I just replaced the long line from the pressure regulator to the rear
junction and the lines from there to the flex lines. Can't you just replace
the short line from the rear wheel cylinder to the flex line? I paid $5 just
for a joiner. A new piece of line is less than that or about the same. Plus
you don't have to flare the existing line.
