I have the stock brake line that goes across my AMC20 axle, and it is a hot mess. It is bent in some places and just looks terrible. What is the best route to replace it? Should I just measure and get a pair of braided hoses to replace it? I don't have a flaring tool, and I don't see an OEM replacement part available. My jeep has a rubicon express lift on it, so it already has the longer braided hose that goes from the frame down to the diff.
 
Other's may differ, but that's exactly what I would do...
 
:agree: Do it yourself would require some special tools and some practice at making a double flare.
 
At most auto parts stores there are double flared brake lines on the shelf cut to lengths, they are not hard to bend either. You might even find an auto parts to make one for you. I have seen pre-bent oem replacements on the net also.
 
I have redone both of my CJs, so I have the tools. It is not hard to do, however you can measure your line and buy that size from a good auto parts store, the bender is cheap. the reason they run the hard lines is so they do not get hurt, do not put flexible lines in their place as both damage can occur and that the longer the length of flexible the mushier the breaks will be. not good
they only put flexible lines where they need them for a reason

Take your old line in with you.
The brake line is leaded steel. Easy to bend. I use my sockets for an aid and bend around the OD of the socket for the radius I want.

I think the only "wrong" answer here is rubber line. You can run braided line wherever you want and not lose pressure. But there's certainly nothing at all wrong with getting line and a bender and a flare tool and doing it that way.

Just make sure that if you have to deal with vehicle inspections in your state. That you use DOT approved braided lines.

Thanks for all the tips guys. Posi, that stuff looks nice. Do you need to flare it like the regular stuff?
 
Yes, for some weird reason I enjoy bending and flaring brake lines.

I have the below flaring tool from eastwood, I've owned is for the past 6-7 years long before this video was made. It's almost impossible to make a bad flare with this tool. Once the tube is cut it takes 30 seconds to make a perfect flare.

yep wrong
they did not start making braided for the looks of the stuff, it is to help prevent the line from expanding, them looking good just helps sales.
solid line is going be better than a long length of stainless braid, not only that but he can reuse his old straps and not have to find ones that would properly fit the stainless
I do not suggest he tries to hold it in there with anything but a proper strap, I have seen a lot of stupid stuff done with brake lines like using tie wraps that rot or get ripped out, using hose clamps that crush the line, and other stuff

remember, the brakes are a essential part of the vehicle that need to be working 100% correct or there will be catastrophic results, we do not just rig them together. we are looking for a way to replace the old lines easily without buying bending tools or a flair tool. buying the pre cut and flared tubing will be the most cost effective way and the easiest overall as it just means a simple couple of bends and reuse existing hardware to get the proper install.

personally, I own a roll of brake line and cut, bend and flare for a perfect fit, but then I usually will replace the entire brake system of a vehicle this old as a matter of safety, they are antiques after all. and who knows what has happened to those lines after so many years. Not only my CJs, but any of my older vehicles after I buy them. Mushy or filed brakes are not an issue I want on the highway when suddenly I have a emergency stop situation.

Thanks for all the info. That looks like a great tool Posi. I'll see what the parts stores have in stock and go from there. Replacing the whole brake line is a good idea Baja.
