Whew been working a lot of nights to get her ready as we are going to be out of our house soon. Might be towing the trailer over to the county dump to use their scales today time permitting. Curious what she weighs in at as an aluminum tent.

It's official she is an aluminum tent! Well mostly . All skins in minus the center overhead and the endcaps. Those will be stored in the trailer for the cross county drive and I will reattack once things settle down. All outlets are installed and functioning including the 4 new additional outlets I added over the stock setup.

Time permitting I would like to get the converter and DC breaker panel is so I could have the Fantastic Vents and add in a few of my new LED overhead lights for convenience, but none of that is necessary for our 2000 mi tow to San Diego.

Aired the Goodyear marathons to 55 psi cold, they are rated to 65 max but being so light I figured maybe 55 would add a little cushion?

Still have to adjust my Tek brake controller on the maiden tow to the dump. Any tips on that? I recall that you are supposed to increase the setting till when you manually activate the brakes the trailer tires lock, then back off off slightly. Does everyone do that? Sounds a little sketchy to me.

Yes adjust to lock then back off a tad. If you have a proportional brake controller they will probably never see 100% again. You are setting the worst case with the locking test. Sometime one wheel will lock before the others which is a real pain. This can ruin a tire if it keeps up for long. It is also hard to tell which tire is locking sometimes. This would be the advantage of using disk brakes.

Getting ready for a long road trip soon. Wish you the best of luck. It might be a while before you have time to continue the project. You've got a lot done!

Millertime's rear bathroom rot '76 Tradewind thread

Thanks David, best of luck to you too.

I took the trailer out for its maiden voyage and it weigh it. With the trailer axles only on the scale HITCHED she was 2820 lbs, so with tongue weight just around 3200 I would guess.

Question for the group, brand new axles and brakes, I manually activated the brakes at various speeds up to 35-40 mph and increased the to near max and while I could feel the trailer slowing I had all windows down I never heard the tires lock. One person I asked said the brakes needed to be bedded in. Seems reasonable to me, but if am just wondering if with new brakes this is common/uncommon. If I have a wiring issue (bad ground or something) I need to figure it out now.

Hi MillertimeUS, My new axles are 10"drums with the six bolt pattern. I was told that was the new standard for "lightweight" trailers. Geez, four 10" heaters on a 4000 pound trailer seemed plenty adequate for long Colorado downhills. The first test I did was jack the trailer up, pull the emergency brake safety pin, and rotate the wheel/tire to feel the brakes lock up. They did, so I figured I have adequate voltage to the magnets.

My Ford factory brake controller is set for my 86. When I tested my 66 Trade Wind, I got some braking action, but not a wheel lock up. I've been a bit disappointed in the braking action of my new 10" drums. I have not tried to set up the gain on my brake controller yet. It was 8.5 to lock up the 86, so I assumed that was enough power to handle the 66. But maybe not.

Bottom line, try more gain setting on your controller. At 20 mph a full actuation of the in cab trailer brake controller ought to stop the trailer and tow vehicle with some tire squeal without using tow vehicle brakes at all. Mine doesn't do that yet.

David

I have never seen trailer drum brakes that would stop both the trailer and the tow vehicle in less than half a mile. Now maybe with disk brakes you would have better performance.

Yeah, I've had both 10" and 12" brakes that didn't do squat for the first 100 miles before finally coming on board. Use them a bit, readjust the brakes then use them some more. I have 10" brakes on my Overlander and they really stop well. I like to feel the trailer pulling when I stop, I guess I'm used to the 34' with a Hensley hitch where ya really want it to be agressive on the braking.

Thanks all, making me feel a little better. Will let them work for a bit and recheck after 100 miles.

Perry are you saying it is possible that even at 3200 lbs 4 new 10" drums may not lock up the tires even once broken in?

Millertime's rear bathroom rot '76 Tradewind thread

Once the shoes are worn into the drum they will work well.

It just takes a few hundred miles.

If the rest of your electric brake setup is right, I will make you the promise that after they wear in, you will be able to lock those wheels down and make smoke.

It took me the the best part of a thousand mile trip before my brakes to fully settle in.

I am a person who likes to feel his trailer brakes a lot. I work them hard. Like I said above, if the rest of your setup is right, the 10" drums will work just fine once they wear in.

When they start wearing in they are going to piss you off as they start locking up because you will have the gain turned up all the way.

See what it does on a dirt surface

Get the trailer moving slowly on a dirt/weeds (but not someone's lawn) surface, then apply full brakes with the lever on the controller. If that locks the brakes, you'll leave tracks. Pull the trailer forward a little, shut down, then get out and evaluate the tracks.

A good, symmetrical set of skid marks says the brakes are working (or at least that the failure is on both sides. Full application of the controller should lock them up on dirt. Easier on the tires than locking them up on pavement. Our trailer is single-axle, so I have no experience evaluating tracks from dual wheels/brakes. I assume there would be a difference if one brake on a side were not working.

You can jack up one side of the trailer, spin a wheel by hand, and ask a helper to activate the brake controller. That's how we tested one wheel at a time. With no load on the wheel, it should stop instantly.

Great work on your trailer in such a short period of time. Best of luck with the move.

I read through this whole thread today. Great work on your trailer!
Since you sent that PM to me I took time to look at your frame. The bike rack I have will not work on your trailer without being modified.

The brakes will perform differently at different speeds. I think they work the best about about 25 MPH. Yes you should be able to get them to lock once they are broken in. Good car/truck radials will also grip better than most trailer tires. Stopping the trailer with the trailer brakes only is a little like trying to stop a car with just the emergency brake. It works but it takes a while. Once they lock, the frictional force is lower than if they don't hence the reason for antilock brakes. Brakes on the trailer tend to make it more stable and less likely to jackknife during braking. You have to play with that brake controller as they brake in.

So where is your new duty station?

Thanks all! Some great advice here, love these forums.

AWWarn yes unfortunately I don't think it will work either, did you do the work yourself? Looks great!

Perry we are headed to San Diego, will be stationed aboard a ship at 32nd street. We are excited for sure to spend some time out there.

Yes, I cut it out with the plasma cutter and welded it up with a wire welder. I'm lucky to have a relative with a welding shop I can use when I need to.
