Note: 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 the actuator triggering your trailer's brakes.


When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward 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, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage your trailer's brakes.


eZ-Latch Coupler

The coupler portion of this trailer brake actuator features a simple-to-use latching mechanism known as the eZ-Latch. With this mechanism, hooking up is as easy as dropping the coupler over your trailer hitch ball. The latch does not need to be tugged or manually activated to allow the ball into the coupler socket, nor does it have to be secured in place. Just make sure that the coupler is properly lined up with the ball when you lower it, and the rest is automatic.

In addition, the composite master cylinder is made of corrosion-resistant glass-reinforced nylon to further ensure durability.

Video Transcript for Review of Demco Brake Actuator - Hydraulic Brake Actuator - DM8102511

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Demco hydraulic brake actuator. This is a DA10 hydraulic actuator that's going to activate your trailers hydraulic drum brakes when your tow vehicle slows or stops. So if you're not familiar with the way an actuator like this works, you will be hooked up to the hitch ball on your vehicle. And then as you're pulling your trailer along, if you slow down or stop, your trailers momentum is going to continue forward, it's going to compress this which has been going to pump the hydraulic fluid to your brakes and cause them to apply, so that your trailers rights will apply for you. This will bolt right on to your straight three-inch wide trailer tongue that will require half inch by four and a half inch grade five bolts for mounting this in place.

Those are not included. You'll have to provide those yourself. But up here at the front, is our easy latch coupler mechanism. That's going to allow for a simple secure hook up to a 2 5/16-inch hitch ball. So very easy to get hooked up.

You can leave the latch close to just drop it down onto your hitch bar. It's going to automatically wrap around and give you a nice secure connection. And then to disconnect, simply raise the lever to open it up and then raise your hitch up off of your ball. This does have a built in four-inch drop to help you match your towed vehicles height. It is constructed of a steel construction, nice heavy duty steel construction.

So it is going to give us a gross towing weight capacity of 12,500 pounds. That is of course the weight of your trailer plus the load included. And a maximum tongue weight of 1,250 pounds, that's the weight pushing down on your hitch ball. That steel construction does have zinc plating. That's gonna offer corrosion resistance.

It's tested to 200 hour salt spray rating. So it is going to hold up really well for you, especially if you're gonna be out in the winter and dealing with salt, and just your typical conditions. Being out in the open, it's gonna hold up well. Our composite master cylinder is going to be durable and efficient. It is going to have a glass reinforced nylon construction, so it will resist rust and corrosion. It has a large reservoir that's gonna provide increased capacity for your brake fluid. The automotive style diaphragm cap is going to create a completely enclosed system to help prevent any contamination of your fluid. This is going to also include this breakaway with the snap here. So you'll snap that on to your tow vehicle, typically on to the same areas. Your safety chains, just get that and put in place. And then if for whatever reason, your trailer would become disconnected from your tow vehicle, this is going to stay connected and it's going to pull forward to activate your brakes so that your trailer is not bouncing down the road on its own after becoming disconnected. So a very important matter that is going to be required by law in most states. So having that included is going to be one less thing that you have to worry about. This is going to have a nice smooth actuation telescopes in and out. So we'll do a good job for you there. There's made here in the USA, so you can trust it's made to the high quality standards. We've come to know and trust for products that are made here in the US. One thing to note. Because this actuator does not include a reverse lockout, it is recommended that you clip your trailer with free backing brakes so that you can drive in reverse without the actuator triggering your trailer brakes. Because as your trailer or your tow vehicle pushes into your trailer, that would cause it to compress as if you're stopping. So you wanna make sure that your trailer is equipped with those free backing brakes so that you can still move backwards when needed. So that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
