Dexter DX Series Actuator

The Dexter DX Series electric-over-hydraulic actuator is a dependable choice for your trailer braking needs. It is capable of up to 1,600 psi of pressure output to provide strong stopping power for your disc brakes. The lightweight, corrosion-resistant housing has fins and vents built in to shed excess heat. Inside the housing, the unit features enhanced wiring protection, allowing it to detect dangerous current levels to prevent damage from surges or improper wiring. Another internal highlight is the solid-state electronics, which regulate the actuator's electrical components to ensure consistent performance. All of this is cleanly secured within the aluminum housing by stainless steel fasteners, while Goretite seals protect the internal electronics from exposure to water and other elements. The DX series also remains compatible with most aftermarket and OEM-integrated electric brake controllers on the market.


Electric-Over-Hydraulic Actuator vs. Standard Surge Brake Actuator

With the DX series electric-over-hydraulic actuator, you can get all the benefits of towing with an electric brake controller while using hydraulic brakes. Because this actuator will activate according to the setting you have chosen for your brake controller (sold separately), you will have more control over when and how your trailer brakes engage. Depending on the features of your brake controller, you may be able to control both the rate and intensity with which your trailer's brakes activate. If you have a proportional brake controller, your brakes will be activated with an intensity that matches the braking speed and power of your tow vehicle.


This gives you multiple benefits over a standard surge-type actuator. Your trailer's braking will be tied to the braking activity of your vehicle instead of the momentum of your trailer. This will help to limit stress on the tow vehicle, and it will give you the ability to reverse without the trailer's brakes kicking in.


You can also activate the manual override on your brake controller to send out full braking power to the actuator. This will activate your trailer's brakes with full intensity. This is especially useful when traveling down steep hills with a fully loaded trailer. In instances like this, the trailer may require maximum braking power to avoid a jackknife situation.


Large Brake Fluid Reservoir and Self-Priming Pump

The large brake fluid reservoir in this actuator ensures that there'll be enough hydraulic fluid to handle a single-, tandem-, or triple-axle trailer regardless of its size. A self-priming pump reduces the time needed for bleeding the brakes and prevents the brake fluid from emptying back into the reservoir when the actuator is not in use.


Dexter DX Series Actuator Installation

Before installing this actuator, be sure that you have an electric brake controller with an output capacity of at least 5 amps.


You will also need enough 3/16" diameter automotive brake line (sold separately) to connect the unit to your brakes.


Mount the actuator level and upright in a dry area on your trailer. It is recommended that you mount the actuator near the front of your trailer. Do not mount it near the trailer axles or at the rear of the trailer.


The Dexter DX Series actuator splices into your trailer's wiring. Follow the diagram below when connecting the wires. 12-Gauge wire is required, but 10-gauge wire is recommended to ensure the best performance.

I have had these on a few trailers now and they work great. However this time I had to purchase another component to make my 2018 GMC sense the brake actuator was there. I’m not sure if they have corrected this yet however my buddy recently purchased the same from etrailer and it worked perfect on the same year exact same truck. Other than this it’s a great product.

When the OEM steel brake lines wore out on my boat trailer I decided to upgrade the surge brakes to electric over hydraulic (EOH). I replaced the damaged lines and wired up this Demco actuator and now I can stop my trailer on a dime -- should have done this 10 years ago. The actuator works flawlessly with my 2017 GMC's built in controller -- nothing else was needed! Please note though that the GM controller does not apply the brakes when depressing the pedal if the vehicle is not moving (duh). So don't be surprised if you try to test it sitting in your driveway and think that it's not working -- it's designed that way to save wear on the pump if you're not moving. Pressing the manual control does apply the brakes though. (The brakes also apply if you're on an incline). I fabricated a mounting plate out of 3/8 aluminum since the trailer tongue was not wide enough and attached the pump using 4 countersunk 1/4" stainless bolts and then used two 1/2" square u-bolts to affix it to the trailer. If I set the gain on the truck to max, I can actually lock the trailer's wheels, something that surge brakes can't do on their best day! Back in 2010 I upgraded my disc brakes to Kodiak all stainless steel rotors, mounting plates and calipers -- 8 years old and they were still like new -- also well worth the money!


Comments
Every trailer should be set up like this! Imagine power disc brakes on the trailer, just like your car. Theres a reason that drum brakes arent used anymore. Trailer manufacturers are just too cheap to build then right. Heres your opportunity to fix that!

Together, I couldn't be happier with my setup. The Dexter K71-651 provides more than enough power to stop my little single axle boat trailer and when the emergency break-away is activated, I can't roll the tires by pulling forward, they lock solid. I love the combination of this unit with the Redarc TowPro Elite, and these two have completely changed the way my trailer handles. If I was starting over, I would buy exactly this setup again. Thank you to ETrailer.com for excellent customer service and quick shipping. I received my unit in 2 days, and my entire order was exactly as purchased. They even emailed me on the day it was delivered to ensure I received it!

I installed this system on my 18,000 lb tri-axle boat trailer. Installation went very well and everything seems to be a great fit. I will not hook the truck to it until spring but I am very anxious to see the improvement over surge brakes. I was able to make a neat clean install and wiring directions were great.

Only 3 stars because the unit is not repairable. After a lightning strike nearby may be what damaged my controller I had to get a totally new unit. Upon opening the old unit up I could see there was just one component on the circuit board that was damaged. There should be an option to buy just the circuit board along with a gasket kit. It is a very expensive unit and I question the durabilty of the unit. There is a warning in the instruction manual that warns about sensitive electronics and also says the complete unit must be REMOVED from the trailer before any welding repair is made. If this thing is so sensitive you had better hope it does not crap out when you need your trailer brakes the most. I wish there was another option other than this "SENSITIVE" piece. etrailer was OK to buy from no issue there.

Item was very easy to install and seems to be working well. I was surprised at how loud the unit is under full activation (e.x. pulling the breakaway switch). Also I found out the hard way that I needed a heavier high temp breakaway switch, as mine started smoking and the wires started to melt when I puled the breakaway during a test. I ordered the Dexter K71-691-00 switch to hopefully resolve the issue.

1600 PSI electric over hydraulic brake actuator -- very easy installation. Brake Fluid reservoir holds quite a bit and made bleeding the brakes an easier task. Kudos go to eTrailer.com for their quick delivery of the brake actuator - Juanita T was especially helpful in both the selection and follow-up on the product. Special thanks go to her.



- K71-651
by:

This actuator does exactly what it's designed for. The wiring is very heavy duty and the instructions for connections are printed right on top. The cast aluminum end plates make mounting very easy and the self-priming pump made bleeding the whole system about a 3 minute project. The large reservoir holds plenty of spare fluid and the pump modulates the braking performance in perfect sync with the signal coming from the pump. My Prodigy P3 controller has a setting specifically for hydraulic pump control and it works very will with this pump.

Works perfectly, I've had it a year now and it's a quality part hooked right up and is still running fine . I never have a problem with anything I buy from ETrailer



- K71-651
by:

Easier install than the Titan controller that went bad on me. The videos show one person for the bleed of lines. It really needs two. One to operate the pump and one to bleed. I tried myself, but after bleeding 2 lines the pump started to make noises. Hurried to shut off before it ran too long. It works fine after the whole installation was done.

  • How Does Air Get in Hydraulic Trailer Brake Lines Every 2 to 3 Months
    Air can get into hydraulic brake lines from a leak in the line somewhere or at a fitting, via the cap on the master cylinder, or at a leaky wheel cylinder. A leak that is slow can be hard to find but it could eventually drain the master cylinder causing it to push through air. You would notice low fluid levels when you go to bleed the brakes if a leak was left unchecked for long enough. You would probably be able to find a leak when bleeding the brakes simply because there is more pressure...
