A good interim fix would be to use sections of 1/2" air hose, or other reinforced hose, around the brake hose, so the rubbing will happen on that rather than the brake line itself. Cut and slit the reinforced hose lengthwise, slip it over the brake hose, and ziptie it in place. It is crude, but effective, until y'all can afford the braided steel stuff.

Crude, maybe. It will work though. Thanks for the tip.

Flex lines crimped

Hi - I got a reply from Airstream - they've agreed to send me 4 new flex lines! But are unwilling to admit that there might be a problem with their design. They say they've sent my photos and complaint on to their "Safety" division.

So I still have to figure out how to reroute the lines so that they are safe. Someone here mentioned maybe putting 1/2" rubber piping around the flex hoses, but unfortunately half the problem is rubbing, and the other half is crimping, so that solution might make the crimping worse.

I bought a 90 dgr elbow yesterday, so I'll try to take a wheel off this week and see whether it might help. And I'll take plenty of photos as I'm going along.

Sorry, my trailer is a '07 (not a '06). But I assume this problem pertains to any recent Classic trailer with disc brakes.

Trvler,
Thanks, I anxiously await your progress pictures as I am going to have to do the same thing very soon as our first outing with the '06 is rapidly approaching.

Exclamation Removed Brake Lines

Well the rain held off and I was able to get the trailer out of the orchard and into the driveway. I then proceeded to jack her up and remove the tires so I could get at the brake lines. Tomorrow I am going to take the lines to a hydraulic shop in the area and get longer steel braided hoses custom made.

Here are some interesting pictures of the event.

This is a picture of how the road side front hose was rubbing the plastic wheel well.



Here is a blurry picture where you can see how bad the road side front hose was kinked.



Here you can see where the road side rear hose was riding and rubbing under the frame and wheel well.



Here you can also see where the curb side rear hose was riding and rubbing on the frame and wheel well.

I was able to reposition the curb side rear hose so it will not ride or rub under the frame or wheel well. The only problem is it is still to short. As soon as I let the trailer down off the jack it makes the bend in the hose a little tighter than I would like to see it.



Here you can see the curb side front hose that I replaced in the campground last year that started this thread. It is still out of harms way, but I am going to replace it anyway.



This is a pucture of both the road side hoses where you can see the harsh bend they make going into the calipers and the damage caused by rubbing on the frame and wheel well.



When I get the new hoses I will install them, take pictures, post the final outcome.

I urge everybody that has an Airstream with the electric hydraulic brakes to inspect their lines and get them replaced as necessary. Don't just look at them, get your hands on them and feel for any spots where they may be rubbing agains something they aren't supposed to be rubbing against.

Those lines look exactly like mine (including the hole in one of them!). I jacked up my 31' as well, and now in the process of figuring out how to reroute the lines such that the flex hose originates on the 3" rubberized axle on each wheel. That way the hose can be further out toward the wheel, and flexes along the radius of the wheel motion (rather than getting pulled by the wheel the way it is set-up now). I will try to post some images when I get one wheel done.

Also thought of a cheap, simple way to improve the problem without changing the course of the lines - go get a rubber doorstop and glue it to the inside frame to produce a ramp along which the flex line rubs. You might have to build it up some to meet the plasticized part of the frame which is crimping the hoses. This should redirect the flex hose away from the undersurface of the frame - you'll still have to worry about wear, but shouldn't be as severe as rubbing up against the metal edge of the frame. Just make sure that the doorstop is flush with the frame so that the hose can't get caught in a gap.

Gotta get back to work!

Custom Brake Hoses

Well my friendly neighborhood hydraulic shop called me yesterday to let me know my new brake hoses were finished. So on my way home from work tonight I stopped and picked them up. I had them made 6" longer and out of braided steel.

I would have started installing them, but it finally stopped raining here and I needed to cut the grass before it needed to be baled. I will post more pictures of the install process and final outcome.

Finished brake revision

Hi - I finally finished rerouting the brake lines, then bled them (took forever) and tested it all with an overnight this weekend. Works well, and the lines are mostly clear (the front curbside nipple at the caliper is just shy of the lip of the frame!).

Here are some photos I took of the process. Hope they make it clear. I fashioned new flex line brackets from 1.5 " aluminum angle, and fastened these to the 3inch rubberized axle. These brackets were angled slightly to direct the flex line laterally past the offending frame. The rigid brake lines I bought at Canadian Tire (very cheap), and bent them with a bender ($10).

I fastened the rigid lines to the frame with rubber and rivets.

If anyone needs more detail, I'd be happy to post more.

lI lost the road side lead wheel interior break pad. (The retaining pad pin was not secured).Result: Total loss of fluid,total loss of trailer breaking capacity,destroyed lead wheel caliper plus rotor. After addressing that problem. I am sitting in Orlando KOA with a non-functioning refrig,a constantly tripping 20 amp AC breaker. 2009 classic 30 in service less than sixty days.Needless to say my first introduction to the AS life style has been less than satisfactory. I reallymiss my previous RV. I forgot to mention my new refrig was also on recall .also

Due to your post I inspected my flex lines and I found one that was almost wore through. But mine was worn on the tire side as though the tire was rubbing it.
Looked like plenty of clearance but I guess not enough. Went to have a hose made today but apparently the fitting on the end that connects to the metal tubing must be different. The new one leaked at that connection but the old one doesn't. Anybody know if there is anything special about the fittings. I am going to order a new line tomorrow from Airstream or Airstream dealer but I am curious if any one knows?

Also Deitz645 thanks for calling this to our attention I would have missed it.

Installed Custom Hoses

On Sunday I took some time off from yard work and opening the pool to install the new custom braided steel brake hoses on our '06. The install was uneventful except for one loose fitting that proceeded to spray me with brake fluid while we were bleeding the brakes. I made sure the fitting was tight and no more leaks. The new hoses are plenty long enough now and I was able to position them so they WILL NOT rub on the wheel well, frame, or tire. Here are some pictures of hoses on the curb side. The road side looked just about the same.

Pappy,
I am glad folks are checking their hoses. If you get the hoses from Airstream I would ask them to send you ones that are 6" longer than the standard hoses. If you have custom hoses made, just take one to the shop and they should be able to duplicate the fittings. Just remember to cover the fittings that hose hooks up to so no insects / spiders try to make a home in them.

For those folks looking for an Airstream part number for the brake hoses, it is...454300-16

Hi I need help with breaks

Not sure if you can help; and truth I need a Bigger truck. I have a 76 airstream I just bought. It is in great condition with the wiring ect./ X retired military man owned. I it hooked to a new Chevy all worked, even electric breaks. I have an 1997 Chevy, Have had problems with the wiring harness. Last year redid all wires to spec, with 6 wires, not 7, but to a 7 way plug. As I also pull a gooseneck horsetrailer. The electric breaks work on the horse trailer/ but not the Airstream? Do I have to have the 7th wire? Wahhh, Been working on it a while and was planing to head to the mountains of nc next weekend. Beth from Bunn NC

So, long story short, I had turned the braking range all the way down to 0 by mistake - turned it up and breaks were there! Glad to know that the breaks were working!

I had a problem with the power jack and Randy from AS was really great and overnighted a part to us also. Every time I have needed AS, they have come through. Sorry to say that the RV dealer in Hendersonville NC (Todds RV) couldn't have cared less.

Is there a retro repair to keep your brake line from rubbing and leaking again?
