Installing Electric Over Hydraulic Disc Brakes on a Trailer with 3,500 Lb Axles

Question

Question:

I am hoping to buy HS381-9067, T4830000 and T2HRCM10DAC. Will this do the complete job of changing the electric drum brakes to EOH disc brakes on my 5th wheel trailer? I have a 2013 F250 with factory installed brake controller. Will there need to be other parts purchased to complete the job?

The HydraStar Marine Electric Over Hydraulic Actuator part # HS381-9067, Titan Hydraulic Brake Lines and Fittings for Tandem-Axle part # T4830000, and the Titan Premier Disc Brake Kit part # T2HRCM10DAC will give you almost everything you would need to add electric over hydraulic disc brakes to your trailer.

Since you have the factory integrated brake controller on your 2013 Ford F-250 you will also need to use the HydraStar Electric Over Hydraulic Actuator Adapter Module for Ford and Chevy Brake Controllers part # HBA-CAM. I have attached our adding disc brakes to a trailer help article for you as well.

Your 2014 F-250 may or may not require an adapter. HydraStar states only the (2007 - 2008) Ford F-250 requires it however, in some late model trucks it can be hit or miss. If the factory brake controller isn't putting out enough voltage then it…

The electric over hydraulic actuators can be touchy. The factory integrated brake controllers often have issues with consistency with EOH systems. My recommendation is to replace the factory brake controller with the Redarc Tow-Pro Elite Trailer…
