Note: Do not power wash the Hydrastar actuator or take it through a commercial car wash. High-pressure water may damage the seals on the actuator.


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 hardware. Then it splices into the trailer's wiring and connects to your hydraulic brake lines from the 3/16" female port. Lines and fittings are sold separately.


Durable Construction

Just like other Hydrastar electric-over-hydraulic actuator models, this system is built of extruded anodized aluminum for excellent corrosion resistance. In addition, the weathertight seals protect internal components from the elements.


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.


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.

Hydrastar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi - HBA16

Average Customer Rating:  4.8 out of 5 stars   (105 Customer Reviews)

Ordered the HBA16 to install on 2013 Dutchmen Rubicon 2900 TH with 7K Lippert axles, feeding the Kodiak Disc Brakes also purchased from etrailer. Unit was received with out any problems, installed and worked as advertised. The only real issue I had was prior to the order finding out for sure if this Actuator would work on my 2014 F-350 with or without the HBA-CAM. Once I received the HBA-16 the documents that came with it from Cargo Towing solutions provided me with another resource to verify what my truck would need. I contacted Nick Ruehlman with Cargo Towing Solutions and he assured me the HBA16 would work on 2014 F-350's with built in controller without the HBA-CAM. Installation was done by a brake tech and went in without any problems. etrailer customer support was very helpful in completing this project. Brakes are outstanding now that the electric's disc's are out.


Comments
The HBA16 is still performing well after 5K miles. Great product.

I have a 2015 GMC Sierra 2500HD Diesel, towing a 2017 Pinnacle 36FBTS 5th. wheel. The Pinnacle has a standard drum braking system. On a long trip this year I cracked both rotors on my truck from over heating related to the Pinnacle's drum brakes failing to fully provide proper stopping.
I decided no more, and after much review I replaced the factory drum brakes with the Kodiak Discbrake system. (my first time ever doing something like this) In addition, one of the key items for me was a way not to replace my on-board factory trailer brake controller, (did not want to use an aftermarket product, that would diminish the interior look ) thus I also added the control Adapter Module that enabled me to use the factory installed brake controller. With all this change I decided to also go ahead and add a separate brake away battery. Everything I just described are shown in the attached photos.

I found eTrailer extremely helpful in answering questions, although I did not have a lot of questions since their online videos proved most helpful.

All parts of the Kodiak system worked fantastic following a 2500 mile trip. The improved braking is superior, and I did not need to replace my on board controller, but continued to use it by installing the control adapter. The disc brake picture is one of the disc brakes that I examined following our trip...all in perfect shape with everything working great for the entire trip.

Working great as well as it did since installation
Morris G - 07/26/2021

by:

I've been using this brake controller with a disc brake conversion I got from Kodiak Trailer Brakes for about a year and the results have been fantastic. Prior to doing the disk conversion, I'd been through about 3 sets of the old electric drum brakes on my 18,000 lb. dual axle toy hauler and I'll never use drums again.

The stopping distance is noticeably shorter and I anticipate the maintenance to be super simple since they are discs. The electric controller takes some getting used to since there's about a 1-1.5 second delay between hitting the pedal and the brakes engaging. That can be a little unnerving until you get used to the fact that when the brakes come on, the REALLY come on.

After owning my toy hauler for ~10 years, this is easily the most important modification I've done. I will be stripping off brand new drum brakes on my next trailer and replacing them with discs before even the first trip.




by:

Couldn't be happier with this brake system along with my Kodiak disc brakes. System works perfect.


Comments
Love love this brake system, going to put one on my other trailer I’m restoring.
Eddie - 07/01/2019


by:

The HydraStar unit worked fine, easy to install and hook up.
I hauled several 10 ton loads of hay with no problems, after replacing a brake controller that was defective, I got another controller that was supposed to be compatible with electric/hydraulic brakes but wasn't, a newer one of the same model was compatible.
E-Trailer lived up to their slogan, great products,low prices and they have good service too.



by:

I have put three on these on different trailers and they work great!! They install easily and stop on a dime!! I highly recommend the purchase of the optional HBA-CAM. All the newer trucks can be a little tempromental with the intergrated brake control box. I have an "09" GMC 3500HD


Comments
Thanks for your business and your review, Chris! For your reference, the # HBA-CAM
Hydrastar Electric Over Hydraulic Actuator Adapter Module for Ford and Chevy Brake Controllers
$134.99
is a required rather than optional add-on for 2007-2015 Chevy and GMC trucks and will not work with the OEM factory-installed brake controller.

I installed this product on my fifth wheel RV about a year ago. I tow with a f350 drw truck and was always concerned with the way it stopped. Now there are no issues. Best upgrade I have ever made. Product was excellent. Product arrived as promised. customer service was great. Thanks etrailer



by:

I've towed my boat over 4000 miles this year and the electric over oil brakes have performed better than anticipated. The safety and control that I have with this system could not be better.

by:

It was the best upgrade for a new brake system I was replacing the old electric brake!



by:

good quality how ever it should be designed to work with all brake contrlers



by:

This is a solid well built unit. Great screen makes it really easy to read. Lots of configuration options to tune it just the way you like it. Comes with extra parts for various mounting uptiond. I purchased a wiring harness specifically for my vehicle to make things nice and easy. Love this controller.



by:

I have been towing 5th wheel trailers since 1992 with electric drum brakes and finally switched to electric/hydralic brakes after I don't know how many close calls while towing loads. I wish I would have done it a lot sooner, I cannot believe the braking ability I hope never to own anything else. Great customer care during the process.



by:

I purchased the HydraStar Electric over hydraulic actuator for disc brakes. I have been very happy with this purchase. Product arrived very quickly . Instructions were clear and installation went smoothly. Brake system is working great for me on my equipment trailer.


Comments
Unit it working well. I am very happy and satisfied with this unit. Thank you

Well built unit. Have to see how it performs- waiting for line kit



by:

I just received eoh trailer brake actuator. I will be installing it soon on my triaxle boat trailer, packaging is in good condition, so the actuator should work as intended. Service is outstanding as usual, shipping was excellent. If the Canadian dollar was i stronger i would certainly make more purchases from E-trailer. Thank you


Comments
The actuator worked great last year traveled over 5000 miles with it. As of late last fall my boat was stored on my trailer and because of covid19 the marina here on the east coast of Quebec wont open for another 6 weeks. The actuator was wrapped in plastic to protect it from the harsh winter here close to the ocean. I expect and need it work as it my trailer has to be certified road worthy to pull it on the public hwy. I will give you an up date in a couple of months. thks

product showed up on time in working order, but was aesthetically damaged, the mounting tabs were bent and scratched ,it wasn't during shipping because the box was undamaged , so i would return it as its going on a 75k $ dollar polo trailer but my customer needs it asap the free shipping was nice , but would have gladly paid more for an undamaged actuator.


Comments
Great

by:

Very well assembled and top quality. Not excessive in size and fits easily in trailer. Extremely easy hookup and straight forward to do using instructions. Wired into existing break away and 12v RV battery'


Comments
Always works. Extra bonus was when I realized I could pull the release pin and hook up the fifth wheel without pushing the trailer up on the chocks or wheel lock so much.
Albert - 04/06/2020

I have taken a trip from Mich
to the
black hills and back. Put around 3000 mi. On the fifth wheel since I converted it to hydraulic brakes. The hydrastar actuator worked great as well as th he kodiak brakes. I wish I would have converted it long before now.
Hydrastar and Kodiak is the only way to go



by:

I changed out my electric drum brakes on my Montana fifth wheel with this hydraulic brake actuator and Kodiak discs rotor system . What a difference this new brake system has made. I can now lock down the trailer tires if needed and drive much more relaxed on the highway knowing I can stop on a dime.



by:

I upgraded the 32" 12,000 lbs rated trailer to Electric/Hydraulic as the electric brakes really were not doing very much to help slow the trailer down. The overall upgrade included new 7,000# axles as well as this hydraulic converter next to the winch in the front of the trailer. If I ever get another trailer, this unit will be spec'd into it



by:

As for the product, Hydrastar HBA16, it’s great. Have lots of trouble-free experience with this model on my ‘07 trailer up until I bought a new 18 Ram 3500. Had compatability issues so I bought the newer updated model as recommended by Hydrastar. Installation was easy except for the new mounting hole spacing had changed so I had to drill new mounting holes on my trailer. However, unit works great, as expected. Hopefully I will get at least 12 or more years of trouble-free use and service out of this unit as I did the previous one.

As for eTrailer, the shipping is always fast and the prices are great. However, the packaging on this order was not great. The unit was basically wrapped in brown paper and tossed in an oversized box. When I received the package there were holes in the box where the unit poked through during shipping resulting in the mounting brackets being bent on both ends. Thankfully I was able to straighten them and there seems to be no functional damage to the unit itself. On that issue alone I am a bit disappointed with my experience on this transaction with eTrailer.



by:

The unit failed after about one month. I called etrailer and they gave me the info to file a warranty claim with the manufacturer. The manufacturer had a replacement to me in a day and a half with a shipping label for the bad one. The replacement has been solid for 11 months with 60,000 miles on it. This was a great upgrade! It’s worth the money. Braking is so much better. I use this on a 33 foot 16,000 flatbed for work. I can stop with confidence every time now.



by:

Have been using this brake actuator for a year now with absolutely no issues. Other people who have committed on how much better my trailer brakes better than theirs. I’m looking at ordering another one to be placed on a trailer I’m changing the axles out on. I’m going from electric brakes to the hydraulic brakes. Great product



by:

This actuator along with the Kodiak disc brake kit has improved the stopping function and shortened the distance substantially.
