truck just be sure nothing is in line with your face because of drips and dropped tools.There are so many AD trucks around you should be able to buy the brake line from a parts truck for a couple bucks. These old trucks are pretty simple and are a good learning tool, hope you continue to fix your own, it is really rewarding when you get it right. Both of my daughters got grease under their fingernails when growing up, and I think it was a good experience for them.
