You're good. I had 4 inches without extended break lines and it was ok. I added them eventually tho just to be on the safe side.

3.5" seems to be the general top end safe zone of stock brake lines.

I was wondering the same thing. I'm at 4" now and should probably put some on. Should I go for yj or just pay for aftermarket stainless lines?

Just do aftermarket, they're not that expensive. Braided steel lines I've heard good things about.

Braided is the way to go

I'm at 1.75" and stock ones didn't reach at all. I'm running slightly extended WB and wj knuckles though. Stock arms they worked ok, aftermarket arms disconnected, barely long enough. Straightening the hardline bends gives you a bit more slack.
I'd buy aftermarket braided SS lines anyway, for both peace-of-mind and durability. Most likely your rubber lines are very old anyways, suprsingly few people replace them.

I have a question about brake lines and abs. i've read you need a drb scanner to bleed brakes on a zj. i have a 97 and my abs no longer works. a buddy of mine/coworker who is always buying and fixing jeeps told me i can bleed them manually and be fine if i ever need to replace a caliper or brake lines, is this true? i hope so i'm thinking about replacing my brake lines just for a peace of mine seeing as at work i've towed a few zj's in the past 2 weeks that had brake lines fail.

It's a lot easier with a DRB tool; you can try to bleed the abs pump "manually", but it is not an accurate method. You either succeed or not.
When replacing calipers or soft lines, fill up brake fluid reservoir over the full limit, and try to work quickly one side & one connection at a time. This way the abs pump won't suck in air and needs not to be bled. When bleeding brakes, make sure fluid reservoir is always close to top mark.
If the pump is no longer functioning and you don't need abs, it can be removed. You need new hard lines from MC to brake proportioning valve, bleed the brakes in a normal fashion and you're done. Remove abs- related fuses and relays.

I am having a hard time with the abs... Fellow I got my zj from ran the mc dry once filled up I bled the brakes but I can't get the rear drums to bleed... The fronts bled just fine though... And my abs light is on...
Does this sound like the mc is bad from running dry or abs problems? And if I do rip the abs out I just remove the unit under the mc all together and run the brake lines direct to the stock mc?
