What thread are toyota brake line fittings?  I am looking at converting to AN fittings.
Thanks

10mmX1, i beleive, and i think they use a odd double flare on the lines, might want to double check that

10mx1.0 is correct. There is, however, nothing odd about the flare. It is a standard inverted (double) flare.

THIS PART WILL NOT WORK!!!!!


thanks.  And no there is nothing different about their double flare.

I think this is what I am looking for

That will work in the caliper, now I need something to couple with the break line.  Mcmaster doesn't seem to have any female M10-1 fittings.

So, why are you converting over to AN fittings?   

It would make more sense to stay with factory.  That way every parts store has what you need if you need something.

Well, parts stores have stock length hoses, which may or may not work on my truck when it is at ride hight, much less flexing.  That is IF they have the hose.  There is also some Nissan hose that is much longer that works for lifted rigs, but once again, thats IF they have it.

The advantage is is any race shop carries LOTS and LOTS of AN hoses. They are the same as JIC fittings (use on industrial hydraulics).  Also, the break lines go from $85 (from marlin) to ~$30, and I can get them in ANY length, from 6 inches to 12 feet. For that price I will simply carry an extra or two.  This also makes me compatible with my friends (several of us are doing this at the same time, so that we all have the same brake hoses) so a replacement on the trail should be ready at hand.

Also, I plan to change the front so that it only has one hose going down to the axle, than hard line on the axle with two smaller hose at the knuckles.  This will put everything in a much safer stop than it is right now, and it will be much cheaper to replace, and simply work on. Anyone who has worked with AN fittings knows they are much better than inverted flare fittings to work with.

Also, that MCmastercarr part WILL NOT WORK!!!

JIC and AN are not the same.  Jic and an have different threads.  Though they will probably thread together, and may even work I wouldn't want to stake my life (brakes) on it.  I also believe that th AN fittings have a 45 deg flare compared to a 37deg flare on the JIC.

I believe you are correct

[Phazertwo [OP]]

From my research a JIC and AN fitting are the same.  A AN fitting stands for "air force and navy fitting" and they are manufactured to a higher tolerance, but other than that, they are the same.  They are both 37 degree fittings, I have a collection of both from many different projects, and once I let them float around in the same bin, I can't tell the difference.  The difference between a 45 degree fitting, and 37 degree fitting is quite a bit, and I think it would be hard for me to mistake them as the same.

if you scroll down on this page to "Flared fitting type", mcmaster-carr gives you the choice of AN or JIC when searching for "37 degree fitting", also stating that the AN is simply a tighter tolerance.   They also mention a fitting that is not good for higher pressure that is a 45 degree fitting, is this what you are thinking of?

From the table on this sheet, you can see that a AN 4 has the same threads as the JIC fitting that I linked above.

This is what I have found, however if you did find something that says otherwise PLEASE post it up so that I can see it for myself, if what you say is true, than I would really like to see where you found your info, for my own safety.

This is what I was thinking of. Looks like you have done plenty of research on this. I think you will be fine.

So, I have done a little more searching since I found out that the Mcmastercarr fitting won't work.

Here is what I really need. This website is also a good place to get AN lines from.

The fitting that fits a Toyota is the M10x1 Japanese.

Here is the brake hose that I plan on running.
http://www.speedwaymotors.com/KEVLAR-BRAKE-LINES,5698.html


To get a price you have to select a size.  The AN4 that I plan on running is only $13 for a 12in which I plan on running from the axle to the calipers, and than a 18in or 22in, that is $17 or less, line from the axle to the frame.

After going over everything that I need, it would not be cheaper than break lines from marlin.  However still nifty.
