Should all of your brake lines be converted to be the same size or does it not matter if you run w/ a prop valve?

I have such a frankenstein of Jeep parts on my YJ. I have a rear disc brake set-up from a Ford Exporer, the front is Ford outers with a Chevy knuckle with the Chevy 1/2 ton caliper/rotor set-up. To top that off, I have a Ford E-350 M/C and a YJ booster and no proportioning valve. I know the Chevy caliper is 7/16", haven't found out what size the explorer is yet, only found a part #, and the M/C requires brake lines that are 3/16" front and 1/4" rear.

So, should I buy one bulk size brake line and run it all the same or do I have to make the lines all specific? Where can you get a coupler that converts brake line sizes? My local parts place isn't that well supplied.

:eek:

The only place we could find anything worthwhile when doing something very similar to your build was a small hole in the wall parts place with old guys, NAPA, and (custom soft) brake line/plumbing shop. Between the three of those places we pieced it together well enough. Just ran whatever fit with adapters where needed from NAPA. The soft lines off the explorer calipers takes 3/16" lines, same as factory yj. Just make sure you don't get the nuts with the flat leading edge. make sure as soon as you start to thread it in there's threads there, not a small flat surface. They don't seal all that well, or in my case, didn't really go in at all.

Thanks alot for the replies. I'll check out speedway. I hope they have some JIC fittings too...gotta plumb up a fuel cell while I'm at it.
