So my '96 busted a main brake line on a trip up north where its still sitting. The line runs from the rear connector on the master cylinder to the square shaped fitting behind the front drivers wheel. New line seems to fit sungly into the master cylinder, but for the life of my I cant get it to thread into the lower fitting. I bought a 3/16 brake line from autozone, which has the same screw sizes on each end. I'm reading that the screws on each end of the line may be different sizes? The question is, does anyone know what size I need and where I can get it? Nearest auto parts store is 30 miles away from the truck so i'm hoping to go prepared next time. Any advice is appreciated!
