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

Excellent service!

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.

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 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 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 Original Dexter brand are better quality than the generic replacements.

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

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

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



by:

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



by:

the rep
s were will helpful and the
shipping was fast. ABD THEY WERE VERY polite ..will order again from etrailer



by:

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:

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 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:

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.

Wonderful service, exact replacement, delivered promptly!

Great price, quick shipping. Perfect bolt on replacement. etrailer is awesome.

Parts were perfect, still using them regularly. I need an axle but only see spindles online. Do you carry complete axles?

Etrailer Expert

Thanks for the follow up, we do have some axles, and some axless options. I have included a link of our current offerings for your reference.


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:

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.



by:

Didnt realize how bad the brakes were until they were replaced! Now, the trailer actually stops!!!

Perfect! The brakes work as they should. Perfect fit!!



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:

I was repacking bearings and noticed brake shoes questionable. I changed all four brake assemblies. It was a breeze and very cost effective. The only way to go!

  • 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.

  • 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.

  • 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.

  • 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...

  • Should All Trailer Brake Assemblies Have Same Adjustment Tension When Spun by Hand
    You'd want to get the drag as even as possible between all of the assemblies so that you get uniform braking activity. The 10 clicks back from lock up gets you pretty close but you'd want to fine-tune them as much as possible to be all the same. Based on what you did to get them all as tight as the tightest one you would be fine as-is.

  • 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 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 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...

  • 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...

  • How to Measure 5 Lug Trailer Wheel to Determine Bolt Pattern
    You most likely have a 5 on 4-1/2 inch bolt pattern but you would want to re-measure to be certain. The following dimensions from one stud center to the other will tell you which you have: 2-5/8" - the bolt pattern is 5 on 4-1/2 2-3/4" - the bolt pattern is 5 on 4-3/4 3" - the bolt pattern is 5 on 5 3-1/4" - the bolt pattern is 5 on 5-1/2 It also doesn't look like you have a standard trailer tire size on your trailer either. The closest we have is the 205/75-15 which I attached a link...

  • 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....

  • 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.

  • 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...

  • 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...

  • Electric Trailer Brakes Locking Up On One Side Of The Trailer
    If it is only happening on one side then it could be a short in the wire for that side, a mechanical issue with the moving parts with in the brake assembly and or a foreign object became lodged inside the drum. I would check all of these and also check the bearings to make sure they are not damaged. If all is clear then it is most likely a mechanical issue with the brake assembly itself. To make it easier on yourself I recommend replacing the brake assembly.

  • How to Determine Which Side of Trailer a Brake Assembly Should Install On
    The easiest way to tell if a trailer brake assembly is installed on the correct side of the trailer is to pull the hub off and look at the actuating arm. The arm should be in front of the spindles on the side closer to the front of it. See attached picture. The picture you sent in I believe is for the right hand side but without a part number listed on that stamping it's hard to determine for sure.

  • Troubleshooting Trailer Wiring Error Code that Shows Intermittent Connection
    Most likely your trailer connectors have a bit of corrosion in them which is causing an intermittent connection for your trailer wiring.

  • 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 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...
