I'm using a nylon kit on a tube buggy; need to get from the supplied 1/8npt to 10mm on toy calipers/mc (6 pcs.)

i have found these @ $7 bucks ea. + shipping; but alas, I'm a cheap zukker!

Any other ideas??



  • 10mm - 1/8" Female

  • Used to Connect Plastic Line to Metric Calipers

Nylon brake lines scare me. Are you doing this to try and avoid using flex lines at the axles? If so, I'd advise you to rethink your plan. These are your brakes. Don't mess around. If you insist on using nylon vs. metal, at least terminate them at a fixed point on the axle or frame and use a custom flex line after that. Any reputable hydraulic shop should be able to make them for $15-20 a piece, a few bucks more if you want braided stainless. I just can't imagine that the nylon would hold up well with the repeated flexing of being at a corner. I wouldn't even trust it on a frame run!
 
Throw that nylon in the trash now. I have watched two buggys in past year blow lines due to heat from the nylon line. One about ran my ass over. Get some aluminum and a nice flare tool.
 
Nylon will also make your brakes way spongey. Contact billy at alliance hose and tube in greensboro and he will fix you up.
 
I ran nylon lines on my last buggy for about 4 years. worked great for what they are, easy to work with. Only trouble I had out of them was a tree branch that ripped a line off, but they are easy to fix on the trail. That fitting you found is probably the best way to go. I had more money in fittings than the line kit itself. Just keep them away from heat and sharp edges and you will be good.
 
Billy is good. Made all the brake lines on my jeep. But a few weeks ago I was in alliance and he said he was leaving and taking another job but didn't mention where.
 
What the heck kind of Nylon tubing is good for thousands of PSI? This is a really stupid idea. Brakes are your last life line, don't cheap out. Seriously. Braided stainless lines are cheap. If you cannot afford the hobby don't play in it. At the very least use all metal lines on the frame and axles and quality reinforced rubber hoses for the flex lines.

I do not usually rant but this one is worth the argument.
 
For less than $150 you can buy a traditional brake line kit with whatever fittings you want. I wouldn't trust nylon. Stainless lines at $20 each is cheap insurance. A good flaring tool and a few minutes practice you can flare your own lines. If it don't leak, its good.
 
geez; it a bus load of nuns scenario!

thanks Mark; you know I respect your opion-ion- (mostly, lol)
not trying to avoid flexline drops; just trying something different.

non DOT, off road only.

nylon line is rated 1900>2500psi; this kit is 2500, more than enough

I have researched this thoroughly; this line is used flat track/dirt track racing extensively. MANY years...thousands of rigs.
check it out for yourself (or don't)


Yes; you don't want it near heat/sharps, and if it fails, it's generally at a fitting; super easy trail repair, uses standard, everyday compression fittings.
I know how to bend/flare, there will of course be a certain amount of hardline...
 
I spent 30 years in racing. Everyone preached..."you cant do that, it wont hold" Yet I have seen almost every sprint car run plastic lines, and I am seeing more and more buggys run em' including a guy I wheel with regularly!

I say Im pretty sure they're fine!

Oh..and quit being a cheap zukker!! I just paid $18 for a damn Run-Tee for a metal line setup!

my $0.02:)
 
How do plastic/nylon brake lines do against swelling and resulting spongey feel like some claim rubber hoses to have?

Depending on the braided line you get, it is just nylon tubing inside. The stainless does help with swelling though.

X2, have seen thousands of racecars running nylon lines for years. Even some cars with a ton of money in it. If you are smart when you install it will work fine. After seeing some friends run it in the woods, the ease of trail repairs make it extremely tempting. On a street vehicle I wouldn't consider it though.

Really cant answer that. That was one of the concerns back in the day when they said not to do it! But...

The best answer would be ask someone who runs em. Ask @redneckcj5guy. (Paul) He runs em

That's what kept me from running anythng but hard line throughout 95% of my system. Going careening uncontrollably across an intersection in a jeep on 42s, of course there's a bus full of Africans involved :lol:
 
ok; this wasn't a 'what do you think about nylon' thread, but where/how to easily (cheaply) go from the 1/8npt > 10mm toy caliper line.

I appreciate all the responses/concern, but guessing I will just buy the dang fittings, lol.

nylon = no DOT, off road only.
