Everything Needed to Install Electric Over Hydraulic Disc Brakes on Trailer with 3,500 lb Axle

Expert Reply:

I can help you pick out the parts you would need and make it as simple as possible, but there isn't a single axle electric over hydraulic kit that includes everything. You would want to start the part # HS381-9067 which comes with the nicest actuator around, a breakaway kit, junction box and the needed wiring.

For the brake components you would want the part # K2R35D for a 3,500 lb kit unless the trailer will be seeing saltwater. In that case you would want the # K2R35S instead.

For a brake line kit you then would want the part # DM5424.

Not all brake controller are compatible with this style of trailer brakes so you will need to verify that you have a compatible brake controller like the part # 90885.
