Three layers of defense against rust and corrosion: Dacromet, acrylic topcoat, and e-coat shoes. Parking brake ready, free backing brakes let you pick the best time to lock your trailer's brakes. Fits 14-1/2" and larger wheels.

Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that everything listed above lines up with what you need for your trailer, you can be pretty sure these will work for you.
Backing up your trailer might be the only time you don't want the brakes to work. Normally, this would be a job for the reverse lockout on your hydraulic actuator. But if you don't have a lockout, you'll need brakes that will you allow you to back up freely instead.
How do they work, you ask?
During normal forward braking, a fall-away shoe expands to catch your brake drum with enough force to bring your rig to a stop. When driving in reverse, however, these brake assemblies prevent the shoes from fully catching on the drums. This takes away your braking control, and allows your wheels to turn, without stopping them completely.
Note: Free backing brakes don't activate when you're in reverse. So, keep in mind that a trailer breakaway kit will not be effective if your trailer were to disconnect from your tow vehicle while you're backing up.
If you're looking to customize your off-road trailer or pop-up camper, these brakes can be a great way to do that.
Installing these brakes is easy, and using them is even easier. Run the linkage cable from your tongue-mounted handbrake (not included) to the lever on the backing plate of the assembly. Then, just pull on the handbrake any time you need a little reassurance that your valuable cargo won't roll away from you.
If your trailer is routinely exposed to saltwater, snow, or heavily treated salt roads, these are the brakes for you. You'll get the best corrosion protection you can get when it comes to drum brakes for boat trailers. The first layer of anti-corrosion coating is an e-coat primer applied to the backing plates and shoe levers. Next, a Dacromet coating with a 1,000-hour salt spray rating goes on. And finally, an acrylic topcoat that's nearly rustproof is put onto the backing plates. You'll also find the stainless steel springs inside that are virtually rustproof.
The more miles you put on your trailer, the more your brake pads will wear down. As they lose contact with the drum, stopping distances get longer and longer. To keep your brakes working great, it's important to adjust them pretty routinely. For this job, grab a floor jack and either a brake adjustment tool (sold separately) or just a standard flathead screwdriver.
Jack up your trailer enough to get the wheel(s) off the ground. Remove the adjuster plugs from the backing plate on the brake, and insert the flat end of the tool through the back of the assembly.
Push in on the star gear and lift it up. Keep doing this until the brake pads catch on your brake drum. When you can't spin your wheel by hand anymore, back the gear off by about 10 clicks (push down on the star gear). Does the wheel now spin freely (even if it sounds like the brake pads drag slightly on the drum)? Great! Then you're all done with that one and ready to adjust the rest.
Once you get these assemblies installed, and your lines flushed with fresh fluid, you'll need to break in these brakes. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.
Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

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.
