    i had ordered my flex lines from Xtreme Crawlers back in July and just finally getting to installing them on my project K5 (im a procrastinator).

    well the rear dropdown line was made with a fitting for 3/16"s fittings (even though i specified 1/4"), does anyone see a problem running a 3/16 line instead of a 1/4" line to the rear discs?

    or should i see if he will swap the end out for me?

    I'd run 1/4, if thats what you asked for. 3/16 is 25% smaller line, I think that would make a difference. :o

    I think you'll find that most cars with 4whl disc are using 3/16" front and rear. I just replumbed mine with 3/16 all around. 'Haven't driven it much (just a test drive before I tore the engine down) but it felt and stopped great! :waytogo:

    and i specified that the line all the way back would be 1/4", but i also told him that i have rear discs. so i dont know if he figured i wouldnt need a 1/4" capacity.

    doesnt one of them (disc or drum) require less volume or something like that?

    I would rather have a 3/16" line than a 1/4" line. You don't need a lot of volume for disc brakes.

    My local Napa has several size adapters to this. They even had one to go from a 9/16" thread to a 3/16" line for my old Ford. Good luck with it :thumb:
