@Adrian Awesome! We're glad to hear that your Dexter # 23-105 brake assemblies are working well for you.

Excellent service!
Getting ready to place
another order!

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...



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.

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.



by:

Easy to instal and we’ve had no problems thus far.



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:

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

This part was a perfect replacement for the original which had failed after 18 years of service.

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.

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



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.

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:

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



by:

Wonderful service, exact replacement, delivered promptly!



by:

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!



by:

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:

Best value for genuine Dexter parts



by:

Superb service. All items were packaged and shipped shortly after order was confirmed. Parts were received on time and well packaged. Currently at shop to be installed.



by:

East to install and adjust. Once on the road broke in easily and they do a great job stopping my toy hauler.



by:

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:

Excellent service over the phone, arrived quicker then told when I ordered. Real easy to replace, 5 mounting nuts and the 2 wires for the brake hook-up. Can't beat the price, a lot better ordering the whole brake assembly then just the brake shoes. Hardest thing was dealing with the messy wheel bearings. As always, GREAT JOB ETRAILER.



by:

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



by:

It fit my 89 Airstream perfectly. Original unit broke a spring and totally self destructed. This and the brake drum with bearings fixed everything. About $50 cheaper than buying from my local brake shop who I have dealt with for 30 years.



by:

I had ordered some parts online to rebuild the suspension on one of our trailers. Customer service called me a short time later to inform me that they were out of stock on some items, they asked if it was possible to substitute some items. She was able to find the exact parts I needed in a different kit. The parts came within 3 days, very well packed, and they fit perfectly! This is the 3rd time I've ordered from etrailer and they have exceeded my expectations every time. EXCELLENT customer service and quality parts.

  • 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.

  • How to Pick Out Brake Assemblies for a Trailer with Idler Hubs
    Do you have idler hubs on your trailer currently? The way to pick out brakes for a trailer that has idler hub and a brake mounting flange is to first find the correct hub drum that fits the spindle and then go with the correct size/rated assemblies for those drums. To pick out the drums I'd need to know the diameters of the spindle where the bearings ride or the bearing numbers out of the hub as well as the bolt pattern of the hub where the wheel attaches. We can then pick out brake assemblies...

  • How Do Trailer Brake Assemblies Adjust
    Use a brake adjustment tool to turn the starwheel on the adjuster to expand the brake shoes until the wheel is very difficult to turn by hand. Then back off the starwheel in the other direction, about 10 clicks until the brakes drag slightly. Make sure all brake assemblies are adjusted in the same manner. Check out the video (see link). Beginning at the 4:23 mark, our installer shows how to adjust your trailer brakes.

  • 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...

  • Troubleshooting Trailer Hubs Where One is Hotter Than the Other
    If you turn the wheels by hand do you notice one wheel dragging more than the other? If so that would indicate additional friction which would create more heat. I imagine you'll find this to be the case. If the brake adjustments are the same and are good the other thing to check would be that the castle nut isn't too tight on the hotter wheel. Also make sure the grease seal is intact on the hotter hub and that the grease didn't leak out.

  • 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 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.

  • Troubleshooting Trailer Brakes Stopped Working with Brake Pedal on Truck
    If the brake controller on your Silverado 2500 stopped working with the brake pedal then there is likely either an issue with the connection between the controller's red (brake input) wire and the brake switch wire in the truck or you might just have a blown stoplight or CHMSL fuse. You can first try looking through your truck's owner's manual to find the location for those fuses to make sure they are in good condition, replacing as needed. If this doesn't resolve the issue then you...

  • 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 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....

  • Is it Normal to Hear Trailer Brakes Clicking
    The clicking you are hearing is normal. That's actually your brake controller sending a split second of amperage on the brake output circuit to see if a trailer is connected. This is basically just the test the controller performs to know if a trailer is connected. This would be unrelated to your bearing issue.

  • 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 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...

  • 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 Trailer Brakes That Will Not Disengage
    It sounds like you may be having some wiring issues; but first, start by checking your connectors to see if there is any corrosion that may be hampering their functionality and keeping your brakes engaged. To disengage your brakes, cut the power wire and that should disengage them. Then go over the wiring to try and look for any that are crimped, broken, or otherwise damaged. If you cut the wires that are feeding your brakes power and they still do not disengage, you will need to go to...

  • Recommended Torque Value For Installing Brake Assembly to 3500# Axle
    My contact at Dexter Axle tells me that when installing a brake assembly to the backing plate of a 3500 lb axle, the bolts should be tightened in a criss-cross pattern to between 45-70 foot lbs.

  • 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...

  • 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.

  • Do New Electric Drum Trailer Brakes Need to be Adjusted
    Yes, you will need to adjust the new trailer brakes. You will need to adjust out the shoes until there is a slight but constant drag of the pads on the drum when you turn the wheel. I linked a video to the right and if you fast forward to about the 4 minute 40 second mark you can see how the adjustments are done and how much drag you should have left on the hub.

  • Why Would Electric Trailer Brakes Lock Up When Hub is Spun Backwards
    There's something mechanically wrong with the brake assemblies or you have a drum that needs to be replaced or turned. Electric trailer brakes should not lock up when turned in reverse. Especially if there's no current involved on any of the wiring. That means it's a mechanical problem. Something in the linkage much be catching as the hub turns which is then pushing the shoes apart and activating them.

  • Which Trailer Brake Magnet is the Ground Wire and Which is the Power Wire
    Trailer brake magnets are not polarity specific which means that either wire can be the power or ground wire. So basically you get to pick which of the two wires you want to be the ground or the power wire.

  • One Trailer Hydraulic Brake Assembly Keeps Locking Up on Tandem Axle Trailer
    Resetting the breakaway feature on a hydraulic braking system can be a little complicated depending on the actuator used. On most it is not as simple as just putting the lever back into place. There are things on the inside that have to be reset/adjusted as well. That could be part of the problem. But before digging into that the easiest thing to check is if there is a mechanical issue with the brake assembly that is giving you trouble. It is possible, even likely, that crud, dirt, or...
