Expert Answers about Hydrastar

  • Brake Controller Recommendation for a Truck with Air Brakes and a Trailer with Electric Brakes
  • The trailer brakes work on a separate circuit than the lights. You have a couple of options to control the electric brakes on the trailer. One option is to use an air over electric brake control, # 1300-80. This unit connects to the air brakes on the truck and when the brakes are applied it sends an electric signal back to the trailer brakes. The other option, and what I would do, is to use an electric brake controller like # 90885. For either of these controllers, the red wire attaches...

  • Converting Military Trailer Air Over Hydraulic Drum Brakes to Electric Over Hydraulic
  • You are correct, there are 4 electric over hydraulic braking systems, from 3 manufacturers, that can be used to eliminate the air over hydraulic actuator on your M200A1 trailer. These systems all require a breakaway system to meet DOT safety standards. I will detail each system for you so you can select the one that will work best for your truck and trailer setup. First, the Dexter Electric Over Hydraulic Brake Actuator, # K71-650, would be a good choice because it will work with the...

  • Troubleshooting Electric Over Hydraulic Braking System that Uses Hydrastar Actuator
  • A dead breakaway batter can cause an actuator to not work properly. The actuator draws power from the breakaway battery and the tow vehicle, but most of the amps will be drawn from the battery. The tow vehicle basically just provides a maintenance charge to the breakaway battery. Since it takes a while to get going and the voltage at the actuator is below 12 volts, I would guess either a bad ground or a dirty/corroded trailer connector. I would remove the ground connections and grind...

  • Wiring Diagrams for Hydrastar Electric Over Hydraulic Trailer Brake Actuators
  • If it is a 1000 psi then it would be the Hydrastar for drum brakes. The newest one is # HBA-10 and it has different wire colors, see picture. So you know that black is 12 volt power in and white is the ground. Blue/white goes to the break away switch. So that leaves red and green. One of those two has to be input to the Hydrastar from an in-cab brake controller. The other, I am not sure of the function since the wiring for HBA-10 only shows 4 wire connections. It might be similar...

  • Best Electric Over Hydraulic Brake Actuator for Trailer Disc Brakes
  • We prefer the Hydrastar Actuator part # HBA16 as it is the most reliable and works the best. This would be the best option for your trailer. We have the least amount of issues with this actuator and it is the one our installers like the most so we recommend it the highest. For a tandem axle brake line kit that uses rigid lines except for the lines that attach to the assemblies you would want the part # DM5425. Or if you wanted a kit that has the lines, a breakaway kit, and the actuator...

  • Electric Over Hydraulic Brake Compatibility with Ford, GM, and Dodge Integrated Brake Controllers
  • The adapter # HBA-CAM will only work with HydraStar Electric-Hydraulic Brake Actuators. The Dexter actuator does not work with the GM or Ford integrated controllers but the Dodge ones seem to be fine. For the 2011 GM truck you will need to install an aftermarket controller. We actually have an FAQ article that covers this very problem. I have included a link to it for you. For a compatible brake controller I recommend the P2, # 90885, because it is easy to set up and easy to use. There...

  • Comparing Drum Brakes to Disc Brakes of a 5th Wheel Trailer
  • I always recommend choosing disc brakes over drum brakes if you have the option. Disc brakes will provide more stopping power, less fade and require less maintenance because they have fewer moving parts. If your 5th wheel trailer currently has electric disc brakes and you want to convert to hydraulic disc brakes, then you will need not only the brakes, but a brake line kit and an electric-over-hydraulic actuator for disc brakes. You will also need a brake controller for your tow vehicle...

  • Can Vacuum Over Hydraulic Brakes be Converted to Electric Over Hydraulic Brakes
  • Since the braking power is still hydraulic, you should have no issues converting from a vacuum over hydraulic system to an electric over hydraulic system. The electric over hydraulic actuator will take the place of the vacuum that pressurized the existing brakes. If your trailer has disc brakes, the # HBA16 actuator that you referenced is a great choice. If your trailer has drum brakes, you will want the Hydrastar Electric Over Hydraulic Actuator for Drum Brakes # HBA-10. Often,...

  • Carlisle Hydrastar Electric Over Hydraulic Trailer Brake Actuator Runs But Does Not Build Pressure
  • The following are the troubleshooting tips from Carlisle: If the Brakes are slow to respond: Re-bleed the trailer brakes and atuator. If the trailer is equipped with drum brakes, re-adjust the drum brakes to the trailer manufacturer's recommended running clearance. Slow response can be caused by trailer wiring that is too small. Slow response can be caused by brake lines that are too restrictive on the trailer (small diameter/long length restrictive fittings/routing restriction) If...

  • How to Bleed Brakes on a Trailer with an Electric Over Hydraulic Actuator
  • The first step to bleed the brakes is to have the Carlisle HydraStar Electric-Hydraulic Actuator # HBA16 activate so that hydraulic pressure is being made in your brake system. You can do this by having somebody step on your tow vehicle brakes while your trailer is connected. They will need to be pressing the brakes while you are performing the following steps Starting with the brake furthest from the actuator open the bleeder screw and allow it to remain open until seeing brake fluid...

  • Carlisle HBA-10 Electric Over Hydraulic Brake Actuator Not Working with Dodge Factory Brake Control
  • Your Hydrastar actuator is not cycling on to build pressure to apply the brakes when needed. This could mean that there is an electrical problem or a malfunction with the motor, or even a problem with the brake controller. I have included a picture of how the unit should be wired up. Any corrosion could be a cause of the problem. Make sure that the trailer and vehicle connectors are clean and free of corrosion on the pins and around back where the wires attach. You can also make sure...

  • Installing a Brake Controller on a Freightliner M2-106 with Air Brakes
  • Trucks with air brakes might not have wire at the brake switch for a brake controller but I do recommend checking that first. The brake switch should be located above the brake pedal with wires going in and out of it. Use a circuit tester such as # 3808 to test the wires (the truck may have to be on, but not running). You need a wire that only shows power when the brake pedal is pressed and not when the headlights or turn signals are on. If you cannot locate a wire at the brake switch...

  • Installing Brake Controller On Kia Sorento For Towing Enclosed Trailer
  • In order to use a surge coupler, you'd need to replace the coupler on your trailer, as well as the brake assemblies and possibly the brake drums. You'd also need to run brake lines. Honestly, your most economical and safe way to proceed here would be to complete the wiring on your trailer, and install a 7-way and a brake controller. Installing the brake controller would be a pretty simple process. I'd recommend you go with a proportional brake controller, like the Tekonsha Primus, part...

  • Troubleshooting a HydraStar Electric Over Hydraulic Brake Actuator that Stopped Working
  • The first thing I would do is check the brake output circuit on the 7-way of your tow vehicle. You will want to use a circuit tester like our part # 3808 to check for voltage at this circuit when the manual override of your brake controller is activated. If no voltage is present there then you know the problem is on the tow vehicle side of the equation. Basically the brake controller or brake controller wiring is at fault and will need to be checked an fixed as necessary. If there is...

  • Installing a Trailer Brake Controller on a 2010 Chevy Silverado with Factory Tow Package
  • On a 2010 Chevy Silverado with a factory tow package, you will find the wiring from the brake controller under the dash, driver side, held together with white tape or a tag that explains the functions of the wires. There may be 4 or 5 wires but you only need 4 of them. If your brake controller has blunt cut wires coming out, you will need to connect them to the truck wiring using butt connectors. We offer a Wiring Installation kit that comes with several different connectors, electrical...

  • Plumbling Hydraulic Brake Lines for Tri Axle Boat Trailer
  • Although I don't have a diagram for a tri-axle trailer, I do have one for a tandem. If you refer to the photo, you would plumb the brake lines as shown, but would add the additional lines and tees for an extra axle. Here's the part numbers of the items shown in the photo. (A) 12-27/32" Long flexible hose ( # T0777300) (B) 18-25/32" Long flexible hoses ( # T0776500) (C)19' Long steel line ( # T4336000) (D) 66" Long steel lines ( # T1086600) (E) 30" Long steel line...

  • Is GM OEM Brake Controller Compatible with HydraStar Electric over Hydraulic Brake Actuator # HBA16
  • Even though our experience tells us that aftermarket controllers are typically more reliable than the OE controllers, if the factory brake controller on your 2007+ GM truck is functional it is not necessary to disable it in order to use a generation 6 or newer HydraStar Electric/Hydraulic trailer brake actuator like the # HBA16 you mentioned. You would simply need to use the Control Adapter Module, part # HBA-CAM. The adapter module will allow your factory controller to work with the Carlisle...

  • Solution for Using 2012 Ram 4500 with Factory Brake Controller on Both EOH and Electric Drum Brakes
  • Some of the Dodge factory ITBMs (Integrated Trailer Brake Module) are not to be used with electric over hydraulic trailer brake systems; they are to be used with electric trailer brakes only. The linked article covers this circumstance in some further detail. In some cases the slow response time could be caused by a need to re-bleed both the trailer brakes and the actuator. If trailer wiring is too small in gauge this too can cause a response delay; the same applies to the brake lines...

  • Electric Over Hydraulic Brake Actuator For A 20000 Lb Trailer With Disc Brakes
  • You mentioned a 20 ton (40000 lbs) tag trailer with disc brakes. If you have a 20 ton trailer it would most likely come with air brakes. Next, you mention a tandem axle trailer with two 10000 lb axles and disc brakes, so I am thinking you were meaning the same 20000 lb trailer. For your 20000 pound trailer with disc brakes, I recommend the Titan BrakeRite EHB Electric-Hydraulic Actuator for Disc Brakes, part # T4813100. If the distance between the front axle to the trailer hitch is 16...

  • Converting Military M105A2 Trailer From Air Over Hydraulic Brakes to Electric Over Hydraulic Brakes
  • You should just need an electric over hydraulic actuator such as # HBA-10 for drum brakes or # HBA16 for disc brakes. You should not need any additional brake lines or anything because the actuators work with the hydraulic lines and brakes that are already on the trailer. The tow vehicle will need to have a brake controller that is compatible with electric over hydraulic brakes, such as the P2, # 90885, and both the vehicle and the trailer will need to be equipped with matching trailer...
