Andy,
Great idea for retro disc brakes. Will they be actuated by a servo motor? Would hate to go back to the blended system, like an electrically actuated, vacuum booster over hydraulic type hybrid.

Applying trailer surge brakes ... take your foot off the gas. Or tap the barke pedal.

The towing vehicle will slow down applying the brakes on the trailer. This will stop sway. The amount of speed reduction in the towing vehicle only needs to be ever so slight to activate the trailer brakes. The tongue travel to apply brakes is about 1" to 2 ''. And 2" travel for the tongue the brakes would likely lock up in the trailer. That much braking is not needed.

The set up can be disc or drum.

From experience on my boat and dual axle trailer (with drum brakes on all 4 wheels) which weighs 7500 pounds, I have not had an issue in reverse. The location that I park my trailer I have to push it over a curb in reverse. Both axles will go over the curb to the final location. This is not done at high speed so I do not experience any issues doing this.

I also want to note that I am not a champion of any braking system, and suggest it is more personal prefference of the user. I would also suggest that electric, surge(hydrallic) or air brakes when properly set up are safe.

Action.

Your post of what you do with "SURGE BRAKES" could be misleading to some others who may not know.

Your post is "EXACTLY INCORRECT" when you use electric brakes.

The correct instructions for stopping a sway with electric or disc brakes are:

SLAM ON THE CONTROLLER AND PUNCH THE GAS PEDAL.

Why do you continue to post what boat people do?

This site is for Airstreams, NOT BOATS.

Airstreams don't use surge brakes and never have. Quit adding confusion to those that may accidentally follow your advice.

Andy

Please read the post - it is about surge brakes. Not electric brakes.

Slamming anything and punching anything is pretty violent. I recommed against anything violent!

Whoa, Time Out!
This is my thread and I make the rules.
Be Courteous, both of you , or:
I will call down a Gypsy Curse and ;
your cat will die,
your violin string will snap and leave you disfigured for life,
your wine skins will burst,
your donkey will get a hernia and never pull your rickety cart again
and your wife will desert you
and your daughter will marry a Hungarian.

And if Canavera deletes this post, I will go out to California and spit on his Airstream.

By the way, I dont like surge brakes, AND I do not like electric brakes, but I do like air brakes for the heavy stuff, like my trailer.

WHEW!!!! Must be a Full Moon!

Yep, sure enough, bold as daylight! Let's see, this thread started out as "axles" went to the "paint issues"(chemical makeup) and then to "brakes and the controllers"! This HAS to be a new forum first. Three threads in ONE!!! Let's just take a deep breath and "regroup".


Now for alittle humor Navigator, you're up

1. I don't have a cat
2. I don't play the violin
3. My wine comes from a bottle
4. Though my name is Oscar, I am NOT from south of the border (German and Scot heritage), no offence
5. If my wife leaves it'll be the fact the wine skin DIDN'T HOLD the wine
6. And last but not least, I don't have kids!!!!

Now for brake controllers, check the the next active thread.


Oscar

I'm trying to figure out how to install air brakes on my '59 Tradewind. Does anyone have the dimensions? I'm trying to take dimensions off this photo. Figure I can mount it just forward of the AC shroud.

Markdoane.

No no. Don't mount it by the AC. That will alter the aerodynamics to the extent of causing abnormal tire wear and further causing the need to install leading edge slats, so that you reduce the tongue weight below 4000 pounds, and increase the bumper weight to at least 2500 pounds.

Might be better to install it next to the water tank, as your system will generate enough heat from the excessive friction, that you will need water cooling.

On the other hand, if the maximum air pressure is kept below 2500 psi, you could use a radiator to dissipate the heat, as long as it has at least a 32 square foot surface. You could mount that on the passenger side of the trailer, so that you wouldn't obstruct any on coming traffic. Also don't forget to add clearance lights to the radiator, so that it can be clearly seen in the daylight.

Oh yes, please have one of your axles retract, as soon as you reach V2. Saves wear and tear on the vertical and horizontal stabilizers, and helps the "On-star" reception.

Andy,
If I install the colling radiator per your directions, don't I also need a separator and condensate trap? Could I just drain the condensate into the freshwater tank?
Thanks for the hint about the clearance lights!

Markdoane.

You can run the condensate into the fresh water tank, but first you must do the following.

You must hook 4 six volt batteries in series. The condensate must enter the junction of the second and third batteries.

Then you can attach a plastic hose to the 4th batteries positive terminal, and another plastic hose to the junction of the first and second battery.

The hose from the 4th batteries positive terminal can go to the water tank, through a decompression filter.

The hose from the junction of the first and second battery will have water that was deemed unfit, and therefore separated from the good water.

The theory of operation is that the good parts of the water will flow to the positive side and the bad parts of the water will go to the negative side.

The final test is to pour a glass of water from your faucet and another one from a water bottle in the reefer.

Take the glass of water from the reefer, and drink it.

Take the glass of water from the faucet, and dump it on bare ground. When that water impacts the bare ground, if it creates a dark spot and does not explode, then you know that was the bad stuff, and you should not drink it, except maybe with some 240 proof Kentucky Bourbon.

But you must also make sure that the 240 proof Kentucky bourbon is not labeled "a weapon of mass destruction."

If it's not labeled that way, it's OK to drink, but only if your pushing daisy's.

Andy

My axle experience...

Since this was originally an axle post I thought I should post some information about my axle ordering experience since some of the things I found out were not mentioned in the thread earilier and might have made the process a little less traumatic for me had I known what I know now.

I ordered two complete axle assemblies from Andy at Inland about two weeks ago. He had the ones I needed in local stock so they were shipped to me from S. California rather than from back east (with a savings in overall time too by the way). They came by Yellow Frieght about 1-1/2 weeks after I placed my order. I arranged to pick them up at will-call at the freight depot since I thought that off-loading them at my house might be difficult. The freight depot is only about 10 miiles away and I have a pickup truck so no big deal. I did end up making 3 trips to the depot before I retrieved my axles though. The axles had been mistakenly loaded on the local delivery truck and were not in the warehouse the first time I went there. The second time I was a bit worried by the overall appearance of the axles (dirty and paint scrached here and there) and by the fact that one of the drums sounded a bit too raspy when I tried turning it. So instead of taking delivery I went home and contacted Andy to ask his advice. He suggested that I should take delivery but write on the delivery slip that there was "Possible Internal Damage" and check them out when I got them home. I decided to do that - hence the third trip.

Once I got the axles home and unloaded I pulled off the one drum that seemed a bit raspy to see if everything was OK. There was no sign of any problem internally. No spring had come loose or anything at all obvious. As near as I could tell the magnet that is part of the assembly was just making a bit more noise than it was on the other 3 drums. Since I had no idea that there even was a magnet in the drum I had no idea what to expect about a little noise when I spun the drum at the shipping dock. Had I known I probably would have taken delivery on my second trip.

Regarding the scratches - I would have preferred to receive a set of axles that looked showroom perfect. On the other hand it took me only maybe an hour to clean them up, mask off the areas I didn't want painted and touch up the paint with a can of black Krylon rust preventative paint. The axles now look like what I wanted them to look like originally. The paint that was on them to begin with seemed generally solid and did not wipe off with paint thinner by the way.

I am still not totally convinced that axles should be shipped totally loose like they were but mine seemed to make the journey well enough except for the paint scratches and dirt. I do find it a bit frustrating that something as expensive as a complete set of axles can not be had in showroom perfect condition but I also now understand a bit more why that does not seem to be possible.

I guess the bottom line is that the experience might have been a bit easier for me if my expectations had not been so high to begin with. Also the fact of the matter is that I now have the axles that I needed and all seems well.

New grease caps too...

I forgot to mention that all four of the grease caps on my new set of axles were a bit dented. Andy is graciously sending me a whole new set at no charge.
