The product is good but the packaging was insufficient and it arrived damaged. I was able to source a replacement from elsewhere and just never had time to follow up...




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.

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

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:

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.

Well built not goodvto put everything in one box ups destroyed the box parts were all there . Yea

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.

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.

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

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...

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




by:

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

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:

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.




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:

Good price, great quality, easy install ation.


Comments
After a cross country trip, I have to say I am very pleased with the product performance. I would recommend etrailer and its products to everyone I know.

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

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

  • 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

  • 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.

  • Mounting Holes on 12 Inch by 2 Inch Break Assemblies 23-105 and 23-106
    The brake assembly mounting pattern is different than the wheel assemblies for trailers or cars. The difference being that the wheel has to rotate in balance to provide a smooth ride but the brake assembly is stationary with the drum and wheel spinning around it. Measuring between the bolt holes, the measurement is 2-1/8 inches on center for all bolt holes except the widest pair, on the bottom, which is 3 inches on center. The diameter of the holes in the backing plate for securing the...

  • 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 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...

  • 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.

  • Can Nev-R-Adjust Brake Assemblies Be Mixed with Manual Adjust Brake Assemblies on Trailer
    As long as all of your brake assemblies are adjusted properly it wouldn't matter if some of them were manual adjust and other were Nev-R-Adjusts. If the manual adjust brakes aren't kept in proper adjustment the Nev-R-Adjust assembly will end up wearing out quicker as more of the braking will be down with this assembly since the others wouldn't be as powerful. Ideally you would want to have the same on all wheels. I attached a page that has all of the brake assemblies we carry. You will...

  • Troubleshooting Trailer Brake Adjusters and Springs that Break on Right Side of Trailer
    I spoke with a couple of the other experts and installer here and the only thing we can come up with is that maybe you have left hand brake assemblies installed on the right side of your trailer and that is why you are experiencing the issues with the adjusters and springs. The actuating arm (the arm that holds the brake magnet), should be in front of your spindle. Another way to look at it is that if the arm was the end of an arrow it should point to the front of your trailer. Check out...

  • 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...

  • 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...

  • 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...

  • Bolt Torque for Installing 12 inch Brake Assemblies on 6k Axle
    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 # 23-105, on your Dexter 6000 lb axles.

  • 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...

  • Troubleshooting New Electric Trailer Brakes That Engage Only Weakly
    Brand new electric (and hydraulic) trailer brakes, even adjustable types, can take some time to settle in after installation. In general it is best to do several test runs at 40 mph before adjusting the brakes. You will want to hook up your truck and trailer, drive around and apply the manual override from your in-cab brake controller. Set the controller power and/or boost to maximum. You will want to start around 40 mph and use ONLY the manual override to slow down the truck and trailer....

  • How to Pick Out Trailer Hubs for a Boat Trailer with Surge Brakes and Unknown Hubs
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out.

  • Troubleshooting Weak Trailer Brakes Where One Magnet Does not Activate
    Since you ordered new brake assemblies I would think that once you install those and properly set the brake tightness you would be good to go. If the one magnet wasn't getting any voltage to it then that would explain why that assembly wouldn't activate. The voltage you tested for at the trailer connector would be normal if your controller was set for 5.25 volts as the max gain. For proper initial trailer brake assembly setup check out the video (see link). Beginning at the 4:23 mark,...

  • How to Determine Proper Brake Assemblies for Chaparral Lite 5th Wheel
    I don't have a reference source that would tell me what brake assemblies were used on your fifth wheel, so to determine the correct brake assemblies needed, we'll need to do a bit of detective work. The brake assemblies you need will depend on the diameter and depth of your brake drums, the number of bolts the existing brake assembly uses to mount to the brake mounting flange and the axle's capacity. To get the correct size (10 x 2-1/4 or 12 x 2 inch are the most common) you would measure...

  • Troubleshooting Trailer Brake Controller that Shows Trailer Disconnected Message
    The most common cause for a trailer brake controller to display the 'no trailer connected' error message is a damaged or corroded connector either on the vehicle or on the trailer. Corrosion can occur inside a connector too so you'll want to inspect both the external contacts and the back/inside of the connectors if possible for signs of any corrosion. Also check any wiring that plugs into the back of the vehicle socket. Even slight greenish or whitish discoloration can indicate a corrosion...

If you check out the FAQ article I attached you will see exactly how to add brakes to a trailer that didn't have any.

  • Matching Wiring from RV Traditional Wire Colors to RV STANDARD Wire Colors
    There can be two standard type of trailer wiring color codes seen. Sounds like your motorhome's 6-way uses the colors that are green for taillight, brown for right turn/stop, red for left turn/stop, white for ground and black for 12 volt power (not used). So you'd run your 4-way colors of green on the 4-way to brown on 6-way. Yellow of 4-way to red of 6-way. White to white. Brown of 4-way to green of 6-way.
