What a difference disc brakes make compared to drums. Highly recommend the upgrade. Works great.


Electric over hydraulic brakes on my Eby cattle trailer would not work when hooked to my 2011 3500 Silverado pickup equipped with factory brake controller. I installed the Hydro Star HBA-CAM that I purchased from etrailer. Problem solved. Took 15 min. to install.


Have not tried it yet but received in a timely manner.

The brake actuator has been working just fine. I had a different brand on my other trailer and had nothing but problems with it. This one has been worry free.

@MichaelS Great to hear. Thank you for the update on your experience.


Just like advertised. Quick connection of 2 wires and GM controller sees the Disc brake actuator. This is in a 2014 Chevrolet Silverado 3500HD and 2008 DRV Mobile Suites 5th wheel.


A 2008 GMC 2500HD Deisel truck will not recognize a trailer unless it has this add-on. It did the trick very nicely. Just wish the mechanics at GM new this before we tried almost everything else!!


I'm sure it is a great product- I wouldnt know. I had a specific project planned and the tools and machinery to complete that project. It tool months to get this and the associated electric/ hydraulic booster. Hope to finally getting around to utilizing the $[XX] worth of parts next month. I reached out to customer service and they had no desire to even discuss the misleading lead times. Unless something has changed, if you need it fast, check elsewhere. I was very disappointed with etrailer on this one.


Fast delivery, installation instructions were easy to follow, nice wiring diagram. I would recommend and have found eTrailer easy to work with.



Still working perfectly.


EXACTLY what I needed for my 2019 GMC Sierra 1500. Boat trailer with EOH brakes wouldn’t work consistently for me, and this fixed the issue.

Trailer company had installed some type of off brand box that was supposed to perform the same function. It did not.

Installation - I didn’t mess with splicing wires. Simply ran wires into trailers junction box, crimped on eyelets and hooked to ground and trailer brake terminal posts.


Product was delivered in an empty box with one end cutoff. Obviously someone in the shippers network needed it more than I did. Called etrailer and they immediately shipped a new one out. Can’t ask for better service than that. I appreciate how they take care of their customers. I’ve used etrailer a lot over the years because of how they treat customers. Well done etrailer, we’ll done!


Delivery time was quick, ordering was smooth installation was simple, as of 6/1/2022 device is in staled on a 2022 Gatomade 40' gooseneck ( with electric over hydraulic brakes ), pulled with a 2007 ford f550 ( with an electric only factory controller ). it seems that this device has corrected the trailer disconnect and tbc fault warnings on the dash. I am using the original TBC. I have not many miles on since install but did test in parking lot and a short test drive. and as of now my previous statement stands. If this changes I will post a new review.


We have a cab and chassis 1 ton This part made our hydrastar basically plug and play. Super easy to install! Our truck came with a built in electric brake system and it would not “talk” to the trailer brake system. This prevents having to put a different brake controller in the brand new truck!!!



Bought a new Dodge and it still works great!


I haven't opened the package yet, but I wanted to comment on the outstanding customer service provided by etrailer. Pat C. assisted me via telephone with some questions that I had about the product and its description. Pat was very knowledgeable about the product and was able to respond to all of my questions. Pat then kept me informed of my order progress from that day to delivery. It was just a great purchasing experience. Thank you Pat C.!



We installed the CAM into our 2018 Ram 5500 Laramie. Normally we have seen these devices installed in the trailer near the hydraulic brake actuator. We decided that installing it in our truck, we could tow other trailers that had disc brakes too. We just put a small toggle switch inline to be able to add or remove the CAM to the 5500 brake circuit. We just turn the CAM off when we are not hooked up. This arrangement and part works perfectly. The design of the CAM allowed for a very neat and easy installation. Excellent product one year in use.


Got the parts all installed and they work good!


Great customer service!


Worked perfectly on my 2015 GMC Sierra.


Etrailer is the best.


Worked great and etrailer was excellent to deal with. This part was required when using Hydrastar electric/hydraulic trailer brakes with a Chevy PU. Very simple installation which I did in a parking lot when my new boat came off the barge



No problems after a year. I also bought a new Ford F-350. While the adapter is for Chevys, it works fine with the Ford as well


The integrated brake controller did not recognize the trailer until I installed the Hydrastar adapter. It was a very easy installation and now the built in controller works as it should

Product worked as advertised to provide interface between factory GM brake controller and Hydrastar actuator.

Good instructions and easy to install.

My Carlyle hydraulic system was installed on my 2008 Silverado HD 3500 dually by MOR-RYDE. The brake system would not connect to the truck when the truck was started. We discovered that if we turned the key ON, without starting the truck, that the TRAILER CONNECTED message came on the DIC. Then, the truck could be started and the brakes operational.Recently, we can no longer connect the brake system using the above method and I have no trailer brakes. When the key is turned ON, the HBA-CAM Actuator unit makes a click sound, but does not activate the brake system.

Was the electric over hydraulic system on the trailer a Gen 5 or Gen 6 with the appropriate serial number?


Resolved my issue with the GMC factory installed trailer brake controller not recognizing electric over hydraulic brakes.



This fixed our problems with our 2013 dodge and horse trailer. Acuator was trying to run all the time before we installed it

Patrick B.


Glad this was able to sort it all out. Thanks for sharing the info.


Very good quality and easy to install, a good solution for letting you use your factory brake controller on 2016 Chevy Colorado.



Been a year now, no glitches and is so transparent dont even think or worry about it


Very easy to install and get set up compared to other systems I’ve installed. The unit works very well and brakes nice and smooth. It is on a boat trailer and has been under water several times. No issues with it at all.

As a personal preference thing, the brakes take very slightly longer to start actuating compared to the other system I installed. At this point I’ve adjusted to the difference, but it bothered me at first. If I had not used the other system, I wouldn’t have noticed.


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


This is the missing link the secret to make your truck and trailer work together. I recently purchased a 2006 6 horse trailer with electric over hydraulic brakes. I pull with a 2017 Ram 3500 the day I picked it up from the dealership they went through all the typical check list. Everything worked except for the brakes so after 2 days of dealing with the trailer dealership telling me that there was nothing wrong with the trailer and that it was all my brand new truck I decided to do my own research and thats how I came across this necessary missing link. Wired in very easy install now the brakes work great.


I have a 2017 GMC Dually that has integrated trailer brakes so I added this to my 2011 DRV and it worked great, its been a year and I forgot I even had it. Set my integrated break controller to 9 and I don't have issues even going down passes. This is cheaper than a good external brake controller and no box at your knees.
