See what our Experts say about this Dexter Accessories and Parts

• 12-1/4 x 3-3/8 Inch Electric Trailer Brakes for 9K and 10K Trailer Axles
  There are 2 different sets of 12-1/4 x 3-3/8 inch brake assemblies and the difference between them is the mounting patterns they have. Electric brakes # 23-450 and # 23-451 will bolt to either a 5-hole or 7-hole mounting flange and they are for 9K to 10K axles which is what the hub # 9-44-1 is for. Electric brakes # 23-434 and # 23-435 will bolt to a 4-hole flange and they are for 8K axles.

• 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...

• 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.

• Availability of Brake Installation Kit with Spindles
  Changing spindles on a trailer axle requires specialized jigs and is best left to a qualified experienced welder. Any deviations from perfect concentricity of the spindle and brake flange will result in bad performance and/or damage to the components. If you have the equipment and skills to do this that's great, but if not I urge you not take that on yourself. We do not offer kits with just spindles, brake assemblies and hubs, but we do sell axles with hubs, brakes, bearings, seals etc....

• 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.

• How to Determine The Axle Weight Capacity On A 20 Foot Stock Trailer
  The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity. You can also tell the weight capacity of the axle by measuring the diameter of the axle. A 3,500-lb. axle will have a diameter of 2-3/8 inches and a 6,000-lb. to 7,200-lb. axle will have a diameter of 3 inches. I am sending a link to an FAQ page on trailer...

• 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.

• 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...

• 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...

• Can Brakes Be Added to a Farm Wagon Used on Steep Terrain
  It is possible in some circumstances to add either electric or hydraulic (surge) brakes to a trailer that does not have them, so it is theoretically possible to do something similar on a farm vehicle. This process will be quite involved and will depend on availability of compatible parts that will work with your existing axles and spindles. It may be necessary (and even easier) to replace the entire axle/spindle assembly with a new one rated suitably for your load requirements that has...

• Electric Trailer Brake Assembly with 6-Bolt Mounting Pattern for 1960 Airstream Tradewind Trailer
  Some of the older Airstream trailers used unique proprietary components, including brakes. We do not carry any 6-bolt brake assemblies; but we have 4-, 5- and 7-bolt types that can be seen on the link provided, such as Dexter 12-1/4 x 3-3/8-inch brake # 23-450 and # 23-451, which can use a 5- or 7-bolt mount. You will need to first confirm the axle capacity and the diameter and width of your drums to check for a suitable brake. You may be able to find a compatible brake assembly but odds...

• Are there 12 x 3-3/8 Inch Electric Trailer Brakes
  Like you said we have 12-1/4 x 3-3/8 inch brakes but no 12 x 3-3/8 inch brakes. When measuring though measure the inside diameter of the drum and not the diameter of the brakes. I have included a picture showing what I mean. If you measure the drum and get 12-1/4 inches then you can use 12-1/4 x 3-3/8 inch brakes such as # 23-450. But if you are measuring the inner diameter of the drum and are getting 12 inches then we will not have brakes that match the specs you need.

• Replacement Electric Brakes Needed on a Kaufman Car Hauler with 10000 lb Axles
  Since your trailer was made in 2008, the trailer manufacturer should be able to tell you the exact brand and part numbers for replacement brakes. It appears there were two Kaufman trailer companies, one in Texas and one in North Carolina. The company in Texas closed, so it would be difficult to get specific information from them. I spoke with Kaufman trailers in North Carolina, however, they said they do not have any trailers with a TL designation. There should be an identification plate...

• Can Electric Brakes Be Used On Boat Trailer
  In the past it was never recommended to use electric brakes on a boat trailer because electricity and water do not work well together, but more and more people and boat trailer companies are switching. We still recommend disconnecting the trailer wiring from the tow vehicle before backing the boat trailer into water. You will need to remove your brake lines and then install wiring for the brakes. You will want to make sure you seal all electrical connections to keep moisture out. I...
