Heavy-duty and easy to use, this surge brake actuator engages your trailer's drum brakes. EZ-Latch coupler makes coupling almost automatic. Primed and ready for a custom paint job after the actuator is welded or bolted on. Made in the USA.

If your trailer isn't married to just one tow vehicle, this Demco actuator will be a great option for you. Just keep in mind that because it doesn't have a reverse lockout on it to keep your brakes from locking up, you will need to have free-backing brakes instead.
Few things matter in towing as much as a secure connection to your hitch ball. The thing of it is, some coupler latches don't really have a way to show you that they have a firm grasp on the hitch ball. You either just have to eyeball it or try to wiggle the coupler latch until it closes. And if you opt for just trusting your coupler and assuming it's on there, you might not notice the gap between the ball and your coupler's ball socket, an issue known as highballing, until it's too late and you lose your trailer on the highway.
That won't be an issue with the EZ-Latch on this Demco actuator. Just center your coupler over the hitch ball, and lower your trailer tongue as you normally would.
As the coupler's socket slowly accepts the hitch ball, you'll see the latch rise. Keep lowering your trailer tongue until you hear the metalic clink . When you do, you'll know for certain that you've got a good, strong connection, without the need to tug or wiggle the latch into place. This gets you on the road a little bit quicker and with a lot more confidence.
The EZ-latch is so easy to use that you don't even need a safety pin to keep the ball secured inside the socket. But you can, as a theft deterrent, put a locking pin through the dedicated hole on the side of the coupler.
You might see the phrase "hard plastic" and think, how durable could that really be? But the truth is, it's tougher than it looks and you'll probably never break it.
Its real name is acetal copolymer. It has a self-lubricating surface. It's extremely resilient, durable, and smooth. And it wears well over time. In fact, this same can even be found in some automotive applications, making it perfectly suited for a telescoping brake actuator on a boat trailer.
When you slow to a stop as you're towing, momentum pushes your trailer toward the rear of your vehicle. When this happens, the surge brake actuator compresses the master cylinder inside, which forces it to push hydraulic fluid out to your brake lines, ultimately engaging your trailer brakes. When you start moving again, the actuator will telescope back out, stopping the flow of fluid back to the brakes and allowing your trailer's wheels to start rolling again.

Hi everybody, Andy here with etrailer.com. And today we're gonna take a look at this Demco Hydraulic Drum Brake Actuator. Now this is a DA10 hydraulic actuator that will activate your trailer's brakes when your tow vehicle slows or stops. And as you probably know, when you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer towards the rear of your vehicle. With surge brake systems, the hydraulic actuator is triggered as your trailer moves forward once your tow vehicle starts to slow down. When this happens, this actuator contracts applying force to its master cylinder.
This in turn is going to supply the necessary hydraulic pressure to engage the brakes on your trailer. Now this is a bolt-on or weld-on insulation onto your straight three-inch wide trailer tongue. And I wanted to mention that if you're bolting this on, this does require 1/2 inch by 4 1/2 inch grade five bolts for bolt-on mounting. This is made here in the USA of a heavy duty steel construction with a prime finish and a gross towing weight capacity of 12,500 pounds and a maximum tongue weight of 1,250 pounds. Now this does feature the easy latch coupler mechanism for simple secure hookup and disconnect.
You're going to be able to hook up to your 2 5/16-inch hitch ball when this latch is in the closed position. And I want to give you a brief demonstration of that. So I have my 2 5/12-inch hitch ball here. And as you can see, I have my latch in the closed position. And so, as you can see, that's going to allow you to easily latch onto your hitch ball.
So you're just going to drop the coupler over that hitch ball and it's going to snap right in place. And then to disconnect, I'm just gonna lift this latch up and that's gonna allow for easy disconnection. Now this does feature a composite master cylinder and this is durable and efficient. It's glass reinforced nylon construction is going to resist rust and corrosion. And the large reservoir is going to provide increased capacity for brake fluid.
The large automotive style diaphragm cap creates a completely enclosed system that's going to help prevent the contamination of your brake fluid. Now this has an aceto liner here, copolymer lining that's going to give you that smooth operation as this actuator telescopes in and out. And this also features a breakaway cable. And this has a snap hook to ensure a secure connection to your breakaway lever, which is right here. And this is going to hook to your tow vehicle and prevent a trailer runaway situation. So if your trailer unhooks from your tow vehicle, this cable is going to pull that that lever and activate the master cylinder to apply the brakes to keep it from a runaway situation. Now I do wanna mention that because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with free backing brakes so that you can drive in reverse without this actuator triggering your trailer brakes. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
My trailer coupler came with instructions. The hydraulic brake actuator coupler came with no instructions. Wish it were the other way around.
I ordered a brake actuator for a trailer that we use at my work. The original actuator showed to be available when I purchased it, but actually had been discontinued. A lady, whose name I will not mention, was very helpful and knowledgeable when explaining the situation to me. She offered a replacement to the original one, and even helped me with the cost. The alternatives were a little more expensive. Thank you Diana H. for your expertise and kindness!
