Heavy trailers demand confident braking. This Dexter hydraulic drum brake kit uses a duo-servo setup with dual wheel cylinders to provide strong, even stopping power in both forward and reverse. It’s designed for 9,000 to 10,000-lb axles and works with 12-1/4" x 3-3/8" hub-and-drum assemblies (sold separately), giving you reliable braking control when you need it most.
Keeping trailer brakes properly adjusted takes time and tools. These self-adjusting hydraulic drum brakes handle that automatically, maintaining performance and reducing maintenance. Once installed, they stay tuned for consistent braking without having to crawl underneath for periodic tweaks.
When your trailer is sitting for storage or during loading, you want it to stay put. This kit includes an integrated parking brake that lets you manually engage the brakes when parked, adding extra control and safety wherever you’re working or storing your trailer.
Installation is simple and secure with the bolt-on design. The assemblies mount directly to a 7-bolt brake flange and are compatible with 15" or larger wheels. Both left-hand and right-hand assemblies are included, giving you a matched set ready to bolt up for dependable hydraulic braking performance.

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Dexter 12 and a quarter inch duo server hydraulic drum brake kit assembly with parking brake levers. Now this brake assembly is engineered for trailers with 9,000 to 10,000 pound axles. This is going to fit most standard hub and drum assemblies, including Dexter and Lippert, and the wheel size compatibility is going to be 15 inches or larger. So this does feature a duo server servo design rather, which means that it has a dual plunger design that's going to give you consistent braking, braking force in both the forward and reverse directions.
And the self-adjusting mechanism here is going to automatically maintain proper brake shoe alignment. That's gonna reduce the need for manual adjustments. You can see by the cable here that goes around the pulley, the pulley's behind the braking lever. So it's probably hard for you to see, but that cable is going to go around the pulley and then connect to the lever down here. That's gonna automatically adjust the adjustment gear.
So self-adjusting brakes will automatically adjust to deliver optimum performance and braking power. So there's no need for manual brake adjustments and the proper adjustment's going to obviously lead to better brake efficiency and less wear on your tow vehicle brakes. This also, these also do have the integrated parking levers that are gonna allow you to manually engage the brake for extra security. Whether your trailer is packed with gear or sitting in storage, that feature is going to ensure that it stays put exactly where you left it, giving you peace of mind when parked. So you're gonna get the left hand and the right hand here as you can see, so left and right and the dimensions, the diameter, as I mentioned, 12 and a quarter inches.
The width three and three eight inches wide. And this is a seven bolt mounting flange bolt pattern. These are really constructed well, durable construction built to withstand rigorous use. So you're gonna, that's going to ensure long lasting performance and durability. We do also sell these separately as well, so you can find them separately here att etrailer.com if you don't need both left and right.

Good product, good availability, good price and great service. Is there any reason not to buy again from etrailers?
Much easier, faster and almost cheaper to buy the kit then replacing the separate Needed parts
After electric brakes this Hydraulic breaks works just super fine for moore then a one year electrical brakes i used to replace every 6 months!
This was just what I needed. The staff at etrailer was over and above helpful, knowledgeable and efficient.
I recently upgraded my trailer from electric drum brakes to hydraulic drum brakes. I found the Dexter Hydraulic Drum Brake Kit to be very easy to install, and it works very well. I was able to install the kit myself, which saved me a lot of money. The kit is well made and includes everything you need for installation, including detailed instructions. I am very happy with the Dexter Hydraulic Drum Brake Kit.
Parts received exactly as were needed. Etrailer customer service ensured my companies needs were met and exceeded. Great job as always.
brakes arrived faster than expected. They were an exact fit for my dexter 8k tag axle on my 1998 Bounder Motorhome. The price was very fair compared to other venders
I had some parts missing nuts/bearings and seals
Should have ordered the ones that had the dust covers on the back
