When I put the rear-end part of the Rubicon Express Lift Kit on the Yeti, I noticed that the right-rear brake line had some stripped fittings. The Rubicon Express Lift Kit came with new braided steel brake line for the rear as well as the front. I decided to replace the right rear brake line and replace those fittings. I finally got around to doing that today. I ordered 25 feet of 3/16" steel brake line (with various fittings) from Jegs, along with a flaring tool, pipe cutting tool, and a line bending tool. Here's a pic of some of the items you will need if you are going to replace a brake line. The Sharpie comes in handy during the bending process, for marking exactly where you need to bend.
Here's the right side of the suspension that is missing the brake line. You'll notice the new braided line and junction coupling mounted on the axle.
I needed about 19" of line, so I straightened it out and cut it off with the pipe cutter.
Once you make the cut, there will probably be some burs and you'll need to de-burr the inside and chamfer the outside of the line.
The pipe cutter I bought came with a de-burring attachment at the end of the tool.
One clean end de-burred, chamfered, and shiny.
Insert the brake line into the correct size hole in the flaring tool. Since I'm using 3/16", that's what I'll use. Make sure you tighten both nuts on the flaring bar to hold the brake line firmly in place.
The amount of line material you want sticking out of the flaring bar is exactly the same depth as the flaring adapter. Too much or too little and the line will not flare correctly.
Insert the correct size flaring adapter (in this case I'm using 3/16") into the end of the steel tubing.
Place the anvil over the bar and crank it down until the flaring adapter touches the flaring bar.
