Dexter is the way to go. These were for a boat trailer I only use in fresh water.Tried less expensive knock offs, but they only lasted a year. I have been very happy with any Dexter Product. They are much better than others. 523935

  • Brake Assembly Recommendation for Loadmaster Boat Trailer
    From the info and picture you gave me I can tell you that the Dexter Hydraulic Trailer Brake Kit # 23-342-343 you referenced is exactly what you'll need. It fits the bolt pattern I see in the picture and has the 12 inch diameter you need as well. This is a pair for both sides of the trailer as well. To pick out a replacement grease seal you will need to measure the diameter of the spindle where the grease seal rides with a digital or dial caliper and then need to measure the hub bore...

  • Replacing Brake Assemblies of Loadmaster Boat Trailer Carrying 26 Foot Long Boat
    Based on what you described your trailer has 12 inch by 2 inch brake assemblies installed on it which is a very standard and common size. For a set of electric brakes that are self adjusting and will work really well as a replacement I'd recommend the etrailer 5.2k to 7k brake assembly set part # AKEBRK-7-SA. These will replace what you have easily and will give you new brakes that will work much better than your worn out set currently. I attached an install video for these for you...

  • Recommended Parts To Convert Trailer From Hydraulic Surge Brakes To Electric Over Hydraulic Brakes
    We do not have a specific kit but I can help you find all of the parts you need to convert your trailer from hydraulic surge brakes to electric over hydraulic brakes. With this conversion, you can choose from hydraulic drum or disc brakes. Generally, disc brakes provide stronger braking action than drum brakes which reduces required stopping distances and increases overall safety. Disc brakes also require less maintenance than drum brakes because they have fewer moving parts. Ultimately,...

  • Free-Backing Drum Brakes for M101A2 Military Dump Trailer
    To check the fit and compatibility for a set of replacement hydraulic drum brakes on your M101A military dump trailer you will want to match up a few things. Those things are drum dimensions, axle weight capacity, mounting bolt pattern and the compatible wheel sizes. The linked photo shows how to check your drum size. The Dexter free-backing 12 x 2-inch brake kit you mentioned # 23-342-343 is suitable for axles rated up to 7K, they use a 5-bolt mounting pattern and they fit wheel diameters...

  • Recommended Trailer Parking Brake for Parking Brakes
    We have the Dexter Electric Trailer Brake Kit w/ Parking Brakes - 10" - Left/Right Hand Assemblies - 3.5K # K23-086-087-00 and the Dexter Electric Trailer Brake Kit w/ Parking Brakes - 12" - Left and Right Hand Assemblies - 6K # 23-112-113. For 7 inch assemblies, use # K23-103-104-00. If you have hydraulic options the Dexter Hydraulic Brake Kit w/ Parking Brakes - Uni-Servo - 12" - Left/Right Hand - 6,000 lbs # T2351300-200 is the only option we have with the parking brake.

  • Can OEM Brake Controller on 2011 Ford F-350 be Used with Electric Over Hydraulic Actuator
    The OEM controller in your 2011 Ford F-350 is actually very similar to the Tekonsha Prodigy brake controllers so you wouldn't need to add an aftermarket controller unless you absolutely wanted to. There should be a setting for electric over hydraulic (EOH) brakes that you choose for this. If you do decide to use an aftermarket then I highly recommend the Prodigy P2 # 90885 because you will already be somewhat familiar with how to use it. All you need to complete the installation is the...

  • Replacement 12" Dexter Axle Hydraulic Drum Brake Kit with Parking Brake Lever
    The correct replacement for your Dexter Axle 023-340-00 and 023-341-00 brake assemblies is found with the Brake Kit # 23-342-343, but since you want the parking brake lever you'll need the kit # T2351300-200 instead. Most brake kits are fairly similar and the difference kind of boils down to personal experience, but in this case Dexter Axle is the only option we have available with the parking brake lever so there really isn't a comparison there.

  • Recommended Parts Compatible with Dexter P12 7,000 lb Axle
    We do not carry the replacement axle for your P12 7K Axle. We do however have the brake assemblies and bearing kit or hub/drum assemblies to assist based on what I can find online for a 7K Dexter axle. You will most likely want the Bearing Kit, 14125A/ 25580 Bearings, 10-36 Seal # BK3-200 to work with your axle and hub/drum assembly. To get the entire replacement assembly, you want the Dexter Trailer Hub and Drum Assembly - 5,200-lb to 7,000-lb E-Z Lube Axles - 12" - 8 on 6-1/2 # 42866UC3-EZ....

  • How Do I Back Up with a Surge Brake Actuating Coupler With No Reverse Lockout?
    The Titan Adjustable-Channel Brake Actuator - Painted - Disc - 2-5/16" Ball - Weld On - 14,000 lbs # T4750000 will allow you to either use the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 or you can use free-backing brake assemblies like # 23-342-343.

  • How Can I Identify an Axle Without a Sticker?
    Thank you for the pictures! It looks like you've got some sort of square drop axle on your trailer and if you can't find an identifying sticker, I can still help you figure out what you've got so that you can make the swap to electric brakes on your trailer. It looks like you've got 6 bolts on the wheels, which can help narrow down our search, but we'll need to know what size the brakes on the trailer are and if possible, what size (or number) the inner and outer bearings are on the...

  • Replacement Hydraulic Brake Assemblies With Parking Brake Integrated
    I was able to cross reference with the manufacturer and find the parts you need. I recommend the Dexter Hydraulic Trailer Brake Kit - Free Backing - 12" - Left and Right Hand Assemblies - 7K # 23-342-343 if you don't need the parking brake. If you want the parking brake, then I recommend the Dexter Free-Backing Hydraulic Trailer Brake Assembly w/ Parking Brake Lever - 12" - Right Hand # T2351200 and Left Hand # T2351300.

  • Replacement 12 Inch Brake Assemblies Compatible with Old Warner Trailer Hub/Drums
    You can absolutely use the Dexter 12 inch brake assemblies. If you have electric brakes then the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies # 23-458-459 with your current hubs. You may also want the new mounting hardware # BRKH12. For a more economic option that will work just as well, you may want to consider the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies # AKEBRK-7-SA. If you have hydraulic brakes,...

  • Hydraulic Trailer Brake Assemblies Compatible with the Dexter 8-174-5UC3 Hub Drum Assemblies
    The Dexter Trailer Hub and Drum Assembly - 6,000-lb and 7,000-lb Axles - 12" - 5 Spoke Utility # 8-174-5UC3 is compatible with either the Dexter Hydraulic Drum Brake Kit - Duo Servo - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-336-337 or the free backing Uno Servo # 23-342-343. The Duo Servo option will give you the best braking capacity with those hubs so that is my recommendation.
