brake lines

A few days ago i got a wrangler its a 98 sport that had been sitting for 2 years. I had to replace a fuel line, battery, and now i'm working on all the brake lines. (the bent metal that runs along the frame) I know that there are issues with the door handles to. Does anyone have any tips on doing the brake lines they look a little intimidating. thanks
basically i'm looking for advise from anyone who has done this before, should i bend em myself or buy prebent stuff or just hire the job out? thanks again

if you are able to do the bending than go a head. if not get the pre bent ones, they cost a little more but it takes the guess work out of it.

bend the lines yourself, if you can make the flare's yourself. bulk roll of 25' brake line is aruond 20 bux, and you'll need fittings. if you can't do that you can buy straight sections that are already flared and have fittings on them, you'll just need unions to put them together.

don't try to bend them like they did from the factory, its basically not possible. i used to try, its not always possible. do it the way that makes most sense. keep lines away from moving parts and hot exhaust. the only way i do it is to make my own. good luck

I have always had good luck with this. JEGS Brake Line Coil Kits - JEGS
Make sure you get a good quality flaring tool. Last thing you want is to plumb everything and then have a leak at the flair becuase you used a 2.99 special from harbor freight.

i just did my lines.. i used pre bent lines.. make sure there pre bent for your make and year... bending youself is ok but unnecessary bends and over bends can lead to a decrease in brake performance and they wont last as long. i only needed the rear lines running along axels.. ran me 19 dollars through dealer. yours shouldnt cost more than 35.. its the safe and smart way to approach brakes.. they simply screw off and screw on.. bleed system completely and put new fluid in. .. make sure not to bleed on rotors or pads this will cause squeaking.

If your lines are rotted, I assume your system was void of brake fluid in the master cyclinder and air became available to the entire system... Brakes are too important too screw up and the parts are relatively cheap so you don't want to mess around on this job.

If it was me, in addition to the brake lines that were affected, I would replace all major components in the system the air got to (front calipers, rear cyclinders and the master cylinder). Like I said, the parts are cheap and the job is very easy.

Make sure you inspect the flexible lines for cracks and replace them if you have to. New linings (pads and shoes) as well as getting the rotors and drums cut are part of the deal too. Bleed the entire system really good multiple times starting at the farthest line working towards the closest.

Good luck.

It ain't no fun unless you get some of it on you.

This might also be a good time to do the rear disc brake conversion if you have to go that far. If you have a D35 rear find a wrecked ZJ and grab the rear brake components, you'll have to pull the axles to get the backing plate off and on yours too to swap backing plates but then it's fairly simple, plus it uses all jeep parts off the shelf. Use the unknown rear calipers for core on a set of new or rebuilt calipers. Don't forget to grab the emergency brake cables and all that stuff too so you can hook up the EB's.
Here is a step-by-step with pictures and though it is for a D44 the main difference is you won't have to open the backing plate hole for the larger D44 axle shaft, I think he mentions that in there. The biggest problem people have is the EB and finding the parts for it, just grab them from the donor.
