Yeah, I had to tap out the calipers to 1/8 NPT but is easy to do. Use a little grease to keep the chips out of the calipers. Have only had 2 failures, one from a huge rock smacking it which I believe would have clobbered a braided line too. The other I had a line crack right at the fitting on the front caliper during some snow wheeling. It had accumulated a ton of snow there and froze and cracked the line. Took about 3 minutes to cut and re-attach the line and off we were going again. I may use braided line on the axle ends sometime because of that freezing break. I too ordered some extra line since the kit didn't have enough for my individual runs for the rear cutting brakes and the other stuff I got was a thicker wall tubing. I also started using inserts in the line and the ones I have only fit the thinner/larger ID line. From my understanding this line is essentially what is inside a braided line and the braided mostly protects from external damage.
