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


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?


Expert Reply:

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.
