Alright, today on This Old Trailer, what we are going to do is install electric brakes. Right now this trailer does not have any brakes on it whatsoever, so it has two drag axles. So the first thing that we need to do is go ahead and take off the rear wheels. And then we will go ahead and take off the hubs. At this point we will take off the dust cap on our axle. And basically what you want to do is on this particular unit we have an E-Z Lube cap, so it fits kind of tight. It is a good idea to go ahead and rotate the hub and lightly strike it and then I will just back it off with a screw driver behind the flange. And then pry it off. Alright, let us wipe off the excess grease on the end of the spindle here and we will get to our tang washer. And we will release it so we can back off the castle nut. Alright, we have it cleaned up a little bit. Now right here, this is the tab I was talking about. That is our tang washer. Take this. Push it down flat to the flat spot on our spindle and then you can take the castle nut off. 1:07
Alright, at this point we can go ahead and just remove the entire hub assembly. Alright, now we can go ahead and clean up the spindle so we can have a nice clean area to work with. And then we will start reassembly. Alright, now that we have everything out of the way we can see what is going on. What is going to happen is our backing plate is going to bolt on to this square flange right here with the four holes. Now, if your axle does not have that, what you need to do is get one of these flanges and have it welded on to your axle. Alright, one thing that we need to prepare is the backing plate. We will go ahead and pull the wires up and out of the way and we will route them through the plastic holder. That will keep them safe and out of the way so that they do not get jambed up between the flange and the backing plate itself. Then we will go ahead and install it on the flange. Two things that we want to remember is that the magnet always points towards the ground and, as you can see, the arm that the magnet is connected to, that bow always faces forward. 2:03
And then on the backside we will go ahead and install lock washers and nuts to put everything into place. Okay, let us go ahead and get our hub ready. I will take a finger full of grease and start off by putting it in the race. And then next we will go ahead and our bearing into the packer. You can do this by hand our use a device like we are using here. Pack the bearing full of grease. And then what will happen next is we will go ahead and the bearing inside there and then we will install the seal. In this instance, we actually have an E-Z Lube spindle. So, when we are done with this, we can actually add more grease. Basically, add as much grease as you can to the inside of the hub. If you do not have an E-Z Lube spindle, then just pack it as normal. Alright, at this point here you can actually use a special tool that distributes the force of installing it. Most people do not have this at home, so we are going to use a regular mallet and just lightly tap it in a circle until we get it even all of the way around. You can tell by the tone that you have it all of the way in there and flat. 3:08
Now we will go ahead and flip it over. And go ahead and do the same thing to the races and bearing. With that settled, we will just put a thin film of grease on the spindle and we will go ahead and reinstall the hub. Next we will go ahead and add the flat washer, then the tang washer and then the nut. When we tighten down the nut, what we want to do is run it up as far as we can with the tool. And back it on and off a few times, make sure the hub if fully seated. And then we will go ahead and tighten up the nut until it stops and then we will use whatever tab lines up with the nearest notch in the castle nut. Whichever tab you use, or notch, what you want to do is you do not want to tighten it to use the next one. You want to back it off to use the nearest one. That way, you do not over tighten the bearings. When they get extra pressure on them, they will get hot and wear out faster. And once we have that resolved, we will go ahead and push up the tab back into place. 4:23
Alright, the next thing that we are going to do is go ahead and adjust the brakes. And how we are going to do that is basically we are going to tighten up the brakes while rotating the hub until they just stop. When you can not rotate the hub by hand anymore, then we will go ahead and back it off ten clicks. And then check to see how much drag we have. The end result is we should have a very slight drag on the brakes on the hub. Now, ten clicks will get you pretty close to where you need to be. You may have to adjust it in or out depending on how much drag you get. Alright, we will go ahead and replace the caps on the back side of the backing plate. Then we will go back over to the other side of the axle and repeat the same process. And our next step would be to go ahead and put on the dust caps back on the end of the hubs. And we will just tap them into place. And there are a variety of different methods that you can do that with. We actually use a 2 inch conduit coupling. That actually works great on these types of dust caps. Okay, we have finished our installation of the backing plates and the hubs. And next time on This Old Trailer we will start next on the wiring components.

The magnets on my horse trailer brakes were weak and worn. I found THE ENTIRE BRAKE ASSEMBLY, MAGNET INCLUDED, on etrailer dot com for less than the local RV parts desk wanted for a single magnet! No messing with clips, springs or wire routing. Just R&R four nuts holding the assembly to the spindle, a few flips of the brake adjustment spoon and DONE! Outstanding value! AND... ...the assemblies are MADE IN THE USA! Thanks, etrailer!17704

Complete and direct replacement and easy install. If I had a complaint, it would be simply that the adjuster plugs weren't included but not a big deal. 81425

I have a trailer with older Kelsey-Hayes axles, and was having trouble figuring out what brakes would be suitable replacements. Then I came across e-trailer, and found the info I was looking for. I was more than pleased to find that these Dexter brakes would fit, and the price made the deal even better! Thanks for such great information and service. I will look at e-trailer first for future needs.81154

The product was as advertised or better and shipping was great. They showed up sooner then I expected and just ahead of a nasty storm with heavy snow and high winds which I was afraid was going to delay the shipment until the following week- Kudos to UPS! Was able to track them all the way. Didnt get any pictures but they were an easy bolt on- much better than replacing the brake shoes and magnet separately. Also you cant beat Dexter Made in the USA quality. Thanks again....Walter Hagen 77056

I completely rebuilt my trailer. The brake assemblies ordered were easy to install. It was much easier than trying to rebuild my existing brakes. The instructional videos from etrailer.com made the installation of the breakaway kit a breeze. Shipping was upgraded for free and received my order very quickly. It was a pleasure doing business with etrailer.com.59994

The brake assembly was identical replacement and was very easy to install. All that's needed is to remove 4 bolts and the 12v brake line. Much easier going this route instead of trying to individually replace the shoes and magnet. This was for my travel trailer camper which has Dexter 3500lb axles. 46791

Product was as advertised. Form, fit and function were excellant. Assembly was a breeze, especially with the non-polarity of the wires. Just bolt them on, plug them in, adjust them, and go. Recommend buyers also purchase the 4 nuts that hold each backing plate onto the trailer's mounting flange. They do not come with the assemblies, and 7/16 x 20 (fine thread) nuts are getting difficult to come by. I went to my local Lowes to purchase 16 nuts and lock washers for the 4 assemblies I purchased.. They only had 17 nuts in the entire store.42572

Made in the USA. Easily bolted on, but there were no supplied nuts/lock washers and I wish the bolts were a tad bit longer. etrailer prices and shipping were awesome though this order of backing plates/hubs/drums were not packed as well as the others. No worries, it got here without issue and is on trailer about an hour later!. Thanks again etrailer!41577

An unbeatable value over buying any single or multiple parts of the brake system for trailers. Everything being assembled and properly lubed by the factory makes this a no-brainer for doing any brake maintenance. Without knowing any of the prior history of the new-to-me trailer, I have more confidence now knowing that I have good brakes backing me up. I would highly recommend this assembly over just getting individual parts. I was also happy to see the "Made in the USA" sticker inside each brake assembly!41253

Purchased the entire brake and hub assemblies for about the same price as a brake job at the trailer shop. Shipped quickly...etrailer even upgraded my shipping at N/C. The brake assembly and hubs were simple to install. The brake controller took less than a minute to install. Good prices, great service. Would definitely do business with etrailer again.33579

Great deal! Only cost a few dollars more to replace the backing plate and components than to purchase new shoes. If you're debating whether to replace just the shoes, or the whole backing plate I'd recommend you replace the whole backing plate. It's far easier (4 nuts vs 3 springs and more), and ensures that everything is in good working order. One caveaut, however: it's not easy to replace backing plates when the nuts are severely rusted (in my case, it took cutting most of them off). FYI, I'm using these with drums marked "8-249-07" NOTE: You'll need (4) 7/16-20 nuts if you're not planning on using the originals. Bolts are included.30304
