We've set up this line kit to help install that new drift brake you've got. The flex line is specifically designed to connect domestic type reservoir master cylinders (like Wilwood) to Japanese import style hard brake lines that use the 10mm x 1.0 thread.
The line is 18" long so there's plenty of length to route it without having to fight bending those hard lines up to the master. The banjo style fitting keeps it low profile while allowing you to index it in any direction for cleanliness and simplicity.
The reservoir style master cylinders are commonly used for stand alone drift brake systems and thusly only have one output line that runs to dedicated calipers in the rear.
