Video Transcript for Dexter Left and Right Electric Trailer Brake Kit Installation

Today we're going to be taking a look at the Dexter Electric Trailer Brake Kit, designed for use with 12 inch brake assemblies and it includes the left and right hand side. Now these brake assemblies are designed to give us excellent stopping power. All it's going to require from our truck is a brake controller. I like electric brakes over hydraulic brakes in utility applications because you don't have to worry about leaks and different stuff like that.These assemblies are going to replace the entire brake kit, so you're not going to have to worry about hardware, your springs being worn out, your magnet being worn out, or not properly connected. By getting a full assembly like this, you can replace absolutely everything, every piece of hardware, you don't have to worry about premature failure. Now in the kit, you'll get a left hand assembly, says it right here, "Left hand," and a right hand assembly.The left hand goes on the driver's side, right hand's going to go on the passenger side, just to give you a heads up.

Also, unlike a lot of other brake assemblies, you're going to have the new hardware to attach the assembly to your axle. I really like that feature. Then of course we'll just have the two wires to connect on the backside, one goes to power, one goes to ground, that energizes our magnet.Now as our hub is spinning around our assembly, once this magnet is energized, it's going to pull. You can see as it pulls on that hub, that's where our expansion comes from, it's going to force our shoes out making contact with the drum, giving us the braking force that we need. Now the magnet, you can see it's going to be a floating magnet, so while it is going to press up against the hub, we're not going to have to worry about it pressing too hard and doing any additional wear that's not normal.Now you can see the brake adjuster right here, this is designed so we can fine tune the braking application.

With any brake tool or screwdriver, you can go in the backside, there's a cutout there, you can see my tool coming in right here, that's going to allow us to adjust whether we need to adjust that for a little more tension. Maybe we got it too tight and we need to relieve a little tension. You can see how that tool's going to work in there.On the left side if we go up like this, that's going to cause our brakes to expand. If we go down, it's going to cause them to contract. Now just to fill you in on the more detailed specifications, the overall diameter of the assembly's going to qualify as a 12 inch brake assembly by two, meaning the pads are two inches wide or the shoes are two inches wide.

This is going to be designed to work with your 14 and a half, 15, and 16 inch rims.Now to begin our replacement process, we're going to need to gather a few simple tools. Basically, we want a dead blow hammer, a pair of channel locks, and needle-nosed pliers. These are really all we're going to need to get this replacement done. The first thing we need to do is get rid of our grease cap here on the end. Generally, we're going to tap outward, you can see that gap starting to increase then it'll pop off.Once that's out of the way, we've got a cotter pin located right here.

Get our cotter pin out of there. Now with our channel locks, we need to get ahold of this large nut here and get it removed. Now as we take this apart, we want to salvage this washer right here, this is our thrust bearing there and that's the only thing that doesn't come with our new drum assembly. We've got new lug nuts, we've got a new cap, new bearings, new seals, this is that one component we want to be sure to hang on to when we put it back together.Now we're just going to start working our hub assembly off. You can see that old bearing, we're going to get rid of that. The brakes are hanging up a little bit, we're going to be replacing those too, so I'm not too worried about, so I'm just using a pry bar just to get them worked off of here. And we'll slide it off. Now as you can see, we've got all the grease off that spindle, got rid of all the old stuff, and this is our time to inspect it.We need to ensure basically that three main areas are in good shape. You got this area here, this is where the inner bearing rides. Nice and smooth, no issue there. Same thing out here where our outer bearing goes. Then right in here on this wider area, you can see where it's real shiny there, that's where our seal is going to ride as it goes around. So we're just going to rub our finger around there and make sure there's no nicks or dents or scratches or anything like that.What happens if we have that here as we fill this with grease, it's going to expand into our brakes and that's not what we want. This one looks really good. If you have any discolored areas where it looks like it got hot, if you have any cracks that are running down through here, or if it looks like it's been turned where the bearings have come apart in there and caused some issues, might be a candidate for replacement rather than just putting on hubs and drums.Now of course to remove our brake assembly, we need to remove the hub that's on the outside of it, the drum assembly. Once we get back into this area, there's going to be two wires that come from our trailer and they run to our brake assembly. We want to get those cut, then we're going to have five nuts to take off. One here, here, here, and here, you can see this one's missing. We're going to try to do a replacement for that, but it has a torsion axle, so we might not be able to, but we do want to get these removed.Once we get those bolts out of there, you can see that's just going to come right off our flange. Now we're going to clean the spindle up a little bit back here. There are going to be centering tabs or centering buttons that come out, you can see there's one right there. Right there on that flat spot, we're using that to center our brake assembly. You can see there's another one right here. I'm going to make sure that this surface is nice and clean and that those tabs are present that way as we put that on there, it'll center it up for us.Then inspect all of my spindles, get everything off and ready to go. Now when we go back on, we always recommend replacing both brake assemblies on an axle. If you have tandem axles, it's a good idea to replace all of your assemblies, but that's not required. You do want them to be at least equal for the axle though. Now with the assemblies, we've got our provided hardware, that's something we don't usually see with some of the competitors. Most of the time you've got to either reuse your old hardware or just pick up some new stuff.Now we want to be sure, remember that line we saw on the other one, we want to be sure our hub's centered on that and we'll use our nine-sixteenths inch socket. We want to snug down our hardware and we can tighten them to specification. Now we've got our assembly torqued, we've got it in place, but now it's time to strip back our wires here coming from the trailer. Now, to add our butt connectors, we just want it stripped back. Butt connectors are going to go in until they stop and we'll crimp those on like that. Same thing on the other side.Now we'll take the wires from our new assemblies . I like to twist these up really well. That's going to go on the other side, doesn't really matter which one goes to which, we're just looking to complete that path. Then we'll pull, make sure they're connected properly. Then to shrink them down we're going to use a heat source. We can use a lighter like we're doing here, we can use a heat gun. You can see they start to turn clear, you can see them shrink down there.Now at this point, you're ready to get your drum put back on. Remember to repack your bearings properly, good idea to replace the seal to make sure you don't have any leakage, and definitely inspect that drum. Make sure you don't have any cracking or any heat spots on it, that can really degrade your braking performance or just ruin it entirely.Now to properly adjust our brakes, we'll want to get our tire rotating, use a brake adjuster tool, we can go in the access port here. See when we're done, we've got a plug, we can plug that up to prevent dirt and stuff from getting in. Now basically when we rotate our tire, we want to hear our brakes making slight contact all the way around. You can see we don't have . or here, we don't have . That sounded good.Go one more click. You can see while our tire still turns freely, we can hear it making contact as it goes around. All right, hearing that contact all the way around is what we're looking for, so we put our cap in here, and we'll get our other ones adjusted.That's going to complete our look at the Dexter Electric Trailer Brake Kit.

Michelle S was great. She contacted me shortly after I ordered some 12x2 brake assemblies. She told me the brakes I ordered were going to take longer to get than expected. She showed me an alternative part. It was slightly more money but I could get it sooner. I got them on time. Thanks Michelle!! 719080

the order arrived in two days from mo. to tx. just what i ordered. From the looks of the brakes I am glad i upgraded to dexter usa made products. Thanks. 782958

Very pleased with the quality of the products and the prompt service from trailer. I am in the process of rebuilding a worn out tandem axle equipment trailer. I will not hesitate to order from you again and I will certainly recommend trailer to others. 778260

I opened up one box and the brake adjuster was loose in the package and the red spring that holds it was missing. I had to use a spring from the old one. The white plastic wire keeper on the backside of the backer plate needs a upgrade. They broke when trying to connect them around the wire. I removed then and filled the holes with rev. Other than that everything went well installing them 772978

What a 5-STAR company. These Dexter tandem brake/bearing/seal kits and trailer breakaway kit are going to make my 1969 Airstream so much safer. I must say the original brakes ( I think) were still working ok but it was time to change them out. They beat my local price (local did not have set of 4 only 1) . I can't say enough about how pleased I am. 707610

  • How to Measure to Confirm Compatibility of Replacement Trailer Brakes
    Dexter Electric Drum Brake set # 23-105-106 is a left/right pair of 12 x 2-inch brakes that mount with 5 bolts. These brakes are intended for axles with a 6K weight rating. You'd need one kit per axle. These brakes can use mounting kit # BRKH12; use one kit for each set of brakes. To ensure compatibility you'll want to measure your hubs to confirm their size (see photo please) and check the mounting bolt pattern on your brakes flanges to make sure it too matches.

  • Troubleshooting Electric Trailer Brake Assembly Magnets
    We have an article to assist with checking your brake magnets like you are stating. The resistance will go down because the brake magnets are connected in parallel. Since the voltage doesn't change, the amperage draw needs to increase to power the magnets. This is Ohms law in action based on my research. You obviously already have a multimeter like # BTMT15 so if you determine based on the article that you need to replace magnets, I recommend # BP01-180 for 12 inch Dexter assemblies...

Please note that brake assemblies should only be chosen in part by the weight capacity of your axle. They also need to fit with your correct hub size, mounting flange bolt pattern and wheel size.

  • Can Dexter 6,000 Lb Electric Brake Kit Be Used On A 5,200 Lb Axle
    Yes, the brake assemblies part # 23-105-106 can be used on a 5.2k axle as long as the mounting flange bolt pattern is 5-bolts, the wheel size is 14-1/2", 15" or 16" and your existing hubs are 12" hubs. You will also need mounting bolts and hardware for 12" brake assemblies part # BRKH12. The only issue you may run into using brakes rated higher than the axle capacity is they could be too aggressive. However this can be overcome by adjusting the brakes themselves and/or turning down...

  • Troubleshooting Weak Electric Trailer Brakes
    For your electric brake assemblies, the first thing to note is that your ground on your brake magnets should be directly to the trailer frame. Each assembly should have the power from the wiring connection direct as well as the other wire of the magnet attached to the frame bare metal to metal with no corrosion or debris. The voltage you are getting on your 5 o'clock trailer pin looks good. When you hit the manual override, you should get even more of a boost. The emergency brake...

  • What Brake Assemblies Will fit 14.6 Inch Wheels?
    There are a number of brake assemblies which are going to fit wheels that are between 14-1/2 inches and 16 inches. In order to choose the right assembly, you will need to know your axle's weight capacity and the bolt pattern of the mounting flanges. For example, the Dexter Electric Trailer Brake Kit # 23-105-106 are 12" x 2" assemblies that fit 6,000 lbs axles and mounting flanges with a 5-bolt pattern.

  • Brake Assembly Dust Caps and Nut Recommendation for Brake Assemblies 23-105-106
    Sounds like you are looking for the dust cover plugs part # BP10-220 for the brake assemblies # 23-105-106. The bolts these are designed to fit to are actually studs that are attached to the mounting flange of your current spindle like the part # 4-44-1. For nuts and washers that fit that you'd want the part # 38LW and # 38N.

  • Is There Specific Spacing Needed for New Brakes and the Hub/Drum Assembly
    You want to adjust your new brake assembly, like part # 23-105-106, so that when you spin your tire/wheel you feel a little bit of drag. If you don't have any drag then your trailer braking will be weak but if you have a lot of drag then your trailer brakes will lock up with minimal power to them from the brake controller. If you are talking about the distance between the brake magnet and the drum then there isn't a specific spacing for this either as the magnet won't do anything until...

  • Troubleshooting Front Brakes Locking Up On A Tandem Axle Trailer
    Having already done adjustments and replaced multiple parts, you've really ruled out potential mechanical causes here. A next step would be to look at the electrical side of things. Specifically I would look at connection points in the wiring on the trailer to make sure all of the connections are correct and redo them. A short in the wiring to the back axle brakes could be the cause. During your thorough inspection of the wiring, look for any pinched, frayed, or damaged wires would...

  • Would Dexter 5,200 lb Trailer Axle have Manual Or Self Adjusting Brake Assemblies
    Dexter makes 5,200 lb trailer brake assemblies that are self adjusting like part # 23-458-459 as well as ones that are manual adjust like part # 23-105-106 so it could go either way. I attached a picture that points out what to look for on your assemblies once you pull off the hub to tell if they are self adjust or manual adjust. The steel cable you see is part of the linkage mechanism which makes the assemblies adjust automatically.

  • Recommended Brake Assemblies For 1978 Silver Streak Trailer with Hadco Axles
    For your trailer, you can reuse the bearings and hubs as long as they are in good working condition. For your brake assemblies I recommend the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA or the Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6,000 lbs # 23-105-106. Based on your Bearing sizes either of these assemblies will fit perfectly.

  • Is the Capacity of the Timbren Axle-Less Trailer Suspension System Per Side or Total
    For a Timbren Axle-Less Trailer Suspension System with a 7,000 lb capacity you will want to use part # TASR7KS02 which has the same 4" drop as the Timbren Axle-Less Trailer Suspension System part # ASR3500S04 that you referenced. The part # ASR3500S04 has a total weight capacity of 3,500 lbs, not per side. If you need the braking assemblies and hub/drum for the 7,000 lb system then you can use part # 42866UC3-EZ for the hub/drum and part # 23-105-106 for the braking assemblies. I have...

  • Replacement Brake Assembly Recommendation for 2004 Fleetwood Prowler Regal 32'
    Best option is to match the part number you found on your trailer. Realistically the 6k and 7k brake assemblies are mostly interchangeable as they both are 12 inch diameter by 2 inch width so either would technically fit, but going with the correct rating gives you a setup that's easiest to fine tune braking power. If you go with an assembly rated too high the magnet is more sensitive and you'll find that the brakes are harder to get the exact amount of braking power. It'll either feel...

    Part # 23-106 is a 12 inch manual adjusting brake that fits your drums. Even though it's listed for 6,000 pound axles it's still what you need on your 5,200 pound axles. It's the right hand side, like you mentioned and part # 23-105 is the left, or you can get the kit of them together with part # 23-105-106. Since you need three (whch I admit is a little strange since you should replae them in pairs) you could get the kit for tow of them and then an extra left hand assembly. Everything...
