Video Transcript for Dexter Axle Trailer Brakes - Electric Drum Brakes - 23-105-106 Review

Today we're going to take a look at the Dexter 12 inch electric trailer brake kit with the left and right hand brake assemblies for 6000 pound axles. Now electric brakes are easier to install. They offer more user control than hydraulic brakes. Basically they require only an electric brake controller, which we do sell separately on our website. There's no actuator or hydraulic lines necessary with electric brakes. Now these brakes are manual adjustment brakes so they do require period manual adjustment. You just go down here to the gear and adjust it in or out as needed.

The other nice thing is on this assembly, if you look on the backing plate right here, there's two holes on the bottom. Those are access holes to allow you to do the adjustment on your brakes. They come with these adjuster plugs, and what's nice about that is it covers those access holes, keeps any dirt and grime out of the brake assembly and off the brake shoes. Now this part number does include both the left hand driver side and right hand passenger side brake assemblies. You can also see the mounting hardware is included. Now basically on a 12 inch size brake assembly, which these are, they usually the brake mounting flange will have the bolts in them already so all you need is the lock, washer and nuts.

These include the integrated lock washer onto the nut. The dimensions on this, they're 12 inches by 2 inches. The 12 inches is the diameter and that's measured from this shoe to this shoe. So if we put a ruler on that, there's your 12 inches. The width is 2 inches, and that's the width of the brake pad on the shoe, so there's your 2 inches wide, and we had mentioned the brake mounting flange bolt pattern. You can see the five holes, so it does use the five bolt holes.

Now this does require the use of 12 inch brake drums. The wheel size that will work on these brakes assemblies is 14 and a half inches, 15 inches and 16 inches. The axles they fit on are 6000 pound axles. Now these are electric brakes so if you notice in the back, they do have two white wires coming out the back. One goes to the brake feed.

One goes to an ice clean ground and they're both white wires so either wire can be used for either function. The last thing I just wanted to show you is the difference between the, how you can tell the difference between the left hand driver side and right hand passenger side. Now on a new assembly of course the sticker will tell you that, but if the sticker wasn't on there, what you want to do is look at the length of the pad on the brake shoe. The length of this pad goes from here to here. On this it's just from here to here. This is the shorter pad. The shorter pad is always the primary shoe that faces the front of the trailer. That will tell you that this goes on the right hand passengers side. If you go to the other side, again the shoe goes, or the pad goes from here to here and the pad goes from here to here. This is longer. This one's shorter. This is the primary shoe so that will tell you this faces the front so that's your left hand driver side assembly. That should do it for the review on the Dexter 12 inch electric trailer brake kit with the left and right hand brake assemblies for 6000 pound axles.

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

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

Ask the Experts about this Dexter Axle Trailer Brakes

  • 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. If you can find a sticker...

  • 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...

  • Are Certain 12 Inch Brake Assemblies Interchangeable?
    The brake assemblies you referenced are the same except the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 are self-adjusting while the Dexter Electric Trailer Brake Kit # 23-105-106 require manual adjustment with a part such as # W80630. 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. Each of these assemblies work with 6,000...

  • 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. I've added a link to each of our available assemblies that fit wheels in your size...

  • 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.

  • 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...

  • 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...

  • 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...
