What Will Allow Factory Brake Controller of 2013 Chevy Silverado to Operate Hydrastar Actuator

Question

Question:

I have a 2013 Silverado 3500 and an Elite trailer with eoh brakes. I put a HBA-10 HydraStar Electric Over Hydraulic Actuator for Drum Brakes - 1,000 psi on the trailer thinking that was why the brakes wouldnt work. Then I found out the factory installed trailer control wouldnt work with eoh brakes. My question- will the HBA-CAM make the brakes work? Thx

Yes the adapter part # HBA-CAM will allow the factory brake controller of your 2013 Chevy Silverado 3500 to activate your Hydrastar actuator part # HBA-10. That's all you'd need and you'd be set.

Hi David; this is pretty common and all you really need is to throw in some simple diodes #RM-690. These will only allow power to flow in one direction so it will stop any backfeeding and power drain. It sounds like everything is in-line so you can…

Answer 9

Yes you need the diode arrow to point towards the brake controller. That will allow the voltage to travel into the controller but not backfeed back on to the Highlander in any way. If you need a diode we have the part #RM-690.
