This was just what I needed to upgrade the brakes on my trailer and very easy instructions



by:

I bought a used toy boxa and quickly found out that the breaks were mowed down. I had trip planned to Yellowstone so, I needed these fast. They showed up on time and were the right part. I put them on drive from SoCal to Yellowstone which is 1500 miles. I re-adjust the break one morning in Yellowstone and haven’t looked back. Thank you Etrailer.com!!!! Here is a picture of my trailer in Idaho. We camped here one night before we got to Yellowstone.

Parts all fit properly and worked great. Good product.

The brakes have been in for a year and work great. Installation was really easy. They came well packaged and with everything needed.

The new brakes work well on my trailer. However, when I replace them next time I will spend the extra $$ to get the self adjusting version.



by:

I replaced the electric brakes on my dump trailer, and bought the Dexter 6000 lb set, fully assembled and ready to bolt on. They fit perfectly and are of the quality that I expected for American made products. I am very happy with my purchase.



by:

These parts were made by Dexter and were an exact replacement for my Dexter axles.



by:

First shipment of two 23-105, and two 23-106 arrived with grease contamination soaked into the lining on two assemblies and impact damage to the lining on a third. etrailer shipped three replacements promptly. Sticker on carton said "quality checked by Alex G. Perhaps Alex should find another line of work.
My major issue however is that after installing these I had to crank the power on my controller to maximum to achieve any helpful braking and can't even come close to wheel lockup which you need to adjust properly. I noticed that the new magnets were oval shaped unlike my old ones which were longer and flat on top and bottom (like the magnets pictured on the 7000lb assemblies). I assumed the style had simply changed since my magnets were made and I had no reason to look at 7000lb brakes as my axles are tagged 4400lb. All instructions on etrailer site state to select the brakes by the weight of your trailer which in my case is 9000lbs. Surely four 6000lb brake assemblies would be overkill..WRONG! My axles are 7000lb "de-rated" to 4400 but they obviously had 7000lb brakes. This caveat has caused me to install the wrong brake assemblies! If you are replacing your brakes and wish to duplicate your stopping power, do NOT listen the the "expert" answers on here. Compare the shape of the magnets. These small oval magnets are not as strong and braking will suffer. I still feel as though I should be able to achieve wheel lockup with these but not the case and since they have now been used, I can not return them.


Comments
Double check the adjuster down at the bottom of the brake assemblies. That adjuster should be used when the brakes are first installed. Use the adjuster to open the assemblies so that theyre putting a slight and even amount of drag on the wheel as you spin it by hand. If you have used the adjuster as outlined above and the brakes still will not engage properly, give us a call at 800-298-8924 and our Techs will help diagnose.

I checked here locally on the cost of trailer brake shoes and magnets and found the price of etrailers' complete brakes and magnets assembled on a new backplate was by far less expensive. After removing the drum, this meant near zero labor, just five nuts to remove and replace the backplate then splice the wires. And another BIG plus, free shipping on an over thirty pound shipment. Wow so easy...And now I have all new brakes, magnets and all the other parts too, just seems to good to be true. I will continue to tell everyone about this labor saving and great priced product. Thank you etrailer.com.

Now a year later and 3,500 miles without any problem or issues. Looking back I am very pleased with my purchase and the excellent service provided by eTrailer. Thanks so much. Stay safe...

I was replacing the brakes on a 72 Airstream Argosy and needed a magnet but found out I could get whole new assemblies for $2.00 more! That's a deal! Just make sure if your backing plates have attached studs that you pick up the necessary grade 5 or 8 bolts, nuts and lock washers too.

Worked just fine. Sold the trailer

First time I ordered from E-Trailer and having a hard time navigating this and finding the right parts, I called. James took my call and help me find the right parts. I will be buying from here again.

Everything went well with the installation. Working with etrailer made things happen. Thanks etrailer.

I am writing this very favorable review of my online shopping experience with etrailer. Recently I had to replace the brakes, hubs, wheels and tires on my travel trailer. Please keep in mind that I am a 65 year old man without a lot of experience with online shopping. Never-the-less, I decided to give it a try in hopes of saving some money. To my surprise, etrailer made the experience very easy and painless. Before I placed my order on line, I had a question about one of the items on my shopping list, so I placed a call to them. I spoke with a very lovely and patient Customer Service Representative by the name of Michelle S. She was very helpful in answering my questions and encouraged me to call her back directly when I was ready to place my order; and so I did. During the shipping process, she kept me informed through emails the status of my order and everything arrived on time and in great shape. I truly appreciate the personalized services I received doing business with etrailer. They truly removed all of the uncertainty and nervousness of shopping online.



by:

Less work than buying all the parts separately. Parts came in good physical condition. However, on 1 of the 4 assemblies, the adjuster and adjuster spring was loose in the packaging but was easily made whole.



by:

EXCELLENT...... START TO FINISH. Fantastic service, great prices, quality products. Here's a before and after picture. It only took 30 minutes and basic tools to make the replacement. So much better than trying to clean up the old rusty one. Thanks again, Bill Borland in Michigan

Should have read the description better figured I was buying knock off parts. Much to my surprise they were genuine Dexter parts. Fit and finish was perfect. Very straight forward easy install. Shipped fast, very satisfied. Thanks etrailer!

Could bot be happier with the service in getting the right brakes. Better service than my local trailer shops. Thank you!

Brake assemblies were exactly as described. Installation was very straightforward and fairly simple. Total install time was two hours for 4 brake assemblies.

Thanks to Etrailer staff for helping me identify the right product needed for my trailer and also the speedy delivery getting me back on the road again.

  • Comparing Trailer Brake Assembly # 23-105 and # 23-105-09
    Trailer brake assembly # 23-105-09 is specifically designed to fit AL-KO/Hayes axles which are not as common as other axles. Brake assembly # 23-105 fits Dexter axles and other more common axles. If you have an AL-KO/Hayes axle, then I would go with them.

  • What is the Difference Between Dexter Trailer Brake Assemblies # 23-105-09 and # 23-105
    The difference is the mounting pattern. The Dexter # 23-105-09, brake assembly that you have referenced will mount to either an AL-KO/Hayes 4 bolt or a standard 5 bolt mounting flange. The # 23-105 just fits the standard 5 bolt pattern. Otherwise the specs are the same: 12 inch by 2 inch 6,000 pound axles Manual adjust Left hand side

  • How Often Should Electric Trailer Brake Shoes be Changed
    You cannot really go by miles when determining when brakes should be replaced. You would know to replace them the same way you would know with a vehicle. If performance is suffering and adjusting the brakes does not help and there are no other issues causing the poor performance it is probably time to change the brake shoes. Different applications, loads, driving styles and other factors have an effect on how quickly brakes will need replaced. Adjust the brakes every 3,000 miles or when...

  • What is the Difference Between Dexter 6k and 7k Electric Drum Trailer Brake Assemblies
    Electric drum brake assemblies for 6k and 7k axles both use the same 5 bolt mounting pattern. The 7k brakes will have a stronger magnet and will provide more braking. If used on a 6k axle a 7k brake assembly can be too aggressive but it could be used. The literature for the trailer should indicate the axle capacity somewhere. There may also be a sticker or plate on the axle with the capacity. It might also be stamped into the metal of the axle. I have included links to the 12 x 2 inch...

  • Troubleshooting Electric Trailer Brake Assembly That is Running Hot
    I would recommend completely ruling out the bearings by closely examining them and the spindle for discoloration caused by overheating. If you have determined that it is the brakes that are hot, and not the hub itself, I would recommend readjusting the brake assembly. What you are experiencing could certainly happen if the brake assembly was out of adjustment. To adjust the brake assembly, jack up trailer and secure on adequate capacity jack stands. Check that the wheel and drum rotate...

  • How Long Should it Take to Remove and Install a 6,000 Pound Trailer Axle
    The axle should be held on to the suspension with u-bolts so unbolting those should not take long and the axle should come right off. This is if the leaf spring stack is on top of the axle and I imagine, barring any unforeseen problems, that it would take no more than a half hour including putting the new on on. This would be if you had an assistant. If the leaf spring stack is below the axle then it will take a little longer because you will need to also remove the leaf spring stack so...

  • Finding Reason For Brakes to be Seized Up When Removing Trailer From Storage
    If no power is being sent to the trailer brakes, either by the brake controller or the break away system, the brakes should not be applied. The fact that the trailer isn't plugged into a tow vehicle and the break away battery has been removed completely rules out any electrical reason for the brakes to be locked. This leaves mechanical causes. You'll need to pull the wheels and hubs anyway, as they really should be repacked yearly. At this time you can inspect the brake assemblies to make...

  • Troubleshooting Low Brake Output Voltage
    First thing I would check is the blue wire that is at the rear of your vehicle for voltage when you apply the brakes and when you slide the manual override of this controller. You could also try sliding the manual override a few times and adjusting the gain knob up and down to help clear the contact points. If all this checks out it sounds like the problem is in the trailer somewhere. I would first check all the grounds of the trailer and make sure they are making solid corrosion-free...

  • Troubleshooting Brakes Locking Up While Using Trailer Mounted Brake Controller
    There could be one of a couple of things causing the brakes to lock up on your trailer. If the brakes are not adjusted properly. I have attached a video that shows how electric trailer brakes are adjusted you can check out. You said it is a very basic controller. If the gain is set too high, it can cause the same problem with the brakes applying too aggressively. You can lower the gain setting and see how that works for your trailer. You may have something in the controller or in the...

  • After Tire Blow Out on Trailer, Trailer Brakes Lock Up Unless Trailer Battery is Disconnected
    It is possible that the blow out you had somehow caused wiring damage that is not easily visible and that damage is causing a short. Or when the tire blew out it could be that it disengaged the pin on the switch of a breakaway system if you are using one. To reset a breakway just reinsert the pin in the switch. You will want to inspect the wiring starting at the trailer connector and working your way back. Make sure all grounds are attached to clean and corrosion free bare metal surfaces....

  • Trailer Disconnect Light Comes On, Chimes, on 2005 Ford F-250 without a Trailer Connected
    It sounds like there is a short. It is probably happening due to corrosion or dirt in the trailer connector on your 2005 Ford F-250. Make sure the connector is clean and free of corrosion on the pins and inside the connector where the wires attach.

  • How to Adjust Electric Drum Trailer Brakes
    If your horse trailer has electric drum brakes like # 23-105 then adjusting them is fairly simple. I have included a link to a video to the right. If you fast forward to about the 4 minute mark you can see how our installer adjusts the brakes. Basically you will adjust them out until you hear a slight but constant drag of the pads on the drum. There are specialty brake adjustment tools you can buy locally but the right sized flathead screwdriver should be all you need. There is a star...

  • Which Way to Turn Brake Adjuster to Tighten Trailer Brakes
    Turning the wheel so that the teeth on the wheel move upward will expand the brake shoes against the inside of the brake drums. Moving the teeth downward will contract the brake shoes. You can see the adjustment procedure by clicking on the video link I've provided. Simply fast forward to the 4:24 minute mark.

  • How to Determine if Trailer Has Manual-Adjust or Self-Adjusting Electric Brakes
    If you look at the photo I've provided of a self-adjusting brake assembly, you'll see the adjuster cable highlighted. If your trailer brake assemblies feature that adjuster cable, you've got self-adjusting brakes. Each time the trailer brakes are applied, the assemblies will make small adjustments as necessary to keep the brakes properly adjusted.

  • Trailer Brakes Only Work When Manual Switch on Brake Controller is Activated
    The controller is only putting out voltage when the manual switch is applied on the brake controller, but not when the vehicle brakes are applied, is that correct? The most likely problem is that the controller is not getting the input that the vehicle brakes are being applied. When the trailer is hitched up with the transmission in park, use a circuit tester like part # 3808 on the red wire exiting the rear of the controller. You should show voltage on the wire when the trucks brake pedal...

  • How to Adjust Electric Drum Trailer Brakes
    You are correct. On drum brakes that do not self-adjust, you would manually adjust the brakes using the star wheel on the assembly. Once you cannot turn the wheel, you turn the star wheel the other direction until the wheel can spin and you hear a slight constant drag on the brakes. If the brakes are not constantly dragging it could indicate wear on the shoes or drum. I have included a link to a video and at about the 4:39 mark our installed begins adjusting the brakes.

  • After Replacing Trailer Brakes, Worn Parts, and Brake Controller the Trailer Brakes are Weak
    One possibility is that you have a weak ground for the brake magnets. Check the grounds and make sure they are attached to clean and corrosion free bare metal surfaces. Do the same with the main trailer connector and vehicle side grounds. You will need to adjust the brakes since you have replaced the old ones. I have included a link to a video that should help. At about the 4:24 mark, our installer adjusts the brakes. They should be adjusted so that they drag lightly but constantly when...

  • Will This Brake Assembly Fit my Dexter 6,000 Pound Axles
    I pulled one of these off the shelves and checked the measurements against yours. The holes should match up and since this brake assembly is for 6,000 pound Dexter axles which is what you have, you should have no problem.

  • How to Test Electric Trailer Brake Magnets on Dual 6,000 Pound Dexter Axles
    I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further test your magnets, first make sure the trailer is not connected when performing this test. If the trailer is connected, you run the risk of shorting out a brake controller or various other electrical components. To test the brake magnets...

  • Trailer Brake Controller Shows No Connection to Trailer After Blown Tire
    I think I know what might have happened. When the tire let loose, it must have damaged the brake output circuit on your trailer. Each brake magnet has two leads, one that connects to the brake output circuit that leads to the trailer connector and ultimately to the brake controller. The other lead grounds to the trailer frame. If any of these wires has been severed, it'd cause the problem you describe. Start at the trailer connector, and trace the brake output circuit rearward to the brake...

  • Troubleshooting Trailer Brakes that Lock Up When Brakes Are Touched
    Sounds like your trailer wiring connector on your Ford F550 has the brake output and stop light circuit shorted together and when you apply the brakes the full 12 volts that is supposed to go to your trailer lights is going to your brake assemblies and locking them up. What you will want to do is clean the pins of the connector on your truck and then check the wiring of the connector looking for any cut or exposed wire and fix as necessary.

  • Troubleshooting Integrated Brake Controller that Only Works With Override Lever
    Sounds like the stoplight circuit signal isn't making it's way to the integrated brake controller of your truck so it's stopped working with the brake pedal. Since this is an integrated controller most likely the problem is a blown third brake light fuse. Replacing the fuse should fix the problem.

  • Electric Trailer Brakes Just Started to Lock Up when the Trailer is Connected to Tow Vehicle
    Since the brakes are locking up when the trailer is connected and release when the trailer is not connected then the brake magnets have to be wired to something. My guess is that the 5-Pole was not original on the trailer and the previous owner used some alternate wiring for everything. First we need to get the wiring right as far as which wires does which function. I have included a link to our help article on trailer wiring with diagrams that show the functions of vehicle and trailer...
