Video Transcript for Dexter Axle Trailer Brakes 23-342 Review

Today we're going to take a look at the Dexter 12" left-hand driver side free backing hydraulic drum break assembly, for 7,000 lbs axles. Our hydraulic drum brake assemblies are designed for use with surge type trailer brake actuators, this one happens to be a free backing design which let's you back up without engaging your trailer brakes, even if the actuator is activated. Basically, the hydraulic pressure is contained by the wheel cylinder and it has a fall-away shoe, it will diminish the shoe drag while backing up. You can usually tell by looking at them it's a free backing, the design of that fall-away shoe has a D-shape to it. This is a manual adjustment brake, so it does require periodic manual adjustment. Right down here is the adjustment gear that you just turn to adjust it, and you would access that usually through the rear backing plate.

They have an access hole right here down at the bottom. What's nice on this assembly, if you notice, they usually leave that hole open, here they've actually put a nice plug in there to cover that whole. Keeps any dirt and grime out of your brake assembly and off your brake shoes. This part will include the left-hand driver side brake assembly, and if you notice it also comes with the mounting nuts that have the lock washers attached to them. Basically, on 12" sized brake assemblies, the bolts are already attached to the brake mounting flange, so when you slide this onto those bolts all you have to do is take the nut with the integrated lock washer and put it in there and tighten it down. A few specs on this. The diameter is 12", the width is 2", and where they measure that, the diameter will be from this shoe all the way over to this shoe.

You can see, there's your 12" diameter, and the 2" wide would be the width of the pad on the brake shoe, there's your 2" wide. We had mentioned, you can see the five holes here, so it does use a brake mounting flange bolt pattern of five bolt holes. It does require the use of 12" brake drums. The wheel size that will fit on this is 14 and a half inches, 15 inches and 16 inches, and again it's designed for axles rated up to 7,000 lbs. The last thing I just want to show you is how to tell that this is the left-hand driver side design. On a new assembly, of course, it will have a sticker that will show you that, but if the sticker wasn't there, easiest way to tell is just look at the length of the pad on the brake shoes.

This pad goes from here to here, over here it goes from here to here, so this is a lot shorter shoe or pad. The shorter pad would be the primary shoe, that will face the front of the trailer, so that will tell you that this goes on the left-hand driver's side. That should do it for the review on the Dexter 12" left-hand driver side free braking hydraulic drum break assembly, for 7,000 lbs axles.

  • 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 where...

  • Replacement 12x2 Free Backing Surge Brakes with Part 023-342-00
    Thank you for the photo! Since your current drum brake assembly is part 023-342-00 from Dexter Axle the replacement brake kit for both sides of your axles is part # 23-342-343. You will need one kit for each axle on your trailer. These are free backing 12" x 2" brake assemblies from Dexter Axle. Attached is a review video for you to check out as well.

  • Replacement Hydraulic Trailer Brakes for a 16 Foot Cronkite Utility Trailer
    Since you have Dexter hubs and you have the 5-bolt pattern to mount brakes, you can replace them with new Dexter hydraulic brake assemblies. For 3500 pound axles though you would not have a 5-bolt pattern and the assemblies would be smaller than 12x2 inches. So I do not think you have 3500 pound axles. If you can tell me the bearing numbers you have that will help me determine the axle capacity and the correct hub. The Dexter brake assemblies you mentioned, # 23-342 for the left and #...

  • Replacement Hydraulic Drum Trailer Brakes for Dexter 8-201 Brakes on a Towable Man Lift
    If the brakes in the picture are 12 x 2 inch brakes then yes, you can use # 23-324 (left hand side) and # 23-325 (right hand side). These brakes are rated for 5,200 pound axles and use the 5-bolt mounting pattern as the brake in your picture. The new brakes are also uni-servo just like the one brake in your picture. Something else in your picture is interesting. I believe the brakes on there now are free backing brakes. These brakes would allow you to back up without the brakes engaging....

  • Does Car Trailer with 7k Axles Need Free-Backing Brake Assemblies as Replacements
    If your car trailer has a reverse lock out solenoid on it then you wouldn't need free-backing plates and the part # 23-336-337 would be the set you'd need for each axle. If you do not have a reverse lockout solenoid on your actuator (two wires ran to the back of it) you'd need free-backing plates like the part # 23-342-343 so that you could back the trailer up without the brakes applying.

  • Free Backing Hydraulic Drum Brakes
    I have a solution for you but no, the Dexter Hydraulic Drum Brakes item # 23-336-337 would lock up every time you backed your trailer up. You need free backing brakes like the Dexter Hydraulic Trailer Brake Kit - Free Backing - 12" - Left and Right Hand Assemblies item # 23-342-343. These drum brakes are rated up to 7,000 lbs like the ones you were looking at.

  • Replacement Hub and Drum and Hydraulic Brakes for a Cronkite Tandem Axle Trailer
    Trailer hub and drum assembly # 8-201-5 does match your bearings. I am fairly certain you have 5,200 pound axles and not 3500 pound axles since all of the parts you need are for higher rated axles than 3500 pounds. The races come already pressed into the hub. If your wheels have a 6 on 5-1/2 bolt pattern then this is the hub for you. This hub and drum takes 12 x 2 inch brakes. The brake assemblies that fit and that are also rated for 5200 pound axles are # 23-324 for the left and # 23-325...

  • 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 to...

  • 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 Free Backing Surge Trailer Brakes for 6/7K Axle with Parking Brake
    I do have an option for you but none of our free backing surge braking assemblies in this size have a parking brake feature. That said, we do have a surge brake assembly option with parking brake with the uni-servo backing plates, the Dexter Hydraulic Brake Kit part # T2351300-200. If free backing is a must then I simply recommend using the Dexter Hydraulic Trailer Brake Kit part # 23-342-343 and forgoing the parking brake.

  • 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.

    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.

    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....

  • 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,...

    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 hubs.

  • 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...
