Expert Answers about Hydrastar

  • Compatibility of Trailer Brake Controller with HydraStar EOH Brake Actuator
  • To have the brakes in your 2016 Ford F-350 Super Duty activate your trailer's electric-over-hydraulic (EOH) brakes your in-cab brake controller must have an operational setting specifically for EOH systems. The better aftermarket brake controllers such as the Prodigy series from Tekonsha, the P2 # 90885 and the P3 # 90195, include the EOH option in their main menu screens. This type of actuator, such as the Hydra Star # HBA16, requires an EOH-compatible brake controller since the electrical...

  • Adding Electric Over Hydraulic Brakes to a 3-Axle Boat Trailer
  • To switch your boat trailer from hydraulic drum brakes to electric over hydraulic disc brakes there are a few parts you will need. You will need the EOH actuator itself. What I recommend is the Hydrastar Marine Electric Over Hydraulic Actuator with Breakaway and 7-Way RV Harness # HS381-9067. You will not have to replace the brake lines or the coupler. If you can lock out the coupler (keep it from actuating in and out) that would be ideal. You will also need to have a brake controller...

  • 2017 Dodge Ram OEM Brake Controller Not Working with Carlisle HydraStar EOH Actuator
  • Carlisle HydraStar says that their EOH actuators, like part # HBA16, are compatible with the OEM brake controllers from Dodge. The problem that we have been seeing though is that even though OEM brake controllers are convenient, they tend to go bad or not work as well as promised. There is a module # HBA-CAM but it is only supposed to be used with some Ford and Chevy models. What I recommend doing is getting a new brake controller that we know for sure is built to work with EOH systems...

  • Brake Controller Compatibility with EOH Trailer Brake Actuators
  • Some trailer brake controllers, including many factory-installed models, will not work with an electric-over-hydraulic type trailer brake actuator like the Hydrastar # HBA16. EOH actuators like this present a very different electrical load to the brake circuit than a typical electric drum brake and some brake controllers simply won't work. Others can be made to work with an electrical adapter like # HBA-CAM. You will want to confirm that the controller you are using has an EOH setting...

  • Recommendation for Towing Trailer with Electric Over Hydraulic Brakes with Four Chevy Silverados
  • As you mentioned, the integrated brake controllers on your Silverado 3500 trucks will typically not work with electric over hydraulic trailer brakes. The Chevy/GMC factory controllers are simply not compatible with electric over hydraulic brakes and essentially will not even recognize that a trailer connected when equipped with this system. Other than converting to all electric brakes on the trailer, there is nothing you can install or add to the trailer itself to resolve this issue. If...

  • Everything Needed to Install Electric Over Hydraulic Disc Brakes on Trailer with 3,500 lb Axle
  • I can help you pick out the parts you would need and make it as simple as possible, but there isn't a single axle electric over hydraulic kit that includes everything. You would want to start the part # HS381-9067 which comes with the nicest actuator around, a breakaway kit, junction box and the needed wiring. For the brake components you would want the part # K2R35D for a 3,500 lb kit unless the trailer will be seeing saltwater. In that case you would want the # K2R35S instead. For...

  • Recommendations for 2018 GMC Sierra 3500 5th Wheel Setup
  • The GMC integrated brake controller on your 2018 GMC Sierra 3500 may or may not work with your EOH system. Previous model years have required an adapter like the HydraStar # HBA-CAM to function well together. The Pull-Rite Auto slide hitch will work in a standard bed of the GMC truck. You don't need a sliding hitch with an 8 foot bed, but you would with the 6-1/2 foot bed. For either bed size, I recommend the custom bed rails # RP50066-58 for industry standard above bed rails. ...

  • Prodigy Brake Controller for Use with Electric-Over-Hydraulic Brakes
  • A brake controller that is to be used with electric-over-hydraulic (EOH) brakes needs to have a setting for that type of operation. On a controller with this capability, like the Prodigy P3 # 90195, the OEH setting can be selected from the menu screen. Some factory controllers may not have the option for OEH operation so you'll want to check the instructions for your controller to see if/how it can be set for that operation. If it cannot work with EOH actuators then you'll want to choose...

  • Recommended Actuator and Wiring for Boat Trailer Upgrade From Surge Brakes
  • To add EOH to a surge brake trailer, you will need to add the electric components to make the actuator function. You can get the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 and then wire your actuator into that junction box. You will be able to simply connect to your current hydraulic brake lines. For your actuator, I recommend the HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HS381-8067 or the HydraStar Vented...

  • Does the Factory Brake Controller in a Ram 3500 Need An Adapter to Work with EOH Brakes
  • I called HydraStar who is a prominent manufacturer of electric over hydraulic brake actuators and they said the issue that you are having is caused by a compatibility error between the factory integrated brake controller and your electric over hydraulic brake actuator. Therefore, you will need to use an adapter. Please also make sure that you are in the electric over hydraulic mode if that is an option. In order to recommend the correct adapter I will need to know what electric over hydraulic...

  • Brakes on My 5th Wheel Are Not Working But Trailer Lights All Work Fine When Connected
  • If you have electric brakes or electric over hydraulic brakes, the first thing to do in either case is take a circuit tester like # PTW2993 to test your signal from the brake controller to the trailer connector at the rear of your 2015 Ram or the bed if you have the relocation attachment like # 41157. With the alligator end of the tester clipped to a clean ground, touch the probe to the 5 o'clock position while hitting the manual override on your brake controller. You can also use a 7-way...

  • Using HydraStar HydraStar Electric Over Hydraulic Actuator HBA-16 During Prolonged Stops
  • This was a very intelligent question and you are correct that the HydraStar Electric Over Hydraulic Actuator for Disc Brakes # HBA16 can be overheated during longer periods of stopping. To get the definitive word I contacted HydraStar about your suggestion in regards to adjusting the gain to zero on your brake controller during stop and go traffic and was told that setting the gain to zero would "alleviate the potential for overheating in stop and go traffic." I was also told that...

  • Parts Needed to Change a Triple Axle Kaufman Trailer from Electric to Electric Over Hydraulic Brakes
  • To change your electric brakes on your Kaufman trailer to an electric over hydraulic (EOH) system you will need to hydraulic brakes, brake lines, an EOH actuator, a breakaway kit (which you should already have), and a brake controller (which you should already have). I highly recommend going with the HydraStar EOH Actuator # HBA-12 which is one of the best options out there and has received great reviews from other customers.

  • U-bolt Spacing and Frame Size for the HydraStar Clamp-On EOH Mounting Bracket # HS304-7169
  • I was able to go out to the warehouse and measure the clamp-on mounting bracket for HydraStar EOH Actuators # HS304-7169. I made you a dimensional diagram to better see, but found that the mounting holes for the u-bolt are 13-1/8 inches by 3-5/8 inches center on center, and the interior dimensions are 12-1/2 inches by 2-15/16 inches. So this will fit frames up to 2-15/16 inch frames if using 5/8 inch thick ubolts. I have linked the HydraStar Clamp-On Mounting Bracket to this page for...

  • HydraStar Actuator Breakaway Kit Option
  • If you wanted to order the HydraStar # HBA16 with a breakaway kit you would instead want the part # HS381-9067 which also comes with wiring and a junction box. Otherwise the breakaway battery part # 34-285 would work well as it has more than the needed amp rating.

  • Does the HydraStar Electric Over Hydraulic Actuator Part # HBA16 Need a Separate Battery
  • The HydraStar Electric Over Hydraulic Actuator part # HBA16 will receive power from the breakways switches battery. The 12 volt power circuit on the 7-way trailer connector will then be used to charge the breakaway switches battery. I have attached a photo of the electrical schematics of the actuator for you. The HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness part # HS381-9067 comes with a breakaway switch and battery but if you already have a 7-way...

  • Availability of HydraStar Disc Brake Kit for Drum Brakes
  • There is a drum brake version of the part # HS381-9067 that you referenced. For that you would want the part # HS381-9066. The big difference between these kits is the pressure rating. Disc brakes require a higher psi at 1,600 psi whereas the part # HS381-9066 is lower at 1,200 psi.

  • Adapter for Allowing Ford Integrated Brake Controller to Recognize Electric Over Hydraulic Actuator
  • Most newer truck manufacturers have made their integrated brake controllers compatible with electric over hydraulic actuators like the Hydrastar # HBA16 that you mentioned but we have found that it's not always consistent that they will work without issue. Best solution we have for you would be to use the adapter part # HBA-CAM which is designed for integrated Ford brake controllers like you have. Once installed your truck will recognize that a trailer is connected.

  • Brake Fluid Capacity of HydraStar Electric Over Hydraulic Actuator for Disc Brakes
  • I reached out to the manufacturer who told me the HydraStar Electric Over Hydraulic Actuator for Disc Brakes # HBA16 has a fluid capacity of 10 oz. They told me that was going to be more than ample capacity to allow for brake pad wear once the brakes are bled and the unit is topped off. I have added links to video reviews of this actuator for you to take a look at.
