Saltwater and road spray can destroy unprotected brakes quickly. These Dexter hydraulic drum assemblies use Dacromet-coated backing plates, e-coated shoes, and stainless steel springs to fight corrosion from the inside out. The layered coating system keeps the hardware and shoe levers protected even in marine or winter conditions, giving you reliable braking season after season.
Backing down a ramp or into storage shouldn’t mean fighting brake drag. The free-backing design on these 12" x 2" hydraulic drum brakes lets you reverse without the shoes engaging, even if your surge actuator doesn’t have a reverse lockout. You get smooth, easy movement in reverse while still maintaining solid braking when traveling forward.
When you stop on an incline, you want peace of mind knowing your trailer will stay put. These assemblies come ready for a parking brake cable connection, letting you add a tongue-mounted handbrake for extra security. A simple lever and cable setup locks the wheels when parked, so your trailer stays steady during loading or storage.
Over time, brake shoes wear and can lengthen stopping distances. These brakes use a manual star-wheel adjuster so you can fine-tune pad contact for maximum braking torque. Adjuster plugs keep dirt and debris out of the mechanism, helping the internal components stay clean and responsive through regular use.
Each assembly fits most standard hub-and-drum setups rated up to 7,000 lbs and mounts with a 5-bolt flange pattern. Designed for 14-1/2" and larger wheels, they deliver dependable braking power under heavy loads without compromising control or smoothness.

Hello, everybody. This is Jeff at etrailer.com. Today I'm gonna take a look at the Dexter 12 inch by 2 inch corrosion-resistant left hand and right hand free backing hydraulic drum break assemblies with the parking brake, and these are for a 7,000 pound axle. Now, these hydraulic drum brake assemblies are designed for use with a surge type trailer brake actuator. These we mentioned are a free backing design, and the free backing design lets you reverse without the trailer brakes being activated. And they do that because the hydraulic pressure is contained by the wheel cylinder and the brake shoe turns and releases pressure when it's reversing.
Now, the free backing design we mentioned, you can tell if the brake assembly has a free backing design, and the easiest way is you look at the primary shoe. The primary shoe will have a D shape to it, you can see right here, and that'll let you know that it is a free backing designed assembly. Now, the brake shoes themselves, they are lined with automotive grade friction material, and that friction material is fully bonded, not riveted to the shoes for a nice long life, more braking torque. The backing plate, if we swing this around, if you look at the backing plate, has a corrosion resistant coating on it. And the springs that are used in the assembly are stainless steel springs, so these assemblies are great for marine applications.
Now, the left hand driver's side, the right hand passenger side brake assemblies, and the way you can tell if they're left hand or right hand. Now of course, when you get a new assembly, it'll have a sticker on it that tells you that. But if that sticker wasn't on there, the easiest way to tell is you look at the length of the pad that's on the shoe. So if you look at this one, the pad goes from here down to here. And if you look at the shoe back here, it's all the way from here to here.
So the shorter pad is the primary shoe, and the primary shoe will always face the front of the trailer when you install it. So that means it's gonna be on this side, which is the right hand passenger side. And the same way on this other one, the shorter shoe is the primary shoe. That'll face the front of the trailer, so this will be the left hand driver's side assembly. Now, these are a manual adjustment brake assembly.
You can see the adjustment wheel down here at the bottom does require periodic manual adjustment. These do have the built-in manual parking brake lever, so they will work with a trailer that already has a parking brake. If you do want to add a parking brake, we also sell the frame-mounted brake lever and cables separately on our website. They're part number T-2385200, and they are listed on this product page as a related product. Now these do fit, if you turn it over, you can see the five holes here. They will fit a five-bolt brake mounting flange bolt pattern. And if you noticed the the nuts are included with the washers attached to them for installing them. These parts are made in the USA. Again, the specs fits axles that are rated at 7,000 pounds. Now, the size we mentioned is 12 inch by two inch. And what those measurements are, the 12 inch is the diameter. So if we measured a straight across here with a ruler, you'll be able to see there's your 12 inch measurement. The two inches wide is gonna be the width of the pad. So we put that, there's your two inch. And these do require 12-inch brake drums, and the wheel size that'll fit over these assemblies are 16 inches and larger. But that should do it for the review on this Dexter 12 inch by two inch corrosion-resistant left hand and right hand free backing hydraulic drum break assemblies with the parking brake.
