This is a pic of all the parts you should get with each of your new Crown or Currie Rock Jock stainless steel extended brake line kits. Take some time to make sure you have all the parts shown as well as all the tools listed on the left prior to starting this project. |
Rear End Installation
|
 |
 |
 |
| 1. Open up your hood so that you can keep an eye on the master cylinder and then place an oil catch pan underneath your Jeep JK Wrangler’s driver side rear brake caliper. Then, using a 15mm socket, remove the banjo bolt securing your brake line to it. |
2. Remove the banjo bolt from the brake hose, remove the copper washers and then set it aside for now as you will need to reuse this bolt. Try to hang or position the loose brake line end up to help minimize the amount of brake fluid that will leak out. |
3. Using a 10mm socket, loosely reattach your Jeep JK Wrangler brake line back onto the frame rails as it will help you separate the hard line from it. |
 |
 |
 |
| 4. Using an 11mm wrench, separate your Jeep JK Wrangler’s hard line from the bracket/hose. Then, using a 10mm socket, remove the bolt securing the bracket/hose to the frame rail. Set aside the bolt for later use but the hose can be discarded. |
5. Slip one of the new copper crush washers that should come with your new stainless steel brake lines on to the factory banjo bolt you removed earlier. |
6. Insert the factory banjo bolt with copper crush washer on through the new stainless steel brake line (be mindful that the elbow of the hard line needs to extend towards the back) and then slip on another copper crush washer as shown in this pic. |
 |
7. Using a 15mm socket, secure your new stainless steel break line to the break caliper on your Jeep JK Wrangler making sure that the hard line elbow extends out and back (as opposed to up, then out) as shown in this pic. Be VERY CAREFUL to only tighten the banjo bolt to 276 in. lbs. of torque. This is a very delicate bolt and can break easily if too much force is applied. |
 |
 |
 |
| 8. Use a 10mm socket to secure your new stainless steel brake line mounting brackets to your Jeep JK Wrangler’s frame rails using the factory bolts. |
9. Slip your new stainless steel brake line up through the new mounting bracket and then fasten your Jeep JK Wrangler’s factory hard line to it using a 12mm and 17mm wrench. |
10. Secure your new stainless steel brake line to the mounting bracket using the retaining clip provided with the kit. |
| 11. Check the fluid level in your master cylinder, fill as needed and then repeat these steps on the passenger side of your Jeep JK Wrangler. |
Front End Installation
|
 |
 |
 |
| 1. Begin the installation of your new stainless steel brake lines by cutting the thin support tie holding your passenger side brake line and ABS line together as shown in this pic. |
2. Use a pair of pliers to carefully separate the main plastic coupling holding your brake line and ABS lines together. |
3. Using an 11mm wrench, separate your Jeep JK Wrangler’s hard line from the bracket/hose. Then, using a 10mm socket, remove the bolt securing the bracket/hose to the frame rail. Set aside the bolt for later use but the hose can be discarded. |

8. Insert the factory banjo bolt with copper crush washer on through the new stainless steel brake line (be mindful that the elbow of the hard line needs to extend towards the back) and then slip on another copper crush washer as shown in this pic. |
9.

 |
| 10. Secure your new stainless steel brake line to the mounting bracket using the retaining clip provided with the kit. |
11. Reattach your new stainless steel brake line and ABS wiring together using the factory main plastic coupler. |
12. For additional support, zip-tie your new stainless steel brake line and ABS together as they were before. |
| 13. Check the fluid level in your master cylinder, fill as needed and then repeat these steps on the driver side of your Jeep JK Wrangler.
14. You will need to bleed your Jeep JK Wrangler’s brake system before you can drive it. Click on the link below to see a detailed write-up on how to do this:
Jeep JK Wrangler Brake Bleeding Write-Up
|
That’s all there is to it, you now have a set of Crown or Currie Enterprises stainless steel extended brake lines on your Jeep JK Wrangler and one less thing to worry about when you’re flexing on the trail. Please let me know if you have any questions. |
actually a very helpful write-up.
a brake pad change would be good and or a E-brake adjustment..
lol!! an e-brake adjustment is on its way and i will try to do a brake pad change as well as soon as i can.
Hi Wayoflife,
If you could quickly give me your opinion on this please: I recently installed an OME kit on my 2dr and like most other JKs with the OME kit I actually got about 3″ of lift. Now, the guy at the ARB store who installed it told me brake line extention aren’t required and that they won’t break etc with an OME lift - but in the same breath told me he wanted brake line extentions on his JK with OME’s. WIth what is written above I’m having some doubts especially since the lines look pretty tight even on a flat. Have you heard about other OME’ers that installed extended brake lines?
Thank you
WOL,
you state,
“If you’ve just lifted your Jeep JK Wrangler 3″ or more (or are planning to do so), you will need to do one of the following: A) Install a set of rear brake line extension brackets or B) Install a set of stainless steel extended brake lines…”
Do you find that front extended brake lines are not necessary? I have the Teraflex 2.5″ HD budget boost, which has the 3″ coils up front and found that the rear brake lines are too short when the rear is flexed; I haven’t had the opportunity to check the front yet (I hope to do it tomorrow). Any help would be appreciated.
hi louis, i have installed an OME kit and can tell you that the shock lenght were just long enough to prevent the over extension of your brake lines. unless you installed shocks other than OME, you should be fine.
silver rubicon, did you install the brake line drop brackets?
wol,
yes, i have installed the drop bracket. when flexed, the rear brake line is stretched; but no one else has indicated a problem on the site, so maybe the droop is just enough to stretch out the line but not enough to break it….
Louis,
I installed the 2″ OME kit with OME shocks and the rear lines were very tight when flexed so I changed the rear ones. The front’s aren’t as bad and I’ve had it flexed many times with no issues so far. See pic: http://good-times.webshots.com/photo/2761039850102055478bvkaHe
