I installed these and am seeing wear on the lines. It is where the line goes into the front bracket, at the bottom of the spring base, the ABS wire mount. Is there a better way to mount these so as to not destroy the sheathing and braiding inside?

Answer 1

Yes, this is a known issue with certain aftermarket stainless-braided brake line installations on the JL platform. Because stainless steel lines are stiffer than factory rubber hoses and the factory ABS/bracket opening can introduce sharp edges or tight angles during suspension travel, rubbing and fraying can occur right at that transition point.

To stop the wear and secure the lines safely, you can use a few effective approaches:
Rubber Isolators or P-Clamps: Slide a piece of split rubber vacuum line, a rubber grommet, or a cushioned rubber P-clamp over the brake line right where it passes through the bracket. This acts as a buffer, absorbing the friction and preventing the metal bracket from cutting into the outer sheathing and steel braid.
Adjust Line Twist: Loosening the banjo fitting or hard-line fitting slightly to rotate the line can often eliminate a tight pinch point or unnatural twist, allowing the line to sit more naturally through the bracket opening without rubbing.
Alternative Anchors: If the factory bracket geometry continues to cause friction through articulation, many Jeep owners switch to a universal sliding brake line anchor kit (such as those made by Teraflex) that uses a polyurethane clamp to hold the line firmly without pinching or sharp metal-on-braid contact.

If the inner Teflon liner of the hose has already been exposed or damaged, it is safest to replace that line immediately to maintain reliable braking pressure.
