Use your Gen 6 or later Hydrastar electric-over-hydraulic brake actuator with your factory Ford (model years 2007 - 2008) or Chevy (model years 2007 - current) electric trailer brake controller by installing this adapter.


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.


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.

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.


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!

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 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.


Has work excellent since I’ve installed it very happy with service and the product

My brake system from etrailer has work flawless thanks for all your help in great parts

The actuator works great.

It is still working as it was intended.
Jon w - 11/08/2021


Worked perfectly on my 2015 GMC Sierra.


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

Jesse R - 09/03/2018


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.

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.

Works like a charm. We installed Tusons ABS break system on our trailer and we weren't quite able to get the performance that we hoping for until we installed this part. Although it is meant for Fords and Chevy, Tuson recommended it and it works great with our 2500 Ram 2018.


Never used it. Come to find out newer trucks don’t need it. But everything I have bought from etrailer has been great.


I received the HBA-CAM very quickly, however when I installed it, it didn't help with the GM Integrated Controller talking to the Hydrastar actuator. I called Cargo Towing, spoke to Wendall, who was very patient in talking me through numerous testing sequences. At the end of the testing, he sent another HBA-CAM without me having to return it to etrailer. His rationale is he stands behind his product and wants customers to be happy. I received the new HBA-CAM and had the same problem, spoke to Wendell again, had me create a test pigtail and completely bypass my trailer wiring and if the Hydrastar didn't work, he was going to send me a new one of these also. Bottom line was the Hydrastar did work with the test pigtail and my issue was a bad ground in the trailer wiring. Wendell stood by is products and more importantly, he went way above what is expected in today climate by providing suburb customer service. I will continue to use their products and purchasing through etrailer...two great customer service companies!!!


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

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.


It worked! We bought a new trailer but the electric over hydraulic brakes weren’t working. We installed the HydraStar Adapter and immediately had brakes. THANK YOU!


HBA-CAM solved my no brakes issue. Easy to install, still working great. I highly recommend it and ETRAILER.


This product did not work with Ram 2012 bulid in controller but I connected it with my P3 controller. It appears to be working but some it's not needed, others say it will help. Time with tell.

Not using it, it didnt help with the RAM2012 brake controller, had to go with after market controller.

Have put the Hydrastar Elect. over Hydr. on my last 2 boat trailers. This set up is better than anything else I have ever towed. Needed this part to make it work correctly with factory brake controllers on my truck.


Good to deal with


I had doubts on how u can just wire this up and get brakes. I had power to manual side on truck. Truck being a 16 2500 silverado duramax. Well wired this up took 10 min wire plug and play and it works great. I have brakes now and it is smooth also. Set mine bout 6 pulling a 4 horse elite 13'short wall living quarter loading down. I recommend any1 havn any brake issues get this. And etrailer is the best place to shop. Dont even waste time lookn round u cant find better prices or better people to talk to. I need a blaylock and a traileraid block ordering that today. Thank u etrailer.
