I wasn't suggesting streamlining the line was going to give a noticeable change in speed, I was only suggesting that would be a good measure of a clean installation. But I guess we could also just leave old antennas installed, and forget about fairings, and cleaning/waxing and all those other unnecessary draggy things too, after all, it's only a square-of-velocity penalty. (Green airplanes might not benefit anyway.)
When I bought my 170 it's brakelines drooped down toward the ground and then made a 90-degree bend outward to the caliper. )see the pic below..look at the left brakeline contrasted against the dead grass.) It was UHG-GUH-LEY. And the drooping brakelines posed a hazard on turf strips as the flexible line could be hit by high grass and pull the soft aluminum tubing out of position (it being held only by the spring-clip to the gearleg.)

George you must have just visited with my newest A model. Can't say it's ever been washed except for rain, has no fairings, has 6 antennas or the remanents of them. But as you say it's green so it doesn't know how to fly slow.

If you think thats little flex hose loop is bad, I better get new shorter lines on mine before convention or I'll never hear the end of it.
I'll take pictures of the crosswind gear and I have a movie of it in action which I haven't posted because I want to make a better movie first.

George, Your old brake lines look like mine and your new lines look like what I had in mind. But it's not the GRASS I worry about, it's the SAGE BRUSH. I vividly remember ripping one off my 140 on a very short strip, talk about pucker power!

According to Hill Aircraft, you may have difficulty finding it because it refers to a superceded part number. YOu can order it by description "fairing" or by "extrusion":

I am in the process of turning my brakes around to the back side of the gear leg and as part of this project I made new lines. Looking at the IPC it shows a hard line to the caliper. I thought this was odd but that is what I made. Now I find this posting, that's what I get for doing my research after the work, and it looks like most people have a flex line at the caliper end. My question is has anyone had an issue with the lines cracking due to the flexing of the gear leg and how any of any have the hard line the full length.
I haven't gone to far yet so I may make the flex line before any reads this. I would like to hear what people have to say anyway.
I had hard lines all the way to the caliper and was having issues with the line holding the caliper away from the disc on one side. I would have to pump the brakes a couple of times to "re-seat" the caliper before the brake on the left side of the plane would work. No cracks in the lines, however. At my last annual I had my IA install flexible lines to the caliper. Actually, he said he installed recently removed stainless fuel lines from a 421 as my brake lines! They work and look great! I'll show pics next time I get to the hangar. May be a few days as we're still getting a pretty good "dusting" of 6-8 inches of snow here in NC!
