Topic: whats the real name of this fitting??

[754]

That what I have run, AN 3 and AN 4. Myself I think banjos are for "The Kid from Deliverance"... and am happy to run same adapter as caliper for the line coming straight out.. looks cleaner if your bars permit. Then I used a drilled stem nut on dual disc, and run the line thru the tree to a tee underneath.. cleaner. Use 45 on the tees, expensive but looks proper..

BTW, your hose exit from caliper may require a 45 degee fitting, to look best and clear parts. If it has to touch some slit a piece of clear tubing a few inches long and put that on the hose..

Hey 754 are you sure that th caliper threads are 10mm x 1.25 ? i cant seem to find anywhere that states that. i do have a new MC coming in the mail that i KNOW is 10 x 1.25 and it comes with a banjo bolt so il just check it in the caliper i guess when it gets here.

[754]

First post this page, last paragraph, I said I was guessing at pitch, someone will confirm.

if you dont have a guage, a 10mm is just over 3/8 inch, and 1.25 pitch  metric should fit real close to  bolt with 20 TPI.like 1/2 NF or 1/4 NC

It is 10 x 1.25mm.
 If you don't believe me (or 754) try screwing one of the caliper bolts into brake line hole (the ones that hold the two halves together on swinging calipers)
The bolts are much easier to measure.

sweet, thanks alot guys im guna be ordering this stuff up.   i was also telling goon one of my fathers clients owns a state of the art facility for cuting lenses ( hubble telscop type shiz) they have everything imaginable so he offerd to throw my disc on the bridgeport and drill it and slot it. he told me not to worry, if he destroys it he will make me a new one haha il get pic up after its done

Ok can we/I see some pics of some of the setups you guys have, I will be doing this eventually after I gather all the parts for the dual disc setup. Tygrant I am looking forward to seeing that rotor when you get it done too.

i have been lookin all morning and i cant find a 45 degree 10 x 1.25- an3 or an4 only straight connectors... if you know where i can get one feel free to throw it out there

also i assume an3 and an4 are just differnt brake line sizes or something?

[754]

I did not make it real clear;
first you install the adaptor on say the brake caliper and m/c, now you can fasten AN lines.

 Now the ends on the lines can be straight, 80 or 45 degrees. The last 2 sometines are made of tubing, or forged wich is thicker and way more cost.

 I am talking about lines that I put together, I cut the braided hose and put the ends on... I got the parts from Earls Supply.

2 problem I notice with premade,
They are usually crimped on, sometimes not a clean looking.
Some use tubing as part of the ends(especially on Harley lines).
Lengths are usually in 2 inch increments.

I dont like steel tubing on fittings, simply cause they can be sabotaged easily (kinked by hand) or  bend if line gets caught on something moving bikes around. Sort of defeats having a better system if it still has a weak link.
IMO the only really killer looking brake lines were usually made up by hand and fitted carefuly.

-3 is around 1/4 in dia or 5/16 ish
-4 is around 5/16 in dia or 3/8 ish

Now where this comes into play is your routing, as bend radius becomes smaller on the -3.

Example,

On a stock 73 750 fork I had a tee under the tree, and 2  -4 lines going to dual calipers, and they stuck out past the gaiters, did not look so nice.

Then I went to a tee with -3 lines, but used forged 45 degees fittings coming  off the tee, arcing gracefully to a caliper on each side mounted behind the fork.. much nicer but it cost 3 times as much..

I do have pics, but need a buddy to scan and post.. guess I better go ply him with libations..

Another thing i like about selfmade is, you can shorten a line, or take off the fittings and use them on another line.

[tygrant]

OK, making more sense now im looking for cheapest possible route. i notce z1 has lines in 1 inch increments so i might just order a line from them, but then i run into the problem of putting a 45 degree end on it. im going to check this earls supply you speak of. thanks again, been a big help

[754]

Another combo i did not mention,

sometimes you can thread outlet end of front MC to NPT, I belive they make an NPT to -3 or 4 fitting, might be blue anodized.

You may not want to retap your master cylinder, unless you have a spare... but the stock threads are quite long and you may be able to get both in there (providing sealing face surface did not get too big, for banjo & washer use)

On High bars I have used a 90 coming out the master cylinder, on drag bars I used straight

i would check out Earl's plumbing (not actually house plumbing)    http://www.holley.com/division/Earls.asp

or Russel Performance  http://www.russellperformance.com/

if you have a "speed" shop locally they may have these brands. some place like summit or jegs will most certainly have them available. depending on where you live, they may not be as metric friendly. i know my town is not. you may have a choice between steel or aluminum, so keep that in mind. personally, i am a fan of steel if it has threads. either brand should be able adapt from metric to AN. what i don't know about the calipers is if they are in fact inverted flair. i haven't taken mine apart yet. not necessarily a big deal as far as availability is concerned, but it is critical to know if you want them to seal. with earls you may not need any adapters to AN. i fitted their stainless braided hoses onto my BMW and they require bubble flair. so 10 x 1.25 inverted, or even gasket seat, should not be an issue. i would imagine they would even have banjo to inverted flair in reasonable lengths. i am of the opinion that if you can do this without conversion fittings, that is the way to go. (90 or 45 degree fittings aside.) i am not sure what advantages adapting to AN would have, if it wasn't necessary. and keep in mind you don't necessarily have to look for motorcycle specific hoses, though they may be offered. don;t tell anyone, but my brake hoses are not DOT aproved, but pressure tested to aver 4000psi. *i do not advocate using non-DOT approved parts, or parts intended for off-road use only on street applications. that is my formal disclaimer. good luck with your search. be sure to let us know what you come up with.

later,

We got some pics posted of the brake setup with -3 lines on a dual disc setup.

Look for a thread called 754 pic.. posted by 1080, think it is on page 3
