Ram OEM Brake Controller Issues With Hydrastar Electric Over Hydraulic Trailer Brakes

Question

Question:

Hi I have a 2022 ram 3500 with oem brake controller. I recently bought a new trailer and noticed the brakes weren’t working as much and the emergency brake wouldn’t work at all. One I got home noticed a leak on one side of the trailer tires and removed the hub and saw oil all over the brake pad and inside the drum. So I replaced the wheel seal. I started driving and noticed my brakes were working better. Once I stopped I tried checking my emergency brakes with my oem controller and they don’t work. When I pull the pin they lock up fine. My friend connected his truck to my trailer and it did the same it didn’t work. So I connect my truck to his trailer and everything worked. Do you think it has something to do with the trailer wires?

It sounds like you need the Hydrastar Electric Over Hydraulic Actuator Adapter Module # HBA-CAM for the OEM brake controller on your 2022 Ram 3500. This will ensure that your controller works properly with the Hydrastar Electric Over Hydraulic Actuator # HBA16 as often times factory controllers do not work correctly with electric over hydraulic brakes.

I am having the same issue but the part you recommended states it is for Ford and Chevy brake controllers?? Does it also work on the Dodge controller?

@Stacy Yes, the Adapter Module # HBA-CAM will also work on your Dodge factory controller.

@BudM thank you! And this will get my EOH brakes to work? They worked just fine with my old Dodge that had an aftermarket controller but when I got this one, I cannot get them to work.

@Stacy It may solve your problem but you may want to have your brake controller programming verified by a local dealer. Since these are tied into the ECU if there is an issue with the ECU programming that could be all it takes.

@Jose Is your OEM brake controller in your Ford F-550 set to Electric over Hydraulic?

@Jose You're welcome. Yeah we don't see many errors with factory brake controllers on the 2015 Ford trucks. You'll want to make sure whatever brake controller you're using has an Electric over Hydraulic setting. The OEM brake controller can be adjusted by the settings menu behind the steering wheel.

Our tow vehicle is a 2019 Ram 5500. I have installed the Hydrastar in our 2010 New Horizons fifth wheel with EOH disc brakes and about to connect wires. Problem: our trailer has FIVE wires that connected to the prior actuator, a Titan Brake Rite. The Hydrastar has FOUR wires. Can you tell me how to hook it up? Thanks for the help.

@LarryV The older Titan BrakeRite EHB uses five wires and the Hydrastar uses four because the Hydrastar combines the breakaway battery function differently. Here's how the wires matchup: Black (Hydrastar) ? 12V power White ? Ground Blue ? Brake controller output Yellow ? Connect to the cold side of the breakaway switch On the Titan BrakeRite EHB, the fifth wire (typically violet) was used for the breakaway battery connection. The Hydrastar does not use a separate wire for this function, so you won't have a direct one to one replacement for all five Titan wires.

Answer 1

Hey Greg, the DeeMaxx Hydraulic Brake Line #DE54JR that you referenced is the correct thread size for the master cylinder of the Demco Surge Brake Actuator w Drop and Electric Lockout #DM8104311. This would work and is 24 inches long so hopefully…

Answer 2

Hey Jesse, since you have a Dexter 12k axle you would need the Kodiak disc brake kit part #KD87FR for the brake components and then for an idler hub you'd need the part #8-214-8UC1 which the disc brake kit would slip over. Are there hydraulic…

Hey Marc, welcome back! We can definitely put together the parts you need for the disc brake kit you are looking for but we don't have anything that is a single part number like what you mentioned. So you'd need two of the part #DE68YR for…

Hey Stan yes the factory brake controller on your 2023 Ram 2500 is compatible with EOH actuators like the Hydrastar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness #HS381-9067. We have found in the past, however, that OEM…

Hey Henry, that's a great question but the answer is that it depends...it depends on if your axle is above the leaf spring or below it. If your axle is above the leaf spring it wouldn't affect the trailer height. If below it would raise it.…

Answer 6

Yes. If you change no other components, the hanger length increase should directly correspond to the lift of the trailer. So, if you use a tandem axle kit like the Tandem-Axle Trailer Hangers for 1-3/4" Wide Double-Eye Springs - 3-1/4" Tall…

Hey Robert, thanks for getting in touch. You are definitely on the right track with the part numbers you mentioned. The #HBA16 actuator and #20TA-BLKIT brake line kit can be used. Instead of the #HBA16, you may want to get part #HS381-9067 instead.…

Hi Cw; sorry for the delay on this. If you can tell me what kind of spindle you have on those axles, or just tell me the bearing and grease seal part numbers, I can find the right disc brakes for the trailer.

Hi Rick; thanks for the question and the info you provided, and the answer is yes, you can absolutely convert from electric brakes to disc brakes. Disc brakes give you the best overall stopping power, so it's something I definitely recommend. For…

I might have a better solution for you. Unfortunately, #1289050300 Bulldog BX1 Gooseneck Coupler only is available in a 22 inch length. An option you might want to consider is replacing both the outer and inner gooseneck tubes. The Redline Gooseneck…

Hey Mike. The Deutsche Hydrapro Alpha G-1600 item #DH94FR and the DeeMaxx Alpha G1600 item #DE47SR have different fittings on them. The DeeMaxx actuator item #DE47SR has a brass fitting/valve that connects to the main brake line, whereas the Hydrapro…
