***UPDATE***
Here's a chart I compiled of potential brake lines to try for the front.  Some of the hoses I know will definitely work whereas others I am unsure
of. I created this list to help speed up the search process for others. Before I did I killed a lot of time going through a brake hose catalog looking 
for potential donors.  I'm not saying all of these hoses will work, you will need to make sure the fittings are appropriate or not. I keep a copy in 
my glove box. I had a SSB hose break once when at an off-road park on a weekend about 30 minutes before the local auto parts store closed. 
I had to buy a tight fitting XJ hose to make the 3 hour trip home. If I had this list I would have had another 10 hoses to try other than YJ that may 
have been stocked by that particular auto parts store.
****END OF UPDATE***
While in the process of doing a WJ brake conversion to my 98 XJ, I knew I would need a set of longer front brake hoses.  I previously had been
using 1995 (YJ) Wrangler rubber hoses.  When performing the WJ brake conversion there are two different replacement calipers to choose from.
The earlier set are manufactured by Teeves and the later is made by Akebono, I chose the Akebono calipers due to Jeep switching to them to
address rotor warping issues on the WJ when using Teeves.
The Akebono calipers (dual piston) are physically larger than my stock XJ calipers (single piston).  Because of this the mounting location for the
brake hose is maybe 3-4 inches lower than the location on the XJ calipers, which eliminates the YJ hose from further service.
Some may say now is a great time to purchase a set of Stainless Steel Braided brake line and I have previously used SSB on my Jeep.
Problem is that I had a brake hose failure off-road when I was just starting to head down a hill.  The wild ride down the hill was enough to
sour me on SSB lines.  Now truth be told the hoses probably wore quicker because of the way I had them cinched away from being chewed
upon by my Swampers, but still the failure after 2-3 years of use was alarming to me.  I did a ton of searching on the Internet to see what
the consensus was on the reliability of SSB lines.  Turns out there was a ton of similar stories that further reinforced my decision to steer
clear of them from now on.  If you choose to run SSB lines then I strongly encourage you to routinely check them for wear and tear and to
replace them every two years, whether they look like they need replacing or not.  
 I hopped onto NAPA's website and began searching for hoses that were longer and with similar fittings.  I first double-checked the Jeep
 models hose lengths to make sure I hadn't overlooked a better solution within the family, as suspected the YJ hoses were the longest
hoses offered as OE from Jeep.  Next I was onto searching through Chevy/Dodge/Ford 1/2-ton trucks both 2wd and 4wd from 1970 to present.  
The list below is largely from going through those parameters.  I did largely ignore 3/4-ton trucks seen as I had a fair number of hoses to
try without including 3/4-ton.  3/4-ton can be somewhat of a grey area when searching through hoses.  The fittings used on brake hoses
can be either in SAE or in metric, so you have to be careful with what you buy.  The other gotcha is that larger vehicles use a larger line,
which is why 3/4-ton trucks can be somewhat of a grey area.  I know most 1-ton trucks definitely use larger diameter brake lines than the
XJ and it wouldn't surprise me if some years of 3/4-ton trucks did as well.  Unfortunately NAPA's website doesn't tell you what the bolt diameter
and thread pitch is so it can be a bit of a crap shoot.  Having said that some of these hoses may be the wrong size for all I know, so don't be
surprised if that happens.  The other bugaboo is that the pictures of the fittings in some cases was cropped so you couldn't see the entire hose
and fitting.  So some of the hoses listed below might be less desirable than the others.
The hose that worked out for me was the 1990 Chevy C1500 1/2-ton 2wd pickup hose.  The hoses are cheap and plentiful so I am ecstatic with the
results.  I hope this chart is helpful for you as well.
