Video Transcript for Dexter 12 Inch Electric Trailer Brake Installation

Today on our trailer, we're going to be installing the Dexter 12" Electric Brake Assembly for the left hand or drivers side, part number 23-180. The dimensions for our brake assembly are designed to fit a hub drum assembly 12" in diameter with 2" wide or thick. These are designed up a 7,000 pound axle rating and have a 5-bolt mounting flange for the wheel. For this application, the reason we're replacing the backing plate assembly and brakes is because the hardware has come free from the brake shoe, allowing it roll around inside, damaging the grease seal, and contaminating the shoe linings. To remove the backing plate and brake assemblies, take the 5 hold down nuts off of the studs that go through the axle. Now we'll pull the backing plate off the studs. Note before we can go too far we'll need to disconnect the brake wiring. To do that, I'm going to take a pair of side cutters and cut it right here. Now we'll prepare our wiring for the new backing plate assembly.

I'll strip back the wires and add the butt connector. To make this connection point, we're going to use the Deca Heat Shrink Butt Connector for 22- to 18-gauge wiring, part number DW05743-5. We'll need to heat up the shrinkage portion of the butt connector. Using our heat gun, we'll do that now. Note if you don't have a heat gun, you could also use a lighter or a butane torch. Keep in mind to keep your heat source moving so that you don't actually melt the wire. Once we have the butt connector sealed up, we'll put the wiring back inside the wire loom.

Then I'm going to use some black electrical tape to tape up the end of the wire loom and any of the butt connector that's exposed. The remaining portion of our wiring can get secured here inside the built-in wire holder. Now we're ready to put our backing plate into position over the studs and then secure it with the nuts that we removed earlier. With everything reinstalled and tightened down, we can reinstall the hub drum assembly, and we're ready to hit the road. That will complete our install of the Dexter left hand or drivers side backing plate brake shoe assembly, part number 23-180, for our trailer install. .

These things are major time-savers! Bolt the whole assembly on, wire it up, and go! Can't beat the price either - would cost quite a bit more buying the parts individually. Made a huge difference in stopping power on my 18' Dively car hauler, 9990 GVWR. The brakes were 6 years old at the time, and had tens of thousands of miles on them - abusive miles too, with shoes seizing and dragging, electrical failures causing some to work 3x as hard as others, stop and go MA traffic, etc. While I was at it, I also grabbed 30' of Deka jacketed 2-wire 10 gauge brake wiring, and redid the whole system from the plug back. I also removed the drums, had them turned at a local garage, and installed brand new bearings, races, & seals. The improvement in stopping power was nothing short of amazing. I went from having my Tekonsha P3 on boost level 3 at 11 volts +, trailer UNLOADED, to running boost level 1 at 6 volts with 4,000 lbs. on the 2k lb. trailer! BIG difference in stopping power! 313993


Comments

So far so good! No problems with hanging brakes from being parked a majority of the time, on dirt, through wet and humid to freezing cold Massachusetts weather. Theyve also run through hundreds of miles of corrosive road salt. Had to make a few adjustments right out of the gate and am probably due for another after 2k or so miles, but thats normal break-in procedure. Well worth the price!

Do you have a question about this Accessories and Part?


  • Replacement Electric Brake Assemblies for Dual Axle Trailer with Different Capacity Brakes Installed
  • I really am not sure why different rated brake assemblies would have been installed on your dual axle trailer, as this is definitely not recommended. The 023-105-00 part number you found for the left side assemblies refers to the Dexter 6,000 Pound # 23-105, while the 023-181-00 part number refers to the 7,000 pound # 23-181. When replacing the brakes, I do recommend replacing them with assemblies of matching capacity. I recommend verifying the axle capacity on your trailer so you...

  • Will Dexter Brake Assemblies Fit on a Lippert Axle
  • You will have no problem using a Dexter brake assembly on a Lippert 7K axle. We have installed several Dexter brake assemblies on Lippert axles at our shop. Lippert and Dexter use the same standard mounting pattern and brake sizes. If you want standard brake assemblies, you could go with the Right Hand brake # 23-181 and the Left Hand brake # 23-180. I recommend stepping up to the Dexter Nev-R-Adjust brakes, # 23-465 and # 23-464. The cost difference is very minimal compared to the standard...

  • What Is The Difference Between the 6K and 7K Dexter Axle Electric Brake Assemblies
  • You are correct, the difference between the Electric Brake Assembly for 6K Axles, part # 23-458 / 23-459 and the Electric Brake Assembly for 7K axles, part # 23-180 / # 23-181, is that the 7K brake assembly has a stronger magnet, and also has a different compound on the brake shoes than the 6K electric brake assemblies for more stopping power. Both the 6k and 7K brake assemblies, fit the same axle. Yes, the 7K backing plates on part # 23-180 / 23-181, will fit on 6K pound axles.

  • Comparing the etrailer Electric Brake Kit and the Dexter Electric Brake Assemblies
  • In all honesty I would go with the etrailer Electric Brake Kit # AKEBRK-7-SA for a few important reasons. They are self-Adjusting, and the brake pads themselves are fully bonded so that they last longer and offer more braking torque, plus they have less chance of cracking and crumbling due to the tapered edge circular grinding. Even though the Dexter Brake Assemblies, parts # 23-180 and # 23-181, are still durable, the etrailer kit definitely has more to offer in this situation. If...

  • Can Dexter Nev-R-Adjust Brake Assemblies Replace Standard Brake Assemblies
  • The Dexter Nev-R-Adjust Electric Brake Assembly # 23-464 and # 23-465 will work great as replacements for the exiting Dexter brake assemblies # 23-180 and # 23-181 on your trailer. The # 23-464 and # 23-465 are designed to fit 7,000 pound axles and do not require manual adjustment. I have attached an installation video as well as an initial setup review video for you to check out.

  • Recommended Brake Assemblies For Gooseneck Trailer With Dual 7K Axles
  • With 7K axles on your trailer I recommend using brakes that are designed for your rig. Using 6K brakes on the trailer may not be sufficient. There are two differences between the 6k and the 7k brakes. The brake magnet regardless of the size magnet has more windings on the 7k which makes the magnet stronger. Also, the linings are constructed of different material between the 6k and 7k. The 7k material is more aggressive. Since price is a factor for you I recommend going with less-expensive...

The Dexter Electric Trailer Brake Assembly # 23-180 (Left Hand) and # 23-181 (Right Hand) are made in the USA; the accompanying photo is from one of these assemblies with the "Made in U.S.A." sticker on it. These electric brake assemblies are 12" diameter x 2" wide, fit 7,000 lb axles and have a 5-bolt mounting flange pattern.

  • USA-Made Dexter 12 x 2-Inch Electric Drum Brakes for 2003 Mobile Suites Trailer with Tandem 7K Axles
  • For Made in America 12 x 2-inch electric drum brakes for your 2003 Mobile Suites trailer with tandem 7K axles I recommend the Dexter kit # 23-464-465 for each axle if you want self-adjusting brakes. If you prefer standard manual-adjust brakes instead then use two of kit # 23-180-181. Either way you will want to order two kits to be able to fit new brakes on both axles. For mounting hardware you can use parts # 38LW, # 7-5 and # 38N (five of each per brake) and for a brake adjustment...

  • 5200 lb Axle Brake Assembly Torque Specs
  • According to Dexter Axle, the attachment bolts for a 5-bolt brake assembly should be torqued to 30-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close to that range.

  • Trailer Axle With Electric Brakes Options
  • The electric brakes we offer for a 7,000 lb axle are electric drum brakes like part # 23-181 for the right hand, and part # 23-180 for the left hand. The highest rated electric disc brakes we offer are electric-over-hydraulic and for 3,500 lb axles. This is the Titan Disc Brake Assembly, part # T10HREKITBB. The largest axle we offer is a 3,500 lb axle like the Dexter Trailer Axle w/ Electric Brakes, part # 35545E-ST-EZ-89. This axle measures 89 inches hub face to hub face and includes...

  • Replacement Electric Trailer Brakes for Dexter 7,000 Pound Trailer Axle
  • For trailer brake assembly # 23-428 to fit the drum will need to have an inner diameter of 12-1/4 inches and a width where the pads touch of 2-1/2 inches. I have included a picture showing these locations in a drum. This brake also mounts on a 4 bolt brake mounting flange. The 12-1/4 by 2-1/2 is not a common size though. The most common size brakes for a Dexter 7,000 pound axle is going to be 12 x 2 inch that mounts on a 5 bolt flange such as # 23-180 and # 23-181.

  • Hub/Drums and Replacement Assemblies for Dexter Axle with Assemblies 023-181 and 023-180
  • We have exactly what you would need. For the right hand side you would want part # 23-181, for the left hand side part # 23-180. Then for hub drums that fit that axle you'd want the part # 42866UC3-EZ.

  • What is the Difference Between the 7K and 6K Electric Brake Assemblies from Dexter Axle
  • There are two differences between the 6K and 7K brake assemblies. For the 7K, they use a semi-metallic compound on the brake shoes instead of the composite compound, and the magnets are stronger. This gives the brake assemblies more stopping power. They fit the same axles and spindle mounts, the only difference is how much weight the assemblies can safely stop. Choose the brake assemblies that have the weight requirement you need. 6K Left: 23-105 6K Right: 23-106 7K Left: 23-180 7K...

  • Replacement Electric Brake Assemblies for Camper with AL-KO T52 Axles
  • The Dexter Electric Trailer Brake Assemblys - Left Hand # 23-180 referenced in your question is rated for 7,000 pound axles. For the AL-KO T52 5,200 pound axles on your trailer, I instead recommend the etrailer.com Electric Trailer Brake Kit # AKEBRK-7-SA. These assemblies are designed for your 5,200 pound axles, measure 12 inches x 2 inches, and will indeed work with your AL-KO drums. You will just want to make sure the 5 bolt mounting pattern on these units match the pattern on your axle's...

  • Which Brake Assemblies fit a 5-Bolt Brake Assembly Backing Plate on a 6K Axle
  • I called my contact at Dexter and spoke with him at length about this. Mobile home axles are traditionally weld-on brake assembles that cannot be replaced. If they are actually bolt-on both the 6K and 7K weight capacities will work. Part # 23-105 and part # 23-106 are left and right side 6K capacity brake assemblies. Part # 23-180 and part # 23-181 are left and right side 7K capacity brake assemblies. They have the same mounting pattern and size. The 5-bolt brake assembly pattern is...

  • Availability of Rust-Proof Electric Trailer Brake Assemblies for Use in Sea Water
  • Generally electric trailer brakes are not ideal for use in or near water. Boat trailers generally use either drum or disk hydraulic braking systems to avoid mixing water and electricity, which generally do not like each other. The best brakes for salt water environments are stainless steel disc brakes, such as # K2R35S from Kodiak. It would not be a good idea to mix brake components from different manufacturers since these parts would not have been tested together.

  • How Much Torque Required When Tightening Attachment Nuts on 12 x 2, 7k Replacement Brake Assemblies
  • I spoke with my contact at Dexter and she informed me that you will need to tighten the attachment nuts to 30-35 ft-lb when installing 12 inch Electric Brake Assembly, part # 23-180, on your Dexter 7000 lb axles. I have attached a link below to a video of a similar brake hub being installed on a trailer that you might want to check out.

  • Replacement Brake Assembly Recommendations When Shoes and Magnets Need Replacing
  • By the time you replace the shoes and magnets of a brake assembly you are better off just replacing the entire assemblies since you will end up spending the same amount of money and would be getting all new assemblies that won't require disassembly and reassembly. You would want the # 23-181 and # 23-180.

  • How to Pick Out Replacement Brake Assemblies for a Travel Trailer
  • The best way to pick out replacement brake assemblies is to go with ones rated for the weight of your trailer, has the correct mounting flange bolt pattern, and will fit the hubs that you currently have. If your axles are rated for 7k, have a 5 bolt mounting flange, and have hubs that are 12 inch by 2 inch the part # 23-180 and # 23-181 would be the correct brake assemblies. I attached a help article for you to check out as well.

  • Replacement Brakes Needed for a #12 Dexter Torsion Axle
  • Thank you for the picture! I gave my contact at Dexter Axle the serial number off of your tag and he said that the replacement brakes for your #12 torsion axle include part # 23-180 for the left hand side and part # 23-181 for the right hand side. If you would like to upgrade to the Nev-R-Adjust brake assemblies then you would need part # 23-464 for the left hand and part # 23-465 for the right hand. The advantage to the Nev-R-Adjust assemblies is that you don't have to manually adjust...

  • The biggest difference between the 6,000 lbs Dexter Trailer Brake Assembly part # 23-106 for right hand and part # 23-105 for left hand and the 7,000 lbs Dexter Trailer Brake Assembly part # 23-181 for right hand and part # 23-180 for left hand is the axle rating they are used for. If your Dexter axle is rated for 6,000 lbs you would use the 6,000 lb set and if your Dexter axle is rated for 7,000 lb you would use the 7,000 lb set. Also the 6,000 lb Dexter Brake assemblies fit wheel...

  • If the assemblies # 23-105-106-09 that you have are held on using 5 bolts instead of 4 the assembly part # 23-180 will fit as a replacement since it uses a 5 bolt mounting bracket and is 12 inches in diameter.

  • What is Needed To Choose Replacement Axle for Homemade Trailer
  • You will need to replace the axle. I have linked you to our axle page. To determine which axle is compatible with your trailer, you will need to know the weight of the trailer, the hub face to hub face dimension and the distance between the spring seat centers and bolt pattern of the wheels. I'll link you to an FAQ that shows how to measure for bolt pattern, as well as to a diagram showing the measurements I'll need.

  • Should 7k Trailer Brake Assemblies be Used on a 6k Trailer Axle
  • Dimensionally they'll fit and they will operate but you don't actually get a stronger braking action. Instead the brakes will be harder to setup and get the correct amount of braking action. The heavier duty assemblies have a magnet that's more sensitive which helps with heavier weights but when used on a lighter trailer they become harder to setup and not anymore powerful. Best option is go to with 6k brake assemblies like the part # 23-459 for the right hand side and part # 23-458...

  • Recommended Replacement Brake Assemblies for Bandit Tandem Axle Dump Trailer
  • You will want to match up your four new brake assemblies to the existing ones to ensure they will mount properly to your brake flanges, fit your hubs and provide the correct stopping power. Its easiest to do this by pulling one of your hubs and measuring the diameter and width of one of your current brakes. Ideally you will also be able to find on the axles a sticker or plate that indicates the axle capacity so that your new brakes will have a capacity equal to or greater than required...
