Brake Lines and Pitman Arms Many quality lift kits come with extended brake lines and/or dropped pitman arms. Not too many come with used kits, but if you ask for them, it isn’t too uncommon for the seller to have them lying around. For brake lines, check the overall condition of the outside of the line. Also check the threads for the fittings, and check that where the banjo fitting goes into the flexible line it hasn’t been overly stressed. As for pitman arms, check where the drag link tie-rod end plugs in for signs of wear in the tapered bore. Also check the broached end at the steering box for the same. Look very hard at the entire pitman arm for any cracks at all. If in doubt, walk away—from either the brake lines or the pitman arm. These are parts that aren’t too terribly expensive new, but having them fail while driving the Jeep is the worst thing you’ll ever experience while in the driver’s seat.
