braided brake booster line

[flip3d]

I've seen this on a few cars here. I've searched google/yahoo/zilvia to no avail. I now know everything I need to learn about SS brake lines, though :P

Anyways... What size line would I need and what sort of connectors should I use? Just regular clamps? What's up?

That would be a vacuum hose.

You need to research clamp-on braided hose ends if you want braided lines that badly.

Well, I need to replace my brake booster line so I figured I'd try some braided lines.

I know it's a vacuum hose. I was just wondering what size it is.

Also, I don't understand the sizing of the hose ends.

AN fittings are the number of the fitting divided by 16. -8AN=8/16" or 1/2", -6AN=6/16" or 3/8" etc

I believe that's 1/2" line you'd need... I know my -6an line (3/8") didn't fit. I use the Aeroquip "low pressure" socketless hose for fuel, oil, and my catch can:

... and will probably pick up a length to use as my brake booster vacuum hose too. If I remember, I'll measure it out tomorrow and tell you exactly what you need to buy.

Also, you can use standard hose clamps with this hose, or you can get all pretty with it and use a 'hose clamp cover' like this one from Earls:

Everything is available from Summit, Earl's (anplumbing.com), or your local race shop.

No thanks, thanks, and thanks.

Time to go on a Summit spending spree :P

There is a problem with this thread.

You posted a picture of what appears to be a stainless steel braided line with clamp-on ends.

You then said:

Earl's Econofit Clamp On Hose Ends (http://bakerprecision.com/earls21.htm)


"braided" refers to the construction of the line itself. Not the exterior insulation material.

Braided lines come in a variety of constructions, but generally it refers to the way the fabrice is weaved into braids to give the line strength. The hose ends depend on the type of insulation construction used on the braided line.

If you have a stainless steel insulation material, you will need some sort of fitting that will form a seal from the line to wherever you hook the line to. Obviously a standard hose clamp won't work because the SS insulation doesn't crush-fit.

If you have just standard flexible insulation material, you can use a regular hose clamp because the line is flexible and can be clamped.

If you are using a braided hose that looks and feels like a regular vacuum hose, you need nothing more than a regular hose clamp.

TIP: contact the manufacturer of your line and inquire about the type of clamp they recommend. Sometimes a particular type, e.g. worm-type, ring-type, t-bar type, etc., may be preferred over another because it doesn't damage the insulation material as much.

If you use a fancy SS braided hose, you will need a clamp-on terminal.

As for size, if you're using a non-SS braided line, you need a 5/8" inside diameter (ID) line. Throw a hose clamp over it and be done.

If you're using a SS braided line, you can use whatever size line you want so long as the hose ends are clamp-on -10AN. Most likely you will have to use a -10AN line as well, but you can go bigger or smaller with the line depending on how much your ends can accomodate.

Keep in mind that -10AN or larger lines tend not to be very flexible when you cover them with SS. So beware.


This poster is correct.

The dash Army-Navy (-AN) size refers to the the specified number being divided by 16 to give you the actual size inside diamter in inches.



Do you have any other question?
