Once you start getting above 3" of suspension lift on your TJ, I highly suggest replacing the brake lines with longer, extended brake lines. One option you have is shelling out some money for aftermarket extended "stainless steel" brake lines. However, another option is the readily available Dorman EPDM rubber direct replacement, extended length front and rear center brake hoses (4" longer than stock). No special washers or other parts required.

The part numbers for these extended length front brake hoses were posted by Blaine in another thread.

Rear Center:

Once you're all done, you'll need to bleed your brakes. You'll need a container of DOT3 brake fluid for this. To make bleeding the brakes much easier, I highly recommend one of these vacuum brake bleeding tools. I have one of those tools myself, and it's paid for itself multiple times over. It makes bleeding your brakes so much easier.
 
I have heard of aftermarket braided ones failing ....
I consider the braid to be nothing but decoration on the majority of the replacement brake lines. I'd say its only potential benefit would be protection from possible exterior damage which doesn't happen enough to worry about. OE brake lines use multiple layers to create the strength necessary to withstand the high brake line pressures, they don't need additional help from a braided sheathe. Neither will braide brake lines make brakes more responsive as some claim... OE quality brake lines don't balloon outward from stepping on the brake pedal, that's nothing but an old wive's tale.

These are the multiple layers that are similar to what you get with OE brake lines...

It's a marketing scam that someone started way back when, and it spread like wild fire all throughout the Internet. Now we have to listen to people tell us they 'balloon' since they don't know any better.
 
I've got a caliper sticking or a hose problem in the front, so I am planning to replace both. I saved a link in my favorites for replacing my hoses with Chevy hoses, but the link no longer works. Does anyone have any info on part numbers and/or model of Chevy lines?

Here is the link that no longer works... http://www.universityofjeep.ca/Tech/Brakeline_Upgrade/JeepTJ.htm

Any help would be greatly appreciated. If nothing else, then I'll install the YJ lines. Thanks Chris!

The parts you're looking for are:

NAPA #38620

Those are the Chevy brake lines you're after!

Hmmm, they don't really look much different than the TJ/YJ lines. Do you know why people were using these? Availability?

I haven't the slightest clue other than availability and pricing I suspect. That has got to be it.

Are the fittings on the brake lines on our TJ's metric, or standard? I was thinking that everything was metric, but I could be wrong.

Good question... I don't actually know! I want to assume they are metric, but the bolts are SAE, so I'm not entirely sure.
 
I'm using an 11mm wrench on my brake lines. Also, the fittings on the Chevy parts listed look different than what our fittings are.
