The EZ-Latch coupler makes hitching to a 2" ball simple and foolproof. You don’t have to hold a latch open or guess if it’s locked—just drop the coupler onto the ball and listen for the metallic “clink.” The latch snaps into place automatically, giving you a solid connection without tugging or re-checking. A locking pin can be added through the dedicated side hole if you want extra theft protection. It’s an easy way to know your trailer is secure before you hit the road.
This actuator’s heavy-duty steel body is zinc plated for marine-grade protection that holds up twice as long as standard coatings. The 200-hour salt spray rating means it’s made to stand up to water, road grime, and years of use without flaking or rusting. Whether you store your trailer outside or launch in saltwater, this finish keeps it working smoothly and looking clean for longer.
Inside the actuator, a heavy-duty plastic liner made from acetal copolymer keeps the moving parts gliding freely. It’s self-lubricating, so it stays smooth without constant maintenance and prevents metal-on-metal wear. That gives you consistent braking force and an actuator that telescopes easily each time you slow down or pull away again.
With an 8,000 lb gross towing weight and 800 lb maximum tongue weight rating, this surge brake actuator gives plenty of margin for most drum-braked setups. Bolt it on top of a 3" wide trailer tongue using three 1/2" x 4-1/2" Grade-5 bolts (not included) and you’re ready to tow. The built-in breakaway cable with snap hook adds extra security if your trailer ever disconnects on the road.
When your tow vehicle slows down, the Demco actuator compresses its master cylinder and sends hydraulic pressure to your drum brakes—no electric brake controller needed. As soon as you accelerate again, it releases smoothly so your wheels roll free. It’s a straightforward mechanical system that delivers dependable braking power trip after trip.

Excellent product to replace my old failed unit. The cost of this made my old unit prohibitive to fix.Thanks etrailer.
The right product for the right price. The installation video makes a simple job more complicated. Instead of two bolts very difficultly installed from the inside out, a single through bolt works fine.
Works a lot better than my original 2002 actuator. Boat actually slows down when I stop the truck. Easy to install. Blew the old fluid out of the lines with air compressor. Access to the piston made it easy to bled the lines.
Though I love the Demco hitch on my other boat trailer, this one was listed as a drop-in replacement for a Titan Hitch, and though the holes are 3" apart, they are cut about 1/4" too low. I will be reaching out to return this and exchange it for a Titan brand replacement.
Great product. So glad to find something that was just bolt on to this old trailer I was fixing up.
This brake actuator was an easy replacement to my previous 1996 Tennessee boat Trailer actuator. I did have to get creative with the line plumbing do to the change in angle. Also needed to change the lock to a pin lock. I like the latching feature and overall quality. I would not hesitate to make this purchase again.
i bought this to replace a Dico actuator, had to cut the dico off, and drill holes for the new one. Worked out great.
Replaced my obsolete Atwood actuator with this Demco DA70 model. Also purchased along with it the reverse lockout solenoid since I don’t have free backing brakes on the trailer. My plan is to use a 7 pin plug allowing me to wire the solenoid to the centre reverse position along with the other 4 wires used in basic trailer light wiring. Very pleased with my purchases.
Perfect fast ship , beyond cost effective and I was able to downsize to 2 inch ball. Naomi was awesome. Give her a raise
Installed, have not bled brakes yet but should work, Replaced my old welded on Attwood, lot of work removing the old set up. I think it will work perfect. Super fast shipping!
Very friendly company, customer service was very knowledgeable and helpful. The part arrived in just a few days.
Excellent hitch my trailer actually stops now replaced my old atwood. You do have to drill a 3rd hold of replacing an older Atwood but it's not had. Bleeding brakes was also easy, Just pump the emergency pull line with vice grips and put a screwdriver underneath to lock the pressure on. Then run to each wheel (furthest first) crack the line until bubbles stop and boom your good.
Nice and tough.happy with the purchase b
Excellent!, wonderful
working very well, I really like how it just drops on and hooks up
Great hitch, easy install. Seems to be heavy and well built.
nice heavy duty well built actuator, a little modification from my prior actuator but, doable.
Thanks
Item is heavy duty and well made. It fit perfectly over my 3" trailer tongue (after much grinding to remove the old welded-on actuator).
Item could have been better packed for shipping. It is quite heavy, but had only wadded up paper to cushion it.
It bounced around in transit and the plastic plug protecting the output port of the master cylinder was damaged,
Works cool
This component we had to replace the brake master cylinder in because of a manufacture defect in the installation of the brake line fitting. etrailer gets 5 stars! erailer was great to work with and we were up and going on the project quickly. Great example of how they address issues that arise in life. 4 stars for the part since it made it past the factories quality control without them catching th defect.
We purchased these parts for a custom build trailer for hauling heavy tool boxes over steep grades. Since completion of the build about a year ago, we have been using it and put a lot of miles on it. The hydraulic surge brake system makes it worry free. We can tow it behind different vehicles of differing weights and wheel bases and not worry about setting trailer braking, it is very nice. We will continue to use etrailer for our trailer needs.

Although there was a bump in the road with a cross threaded fitting from the manufacturer, Etrailer was fantastic to work with and resolved the issue very quickly and very generouslyfairly. The actuator works great and I really like this particular design. The brake works exactly as you would expect and it is nice since I don’t have to worry about electric brakes, gain adjustment, or changing surfaces or loads. It makes it a very user friendly set up and ifwhen I build another trailer I will likely use this or similar designed brake actuator.
Do you have a question about this Brake Actuator?
