Question:
Looking to convert my tandem axle trailer from drum to disk. 6000 lbs axles with 6x5.5 15 wheels. All use is salt water. Probably use DE28YR or KOD69FR hub/rotor brake kits. Wondering about electric acuator that can be mounted on trailer for this application? Saw one on ramp that was mounted on winch tower, looked like a good location. dont see anything similar. what would you recommend?

Expert Reply:
Hey Paul, for an electric over hydraulic actuator for a boat trailer actuator I would recommend the Hydrastar Marine Actuator # HS481-8067 which was setup for boat setups like yours. This will perform the best as well as was designed for the wetter application of being on a boat trailer due to its venting. Mounting on a winch tower would be a solid idea although we don't have a recommended way to accomplish that.
You will need a brake line kit like the part # HS496-252 to go along with everything as well.
