  • Replacement Brake Assemblies for Dexter 10k Axles on Gatormade Trailer
    We have what you need! Thanks for the photos. Even though the serial number is torn from the axle tag, we still identified the brakes you need with the Unique ID Number 124394998016 from your 10k Dexter axle tag. I confirmed with my tech at Dexter that you need the Dexter Electric Trailer Brake Assembly - Self-Adjusting - 12-1/4" # 23-450 (left side) and the # 23-451 (right side). These are direct replacements of brakes constructed for your 10k Dexter axles on your Gatormade trailer.

  • Replacement Trailer Brakes For Dexter 023-451-00 Electric Drum Brakes
    The Dexter Electric Trailer Brake Assembly # 23-451 being the part number 023-451-00 that you referenced is a right side brake assembly. The Dexter Electric Trailer Brake Assembly # 23-450 is the matching left side brake assembly. This is available as a kit # 23-450-451 since I always recommend changing brakes as a set. We have the etrailer Electric Trailer Brake Kit # AKEBRK-10 which will can also be used. These are the same 12-1/4" x 3-3/8" brakes pads as the Dexter brand and they are...

  • Replacement Brake Assemblies for 2019 Big Tex Gooseneck Trailer
    The Dexter Electric Brake Kit # 23-450-451 are the brakes you will need for your 2019 Big Tex 22GN with the 10,000lb Dexter axles. These are sold per axle so you will need 2 sets to replace all 4 of your brake assemblies. They are also sold individually as the Left # 23-450 and Right # 23-451.

  • What Size Brake Assembly Fits Dexter Trailer Hub and Drum Assembly for 9K to 10K Axles
    The Dexter Trailer Hub and Drum Assembly for 9K to 10K Axles - 8 on 6-1/2 - Oil Bath - Before July 2009 # K08-288-90 uses a 12" x 3-3/8" brake assembly like the # 23-451 and # 23-450. This means that the correct brake shoe width for this hub and drum assembly is 3-3/8" wide.

  • How to Determine If 12-1/4" Electric Brake Assembly is Left-Hand or Right-Hand
    The photo you sent in is of the Brake Dust Shield # BP15-085 which fits both the Left-Hand # 23-450 and Right-Hand # 23-451 Dexter Axle 12-1/4" electric brake assemblies. If these are installed on your 10K axle and you're needing to make sure the axle is mounted in the correct orientation then you should be able to determine which side is which depending on where the wiring is coming from and how the brake adjuster is oriented from the back side of the brake assembly. I'm attaching a photo...

  • Width of Brake Pads on 28 Foot Gooseneck Trailer With Dexter 10K Axles
    To determine which brake assembly you need, measure the width of your brake linings, as shown in the photo I edited for you. If your existing brake shoes measure 4 inches wide, the # 23-438 you mentioned would be an example of a good replacement for you if your existing brake assemblies use 7 mounting bolts (some use 4) and the diameter of the assembly is 12-1/4 inches in diameter when measured from the outside of one brake shoe directly across to the outside of the other shoe as shown...

  • Electric Brake Assemblies for a Trailer with Dexter 10,000 Pound Axles
    It is likely that Dexter brake assemblies # 23-450 and # 23-451 are correct for your 10K Dexter axles. These brakes mount with either a 5 or 7 bolt pattern. And they do have the correct measurements; 12-1/4 x 3-3/8. Take a look at the picture I have included showing the spacing between the mounting holes for this bolt pattern to determine if these brakes will fit.

  • Hub and Electric Brakes for Dexter SLR D90 9000-lb-Rated Axle
    Thank you for the photo of the brake assembly from your Dexter SLR D-90 9K axle. The correct hub you need for your Dexter D-90 axle is the part # 8-430-5UC3 which includes bearings, races, oil seal, oil cap, wheel bolts, and lug nuts. With this hub you can use Kodiak Synthetic Bearing Oil # XLPROLUBE. For brake assemblies you can use part # 23-451 for the right side brakes and part # 23-450 for the left side.

  • What Gauge Wire Should be Used When Installing Brake Assemblies on a Trailer

  • Replacement Bearings and Brake Assemblies For 1998 Dexter 9000lb Axle
    Thank you for the pictures and information of your axle! I called Dexter and your Dexter P12 SLR axle with Serial Number D-423-4057 has a 9000lb axle rating, and uses an 8 on 6-1/2 hub and drum assembly with 5/8" studs like you mentioned. For replacement bearings there is not a kit that has all of the bearings and races but you can purchase them all separately as follows: Inner Bearing # 387A Inner Race # 382A Outer Bearing # 25580 Outer Race # 25520 Oil Seal # 10-51 And Oil Cap Kit...

  • Replacement Electric Drum Trailer Brakes for a 10,000 Pound Wells Cargo Trailer
    The brakes on your Wells Cargo trailer could just be in need of adjustment. On drum brakes you will adjust the brakes so that there is a slight but constant drag of the pads on the drum when you turn the wheel. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. If the trailer has 2 axles then you likely have de-rated 6K axles (5200 pound axles). This size would be 12x2 inches. they mount to a 5-hole mounting...

  • Replacement Electric Brake Assemblies For a 2018 Big Tex 22GN Trailer With 10K Dexter Axles
    The Dexter Electric Brake Kit # 23-450-451 are the brakes you will need for your 2018 Big Tex 22GN with the 10,000lb Dexter axles. These are sold per axle so you will need 2 sets to replace all 4 of your brake assemblies. They are also sold individually as the Left # 23-450 and Right # 23-451 if you have a need to only replace one in the future. With self adjusting brakes like these it is more common for them to all wear evenly and need replaced at the same time.

  • Need Brake Assembly For Dexter Trailer Hub And Drum - 8,000 lbs Axles - 8 on 6-1/2, # 8-218-9,
    You mentioned a 12-1/2 inch drum, but Dexter only list a 12-1/4 inch X 3-3/8 inch drum. The parts that I am recommending are for the Dexter Hub and Drum, # 8-218-9, which is the 12-1/4 inch X 3-3/8 inch drum. I have the complete brake assemblies for the Dexter Trailer Hub and Drum - 8,000 lbs Axles - 8 on 6-1/2, # 8-218-9. The complete assemblies would contain the magnets, actuating arms, brake shoes and springs and cast backing plate. If you have the 4 bolt flange the brake assemblies...

  • Are Drums Interchangeable When Replacing Hydraulic Brakes With Electric Brakes
    I have attached a link to a helpful article that explains all of the components needed for adding electric drum brakes to a trailer. We always recommend replacing all of the components at one time so you are sure everything works well. If you check out your 9-44 drum you currently have and the inside surface shows no signs of wear or damage you can use them when changing from hydraulic to electric brakes. I spoke with my contact at Dexter and they told me that all you would have to replace...

  • Electric Brake Assembly Recommendation for a Dexter 10k Axle
    Yes, you can replace the hydraulic brake assemblies of your trailer with electric ones. It would just be a matter of removing the hubs, removing the old assemblies, installing the correct size/rated ones, and then wiring the assemblies back up to the trailer connector. I attached a help article that covers everything on adding brakes to a trailer as well as a picture of where to measure on your hubs so that you can pick out the correct size assemblies. Since you mentioned that you have...

  • Adding Brakes to a 3,500 lb Trailer Axle with 6 Lug Wheels
    We have hub/drums for a 3,500 lb axle with a 6 on 5-1/2 inch bolt pattern with the # AKHD-655-35-EZ-K which you'd then just need the brake assemblies # AKEBRK-35R-SA and # AKEBRK-35L-SA. Then to upgrade your 4-way to a 7-way all you'd need is the part # e99011 and you'd have that taken care of as well.

  • Troubleshooting Trailer Brake Assembly that Locks Up When Spun Forward
    Pull the hub off on the problem wheel. I bet your brake assembly has a mechanical problem and just needs to be replaced. For a replacement Dexter brake assembly for the right hand side of a 10k Dexter axle you would want the part # 23-451.

  • How to Adjust Drum Trailer Brakes Using a Brake Adjustment Tool
    Yes you can adjust the drum brakes on your trailer. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. Basically you will adjust the brakes out so that there is a slight but constant drag of the pads on the drum when the wheel is turned. I recommend using brake adjustment tool # W80630.

  • Electric Brake Assembly for Sundowner Horse Trailer
    We offer both complete electric brake assemblies and replacement parts for them. Often it is more cost-effective to replace the entire brake assembly than to purchase the various replacement parts to repair one but we can help with either option. Brake assemblies are selected based on axle capacity. For example, if your trailer uses a 10,000-lb-rated axle then appropriate electric brake assemblies for that weight capacity are available in two sizes: 12-1/4 x 3-3/8-inch and 12-1/4 x 4-inch....

  • Replacement Dexter Brake Assembly Recommendation for a 9k Dexter Axle
    So I was able to pull up some information on your Dexter Axle and based on the 008-232-05 number you listed it looks like you have a 9k rated axle. So for Dexter 9k brake assemblies you would want the part # 23-451 for the right side and part # 23-450 for the left side. These assemblies are 12-1/4 inch by 3-3/8 inch and are self adjusting. These also use a 6 lug bolt pattern to attach to the spindle of the trailer. Check out the review video I attached as well.

  • Installing Electric Brakes and Brake Controller for Use on 3500-lb 5th Wheel Trailer
    To start I suggest you review the linked article on how to add electric brakes to a trailer. This covers each of the components required and explains how to select appropriate parts for your particular application. Once your trailer is equipped with electric drum brakes and the necessary wiring to connect to your tow vehicle you will need to choose a brake controller. I suggest the popular and reliable Tekonsha Prodigy P2, part # 90885. You may be able to use a quick-connect harness to...

  • Replacement Bearings and Seal for Dexter 10k Trailer Hub
    The bearings you need are # 387A for the inner bearing, # 25580 for the outer bearing, and for the seal # 10-51 since we know you have a 10k Dexter axle. For brake assemblies you'd need the part # 23-450 for the left hand side and part # 23-451 for the right hand side. For a hub you'd need # 8-430-5UC3.

  • How to Select Correct Disc Brake Kit for Trailer
    The Dexter electric drum brake # 23-451 you referenced in your question does not require an electric-over-hydraulic (EOH) actuator since it will be powered directly by a brake controller in the tow vehicle such as the Prodigy P3 # 90195. The two Dexter EOH actuators we offer are parts # K71-651 for disc brakes and # K71-650 for drum brakes and these allow such a controller to work with hydraulic disc or hydraulic drum trailer brakes. Brakes for a trailer should be selected based on the...
