The Hydrastar electric-over-hydraulic trailer brake actuator applies pressure to your trailer's hydraulic brake system in response to the electrical signals sent from your in-cab brake controller. As a result, your trailer's hydraulic brakes will be activated every time you apply the brakes in your vehicle or press the manual override on your controller.


Pair the Hydrastar electric-over-hydraulic actuator with your trailer's disc brakes to get the best possible braking setup. With disc brakes, you already have more consistent braking at higher speeds and a shorter stopping distance than you'd get with drum brakes. In addition to more reliable braking, you also have less cost to maintain the brakes as there are fewer moving parts. Combine these benefits with an electric brake controller and you'll get greater control over your already superior brakes, providing you with the best braking performance.


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

With the Hydrastar 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 settings 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. You can also use the manual override on your brake controller, which allows you to engage the trailer brakes without having to apply the brakes in your vehicle. And perhaps most impressive, if you have a proportional brake controller, your brakes will be activated with an intensity that matches the braking speed and power of your rig.


This pump-and-motor-based system increases response time compared with traditional actuators because the trailer brakes are triggered when you apply the brakes in the tow vehicle, as opposed to when the trailer pushes against the hitch ball. This not only gives you faster, more efficient braking, but it also eliminates the pushing sensation that occurs in setups that use standard surge brake actuators.


Hydrastar actuators are also beneficial because, unlike standard surge couplers, they allow you to activate your brakes when reversing down an incline, such as a boat ramp. Having the ability to brake in reverse gives you more control and prevents wear on your tow vehicle.


Hydrastar Installation

Hydrastar Installation Diagram

This Hydrastar electric-over-hydraulic brake actuator will give you years of trailer-stopping performance. The actuator mounts on your trailer's frame with the included stainless steel hardware. The included 7-pole junction box with color-coded studs makes it simple to splice into your trailer's wiring and to connect the provided 7-way trailer connector. Once the actuator is correctly wired, you can connect your trailer's hydraulic brake lines to the 3/16" female port. Lines and fittings are sold separately.


Durable, Marine-Grade Construction

The Hydrastar Marine actuator is ideal for use on boat trailers. Just like other Hydrastar electric-over-hydraulic actuator models, this system is built of extruded anodized aluminum for superior corrosion resistance. The weathertight seals protect internal components from the elements. The Hydrastar Marine actuator also features marine-grade gaskets and stainless steel hardware that won't rust. These extra features make it perfect for marine applications.


This actuator also has a vented end plate that releases pressure, moisture, and heat to help prevent any internal damage. Unlike models that are unable to release heat and pressure, this vented actuator can be safely mounted inside of a compartment on your trailer. As a result, this actuator is great for gooseneck and fifth-wheel trailers where finding space on the tongue can be nearly impossible.


Breakaway Kit

Required by law in most states, a breakaway system will activate your trailer's brakes in the unlikely event that your trailer disconnects from your tow vehicle. This kit wires to the included battery and to the Hydrastar actuator. If your trailer separates from your tow vehicle, the breakaway kit signals the actuator to apply the brakes.


Brake Controller Compatibility

Not all electric trailer brake controllers will work with this electric-over-hydraulic brake actuator. See the following table to determine compatibility with common models of brake controllers. For best performance, it is recommended that you use an aftermarket electric brake controller rather than an OEM factory-installed controller.

Easy to install had an issue with my controller not working.
once I updated my controller it worked good.
Not sure how to recharge the battery will need to look into that

Put the product on an ambulance simulator used in training EMS personell. It was easy to install and worked as expected. We would order again if need came up>



by:

Good looking product. Everything was included as I expected, the length of the truck plug whip is a good length for a universal kit. All the colors for wiring in the box are also labeled, that was nice to see. That will help with installation time. This is being installed on a boat trailer with a swing away hitch so the hitch neck is short but it looks like everything will fit without getting it all wet.

I bought this as I was replacing a worn out surge brake set up.

I went with the electric hydraulic set up (after discussing options with Ricky S. Thanks!) as I wanted to address two issues: 1) better braking for an 8,500lb boat/trailer configuration; and 2) be able to use the Reese SC Weight Distribution w Sway Control set up with the Reese Pole-Tongue Adapter for Weight Distribution Systems.

This is an amazing upgrade! Backing up is now easy, I have brakes loading/unloading the boat on the ramp now, and vehicle stops better without the "pushed around" feeling that I used to get from the surge brakes. Additionally, it allowed me to make my vehicle safer by using the WD hitch as recommended by the manufacturer.

While this was a more expensive option that a straight surge brake replacement, it was probably the best few hundred dollars I've ever spent!



by:

This is the best brake setup I have seen or used on a trailer!!!
And I have 3 other trailers with electric brakes!!!
If I ever have a problem with them I will replace with the Hydrastar unit!!!



by:

Just finished installing have not took it out yet



by:

This is the BEST way to convert your surge brakes to electric. Pared perfectly with my 2014 F150 with the electric trailer brake option. Controls work great and this specific 1k PSI version easily handles my trailer and 21' SeaRay boat.



by:

Most of the items in this package were top shelf! The one exception is the 7 way harness supplied. The harness was not wired following standard the color code for trailer lighting. The red and yellow wires were reversed and the brown and green wires were reversed in this harness. This error consumed quite a lot of time troubleshooting the trailer lights until I wired the trailer and performed a plug pins to wire check and found the errors.



by:

This is an excellent device. After years of towing camping trailers with electric brakes, I got used to the control that provided: a bit of sway starts and all you have to do is activate the trailer brakes alone via the controller and everything settles down....so in comparison the surge brakes on my new 6000 lb boat trailer outfit were not doing it for me. Plus-- no trailer braking while backing down a slippery boat ramp?? So this was such a great solution. I can back down the boat ramp with full control at all times, and can adjust braking on the road with the boost and gain functions of my P3. Oh one thing- not all controllers work with this! Had to switch my Prodigy RF for a P3. I had the trailer brake system installed by my mechanic but I did the wiring myself. The light and brake connection outputs from my VW Touareg factory 7-way did not match the instruction's colour diagram but I figured it out eventually. Probably just a VW thing.



by:

Works as described.



by:

Well packaged and on time!



by:

Awesome product works way better than my surge brakes, the terminal connection box made wiring a breeze! Awesome customer support from E trailer.com to resolve a cracked hydraulic cap!



by:

hydrastar system has been the answer as we can back down the boat ramp with our tri-axle being able to have braking power in reverse. The product is every thing it was said to be and can not say enough about the system to our friends. We installed six new brakes and kit lines all from etrailer.com. The staff was very helpful, and would deal with them again.



by:

Only have taken one test drive, but it is so much better than surge brakes. No more slamming during takeoff. Much stronger than my surge setup. The install was straight-forward using the video and other folks pictures. I stole the stand idea from one of the other users here and it worked very well. I chose to drive bolts through the tongue to lock the existing actuator into place after removing the guts of it. This is because the tongue on my trailer is 3.3" wide and I would have had to get a new tongue welded on. This seems to do as good of a job with much lower cost. My only complaints are with the electrical box. It seems I received a much cheaper one that was shown in the videos. The bus snapped in instead of screwing/rivet and it kept popping out. The entire box cracked during the install, so I threw it out and bought another one from a local shop. Additionally, I didn't get the full compliment of connectors, instead they were already installed on the cable. The problem is I didn't need 8ft of cable, so I had to cut those off and go get other connectors. All in all, I am very happy with the EOH system vs surge and I would buy this again and again.

After a year, it is still my favorite trailer upgrade. I love that the tongue does not slam during takeoff. The brakes work great. I havent had any issues with losing brake fluid. My only two complaints: The cap came off during a road trip it was a torture test of 1000 miles, and I can say if it came off without help my son or a passerbyer in the parking lot. The backup battery died about a month ago. While it is relatively inexpensive $40, it was annoying that lasted less than a year. Not sure how long it sat on the shelf before install so your mileage may vary.



by:

The reason for 4 stars is in photo 1, the junction box is by far the cheapest and worst junction box I have ever had the pleasure of putting together, and I have installed many of them. My local suppliers junction boxes make this junction box look well let the imagination roam on this one, TERRIBLE. Again the break away setup in my opinion is sub par, not well built, though which break away system now a day's is they are all cheap. The 7 way harness as well is sub par, I have hand built better. The actuator, very interesting and a little different, not to sure about the quality, only time will tell, it does seem to be working and working well at this point. Stops trailer and tow vehicle on just trailer brakes alone, impressive.



by:

Installed this on my boat trailer so I could legally tow it for a trip to BC. It works great and E-trailer was spot on with their advice. Very happy with the delivery time and installation was a breeze.



by:

Awesome product. Would buy again and again. Easy set up. Bought this with kodiac disk brakes. I have a triaxle snowmobile trailer and also bought their triaxle line kit. Easy to install. Only problem was trailer wiring did not match up with the supplied plug. The plug was correct not the trailer. Easy fix though. Only other problem was 100% my fault. The disk brakes DO NOT come with bearings. They should. Would have saved me having to order them. Local auto supply shops did not not have six bearings and seals. If you have a drum brake trailer I would buy this just asap. Hit the truck brakes and the trailer stopped the truck. Had to reduce the power to the trailer. Slide the trailer brake lever and all six tires smoke.



by:

It took a lot longer to install the unit than I thought, and I am mechanically and electrically competent. Being there is no mounting hardware I had to purchase several bolts and fasteners to securely attach everything to my trailer. The color coding on the wire from the plug is not standard with anything. I found out the hard way and had to rewire the lights, brakes, and signals. After two days of constructing and installing the bracket and unit, I finally got to test it. It works great so far and much smoother and controllable than my old surge coupler. etrailer promptly sent everything in a strong box and it arrived in only a few days to Alaska from the date I placed my order. Great so far!



by:

The product seems to be of high quality. Easy to lay out and with some referring back to blueprints it was easy install . My biggest problem was wire color did not match. But a trouble light solved the equation . 2019 boat trailer I didn’t know there were different color codes . Still took a few hours to do it right. Pulled the boat 125 miles each way from home to lake and was pleasantly surprised at the steady brake response . So much better than surge brakes .



by:

great system, easy install, works so much better than surge systems



by:

Item must have been dropped one of the mounting brackets was bent and I had to straighten it out.

  • Recommended Weight Distribution System and Electric Over Hydraulic Actuator for Tug Boat Trailer
    I did some research and your F-150 with the combination you have is the 11,600 lbs if you have the max towing package. If you do not it drops to 10,600 lbs. The upgrades you have done to your truck are really nice so I can see why you don't want to change vehicles. What I recommend is keeping your current hitch, upgrading your weight distribution system to the Reese Steadi-Flex Weight Distribution System w/ Sway Control - Trunnion - 14K GTW, 1.4K TW # RP66561 because it will work well...
