Grimm Offroad Rear Brake Line Kit
JL
Features & Product Details
Grimm OffRoad’s stainless steel braided rear brake lines can be used for stock or lifted Jeep JL Wranglers and offer improved brake pedal feel by eliminating brake line expansion common with rubber brake lines. DOT compliant and made in the USA, they include the axle mounting brackets to secure the lines. A UV protective black PVC cover protects the brake lines from wear.

REVIEWS & CUSTOMER MEDIA
Great upgrade over OEM, I installed these Grimm brake lines both front and rear! Even though the OEM's are long, these are slightly longer. Very high quality and come with the mounting bracket for OEM like routing. After installing, make sure to bleed the brakes properly and take your time to get all the air bubbles out. This is an excellent opportunity to flush out all the old fluid....siphon out all old fluid from the reservoir, refill with new fluid, start bleeding and make sure the reservoir does not run low. After my initial test drive, I immediately noticed that the pedal felt a lot more firm, it felt spongy before. I'm very happy with my purchase!

As another reviewer mentioned, these are basically the same length as stock....maybe an inch longer. I'll be replacing these with something else eventually.

2021 JLU Rubicon, 3" lift These are the exact same length as the stock brake lines. The quality is better most likely but I bought a different pair from a different manufacturer that are actually longer.

Like the Synergy rear brake lines these don't fit XR/392 rear calipers correctly as the mounting hole for the banjo bolt is rotated 90° from the stock axle calipers. Synergy has told me that they are producing a new part to solve this issue.

The factory brake lines on the JL Rubicon were just long enough for my additional lift but they were terribly soft and it felt like most of my brake pedal travel was spent swelling the lines. Pulled them off, slapped on these Grimm lines, did a bleed and the pedal feels stiffer already. Plus, the lines are long enough for full suspension travel without risk of tight bends. The instructions were 100% and easy to follow.
