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. 637891

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. 520754

Ask the Experts about this Dexter Axle Accessories and Parts

  • Replacement Brake Assemblies and Hubs for 1960 Airstream Trailer
    It sounds like your assemblies are not the typical assemblies and will need to be replaced. For your brake assemblies, I recommend the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA along with mounting hardware # BRKH12. If you don't have the brake flange compatible, you can use the Brake Mounting Flange for 3" Round Axle # 4-44-1 which needs to be precisely welded in place. Then for your drum brake assemblies to match, I need some more information. I will need either...

  • How Does Trailer Electric Brake Assembly "Point" to the Front of Vehicle for Left or Right Hand
    I attached a picture that shows how the "pointing" of the arm looks. Basically if you look at the arm as the head of an arrow that will be the direction it points.

  • How To Tell If You Have Manual or Self-Adjusting Braking Assemblies
    The only true what to tell if a trailer has self-adjusting or manual adjusting braking assemblies will indeed be to remove the hub and look for the self-adjust cable (see photo). I am not aware of another method for this as the model number (if present) is generally placed on a sticker inside the assembly which also requires you to remove hub. The adjuster plug would be the same as well regardless. That said, although not as exact as the above if you were to craw under the trailer and read...

  • Can Dexter 23-105 and 23-106 Brake Assemblies be Replaced with Self-Adjusting Assemblies
    You could easily swap out your Dexter manual adjust assemblies part # 23-105 and # 23-106 for a set of self-adjusting assemblies. For that I would recommend the part # AKEBRK-7R-SA for the right hand side and part # AKEBRK-7L-SA for the left hand side. These will install in the exact same way as your current assemblies. There would be no modifications needed at all.

  • 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.

  • 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...

  • 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...

  • Need Tang Washer Axle Nut Retainer Clip for Dexter 6000-lb Axle with 6 Lug Wheels
    We offer part # 5-101 from TruRyde which is a tang-type washer intended for EZ-Lube spindles. This washer has a tab that fits between the notches on the castle nut to hold it in place. The inner diameter of this washer is 1-inch. The linked video will provide a demonstration of the installation. We also offer a D washer # 5-23 that is installed on the spindle before the tang washer.

  • 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.

  • 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...

  • Using Two Brake Controllers To Tow Trailer With Six Axles
    This is a tough one. we contacted our supplier and they said you will need to run 2 separate brake controllers like part # 90195. You will need to split the brake signal from the towing vehicle and attach it to the red wire on each of the brake controllers. Then run both power wires from the controllers to the positive battery post with circuit breakers. Both brake controllers would have to be set exactly the same so you maintain even braking. You will then need to run both Blue...

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • Converting Trailer from Surge Brakes to Electric Brakes
    First you will need to remove the old hydraulic equipment. Remove the surge coupler or actuator, remove all the lines, and finally remove the brake assemblies. If you have 10 inch diameter hub and drums, you may need to replace those as well. If you have 12 inch hub and drums, you can re-use them so long as they are in good shape. You will install your new electric brake assemblies, like part # 23-105 and part # 23-106. The magnets have 2 wire leads, one for ground, one for power. It...

  • One of Four Electric Trailer Brakes Locks Up When Brakes are Applied
    Since your brake controller appears to be working - 3 of the 4 trailer brake assemblies work correctly - the issue is likely to be on the trailer side. The issue with one of your four brake assemblies locking up could be due to it needing adjustment or it could indicate a problem with one or more of the components in the brake assembly. There could also be an outside chance that the spindle on that end of the axle is bent, which could lead to excessive pressure on the brake pads. First,...

  • Can 5 Lug Hub Replace 4 Lug Hub on Harbor Freight Haul Master
    You would need to change out the hub like you mentioned, but that's not normally a huge deal. You'd just have to first determine what hub you have now so that we can pick out the correct one that fits it. You will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where...

  • How to Find Which Trailer Brake Assembly Goes on the Left or Right Side of a Trailer
    The left side is the driver side, right side is passenger side. On a trailer brake assembly like # 23-105 the arm that the magnet is on points to the front of the trailer and the magnet always will be on the bottom. I have included a picture that shows what I mean. The matching right side assembly is # 23-106.

  • Which Direction Is Trailer Brake Adjuster Rotated to Contract Brake Pads
    To tighten the brake adjuster, you'd use an adjusting tool like # W80630 and spin the wheel upwards. To loosen or contract the brake shoes, you'd rotate it downwards, as shown in the video I've linked you to. You'll need to fast forward the video to the 4:50 mark.

  • 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...

  • Troubleshooting Factory Electric Brake Controller Not Working on a 2005 Ford F-350
    I agree that you most likely have an issue on the truck side. The voltage at the brake magnets when the vehicle is sitting still and the brake pedal is pressed will only read a small amount with the Ford integrated brake controller on your truck. If you are using the manual slide to activate the trailer brakes you should get somewhere between 12 and 13 volts with the controller set to the maximum setting. If this is the case there may be an issue with the brake controller. The 2005 and...

  • 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...

  • Weak Braking Performance with Electric Drum Brakes on 6000-lb Tandem Axle Sealcoating Rig
    On the Dexter Electric Brake Assembly you referenced, part # 23-105 rated for 6000-lb axles, the pad thickness varies slightly across the arc-shaped curve of the pad. I measured one with a precision digital caliper and found that pad thickness varies from 0.20-inches in the center of the pad to 0.18-inches at the ends. If your brake pads have 3/32nd-inches of pad thickness left (or 0.093-inches) then this clearly indicates wear that could, but does not necessarily, explain your weak braking...

  • 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...

  • Trailer Brake Assembly Recommendation for Dexter Assemblies Marked 023-106 for Both Sides of Axle
    Sounds like you need the brake assemblies part # 23-105 and # 23-106 to provide you with brake assemblies for both sides of your trailer. These are 6k Dexter brake assemblies that are 12 inches in diameter. For a replacement nut the part # 38N typically is what is used. For a lock washer part # 38LW.

  • 12 inch Brake Assemblies and 5 Bolt Mounting Flange Recommendation for an Old Warner Trailer
    This is quite the dilemma that took me a few readings to understand completely. There's no easy answer though since as you realized all of the 10 inch brake assemblies require a 4 bolt mounting flange (you have a 5 bolt flange), and none of the 12 hub/drums we offer have a 5 on 5 inch bolt pattern like what your trailer wheels need. I believe your best possible solution would be to remove the brake mounting flanges you have on your trailer and install new ones that will match up to the...

  • How to Determine What Hubs Are Needed for Escort Boat Trailer
    Yes, you can replace your hydraulic brakes with electric brakes. You will need to know your axle capacity and have the appropriate brake mounting flange. For example, with a 12" x 2" drum there is the Electric Trailer Brake Kit # AKEBRK-7-SA, which is for axles with a 5,200 lb - 7,000 lb capacity and will work with a 5-bolt mounting flange such as # 4-44-1. You will also need a brake controller, breakaway kit and wiring, some of which is vehicle-specific. Second, in order to find the...

  • 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...
