Video Transcript for Dexter Axle Trailer Brakes 23-399 Review

Today, we're going to take a look at the Dexter 7-inch, right-hand passenger side uni-servo hydraulic trailer brake assembly for 2,500 pound axles. Now, this hydraulic drum brake assembly is a uni-servo design, which is used on trailers with surge-type trailer brake actuators. A uni-servo means it's a single plunger design. This design allows about 20% braking in reverse. The size on this assembly is 7-inches by 1 3/4-inches. This one is a passenger side trailer brake assembly.

The size, where they get that size from, is the 7-inches would be the diameter from this shoe to this shoe. If we put a ruler on it, there's your 7-inches. The 1 3/4-inch size is the width of the pad on the shoe, 1 3/4-inches. Again, this is the right-hand passenger side. The way you can tell that, now on all new assemblies it'll have a sticker that'll say right-hand side.

If the sticker wasn't there, the easiest way to tell is look at the size of the pad on the brake shoe. This pad goes from here to here. This one's from here all the way to here, so this is a longer pad, this is a shorter pad. Shorter pad is your primary shoe and that'll always face the front of the trailer, so that'll tell you that this goes on the passenger side. These brake shoes are aligned with an automotive grade friction material. It is fully bonded, it's not riveted inaudible 00:01:13 for a longer life, more braking torque.

It does require period manual adjustments, right down here is your adjustment gear. The backing plate has a nice e-coating 00:01:23 on it for excellent corrosion resistance. This does include the adjuster plug down here. When you go to adjust your brakes, you pop that plug out and put your adjustment tool in there to adjust it. Then you put this plug back in.

The plug is needed because it helps keep dirt from getting into your brake assembly. This does use 7-inch drums. Does include the mounting hardware, the four nuts right here that you install this with. This assembly is certified by USSA standards and the Canadian CSA standards. That should do it for the review on the Dexter 7-inch, right-hand passenger side uni-servo hydraulic trailer brake assembly for 2,500 pound axles.

Installed easily, quality was good. Doesn't come with the stud nuts, glad I could reuse the old ones. Also doesn't come with new adjustment hole plug. These are standard parts with auto brake assembly kits. I would buy this again. 219593

Perfect fit however it does not come with the adjustment plug. My old one was missing so now I have to try to find one locally. Other than that great communication from etrailer and fast shipping. Thank you. 237484

Do you have a question about this Trailer Brake?


  • Parts Needed to Change Hydraulic Trailer Brakes Over to Electric Brakes on a 1997 Jayco Tent Trailer
  • You will need two of the 7 inch electric brake assemblies, one right hand, # 23-48, and one left hand, # 23-47. You will also need an appropriate length of 10 gauge wire, item # 10-2-1, for running the wires to the trailer connector at the trailer coupler. Next, you will need a trailer connector to match the wiring on your vehicle, or the wiring you will need to install on your vehicle, to activate the electric brakes. I would recommend the Pollak trailer connector, item # PK12706, for...

  • Installing Hydraulic Trailer Brakes on a Kristi Utility Trailer
  • There are two ways to go. Drum brakes and Disc brakes. To determine which assemblies will fit on your spindles we will need to know the inner and outer bearing and seal part numbers. We will also need the Brake Mounting Flange bolt pattern on the spindles and the bolt pattern and size of the wheels that are on your trailer. For the hydraulic actuator we will need the size of the trailer tongue where the actuator will mount. If you will get back to me with your choices and the needed...

  • Can 7 Inch Hydraulic Trailer Brake Drums be Used with Electric Brakes
  • The Dexter hubs for hydraulic brakes # 23-399 and # 23-398 indicate that they are for use with hydraulic brakes only so you would not use them with electric brakes. The inside surface where a brake magnet would stick (called the armature surface) is not the correct design for electric brakes. In order to go to electric brakes you would also need to change the hubs. To keep the same bolt pattern you can use hub # 8-173-16UC3. And then you would need brake assembly # 23-48 for the right...

  • Adding Brakes to Acme Car Dolly
  • We don't offer parts specific for the Acme tow dolly, but we have the parts you'd need to add either electric or hydraulic drum brakes. I'm assuming your tow dolly doesn't currently have brakes, and that your current hubs use the # L44649 as the inner and outer wheel bearing. If that's the case, to add electric brakes, you'd need the following parts: # 8-257-5UC3-EZ hub drum for EZ lube spindle or # 8-257-5UC3 for standard spindles # 23-47 and # 23-48 electric brake assemblies # H20044...

  • 7 x 1-3/4 Hydraulic Brake Assembly Replacement
  • You can replace the Atwood hydraulic brake assembly with the Dexter hydraulic brake assembly as long as the mounting bolt pattern on the assembly matches. I went to the warehouse and measured the Right and left Dexter, 23-399 and 23-398, Hydraulic Brake Assemblies and they have a 2-7/8 inch on center four bolt pattern.

  • Looking for a Spring Kit For Atwood Brake Shoes Part # bp04-060
  • I spoke with our technical contact with Atwood and he informed me that the springs that fit the Atwood Hydraulic Brake Shoe # bp04-060 are no longer available. Dexter has a complete hydraulic assembly that will fit your 7 x 1-3/4 requirement. The Dexter 7 x 1-3/4 Hydraulic Brake Assembly # 23-398 is for the left hand and the Dexter right hand side is # 23-399.

  • Brake Line Kit Recommendation for Dexter Brake Assemblies 23-398 and 23-399
  • Trailer brakes use the same thread size whether they are disc or drum. The Kodiak Hydraulic Brake Line Kit # 20TA-BLKIT that you referenced would work well with the Dexter drums # 23-398 and # 23-399.

  • Hub and Drum and Bearing Kit to go with 7 x 1-3/4 Inch Hydraulic Brake Assembly 23-399
  • I believe that in the question you are referring to the 1.64 measurement is on the brake mounting flange, # 4-34. The center hole of the brake assembly, # 23-399, is larger than this and that is normal so it doesn't sound like you have anything to worry about for that. The matching left hand brake assembly is # 23-398. For a hub and drum assembly you can use # 8-276-5 which has a 4 on 4 bolt pattern and you would use bearing kit # BK1-150. For a 5 on 4-1/2 bolt pattern you can use hub...

  • Can Dexter Hydraulic Drum Brakes be Used in Place of Atwood 7 x 1-3/4 Inch Brakes
  • There should be no problem going with Dexter hydraulic drum brakes # 23-399 and # 23-398 in place of the Atwood brakes. You just have to make sure that you have the correct mounting pattern for the Dexter brakes. The Dexter brakes mount on a 4 bolt flange. The holes are 2-7/8 inches apart on center. The center hole is 1.64 inches in diameter. If this matches your flange then you can use the Dexter brakes.

  • Aluminum Car Trailer Restoration and Replacement Brake Recommendations

For your 1989 Trailex CT-7031 all aluminum trailer with the specifications that you provided there are three options for restoring or replacing the brakes for this trailer. The three options are similar to what you mentioned, and are: 1.Hydraulic Drum, which is the most cost effective. 2.Hydraulic Disc, which is more expensive, but provides better performance. 3.Electric drum, which is most cost effective...
