Brake Lines

Mike, I originally used the clamps off an o 360 intake tube. That worked fine for standard gear. One thing I didn't like is that the tabs for the screws were 180 from the brake line. So the brake line would be aft on the tube and the tab would be forward on the tube and stuck out in a way you could snag things. Like skin. With the larger tubed 3-inch gear those had to be made. The brake line is still aft on the tube but the tab is 90° on the inside of the landing gear tube. Steal away!
 
I use stainless firesleeve bands for this.

I have also used these but they are a little harder to fool with. I use the firesleeve tool and carefully cut the tail off with a whiz wheel.

I drill a hole in the floor board if needed and run the brake line from the parking brake valve to the gear leg between the floor and the belly fabric. Installed more than I can remember.
 
My old brake lines used an adel clamp to an adel clamp to secure the lines. The new stainless braided lines are too abrasive to tie to the gear legs so I figured I'll use Griplock Ties with a short hose standoff. Simple and effective, and with the rubber they don't slip, scratch the gear, or get abraded by the hose sheath. Dang nice zip ties, these Griplocks.
 
I also used the fire sleeve clamp, but added this metal line clamp and silicone tape for friction/cushion to clamp against, from Aircraft Spruce, has been on for 10 years:

DAM!! That is a simple, clean, and neat way to do it. Now I am going to have to get me some of the Griplock ties.

motosix, NOW you tell me :) I admire all these small, thoughtful details you've incorporated, which add up to a nice package. It'd be interesting to see something similar for Cessna flat spring gear.

Thanks. cubscout
 
Resurrecting an old thread on exiting brake lines. Has anyone have any experience with or pictures of these covers installed? They certainly aren’t cheep. I’m trying to avoid running new braided -4 lines out the bottom center of the fuselage. It needs to be set up for float and ski changes so running one continuous line isn’t an option. There needs to be an easily accessible union or bulkhead fitting.

Yes, a friend's wife pulled some carbon fiber ones off a set I had. They come out at the gear leg and the grommet for them is shown on the covering drawing. Piper brought them out at the longeron just behind the front gear attach.
 
I think that’s the best place. Have them exit below the longeron on aft side of the fwd gear fitting. I’m betting the above noted cover plate gets thrown away at rebuild because I’ve never seen one. I kind of wish I had an example because for $90 bucks I’d be inclined to make a bunch.
 
One of the benefits of rebuilding 5 unmolested, original Super Cubs. The fair really isn't needed but I like them just because they were original. I think there is a picture in one of the Annual inspection videos I did.
 
Brake lines, bummer, does anyone have a parts list for making their own brake lines? $146 for a 14 inch brake line is ridiculous! I had a hose shop make new lines for me a few years ago and today tried to put it on and learned that they used the wrong flare so I am STUCK! Thanks in advance!

37.5 degree flares or Weather head original type? Pictures?
 
had two brake lines made by a hose shop a few years ago with 37 degree fittings (or so they said). Could not get them to stop leaking so called a different hose shop and drove about an hour and a half. Same story but fortunately this time, I did not buy their fittings. They said that I just didn't tighten it enough. Came home, put those hoses back on and really tightened them. No luck, more hydraulic fluid on the floor. Gave up, bought two $147 14 inch hoses from a supplier and son of a gun! No leaks! What a waste of money and time. Thank you for your input and thanks for the tutorial. MK
 
Hydraulics shops use JIC fittings because they’re steel. AN fittings are aluminum. I order AN3 or 4 and get steel fittings on the hoses. I’ve had no issues mixing the two.
 
Perfect fit.
