Does Actuator have to be Removed when Switching Trailer from Hydraulic to Electric Brakes  

Question:

I have a bolt on Atwood surge brake actuator and if I convert the hydraulic drum breaks to electric breaks will I need to change the tongue and is there anything else I would need besides the AKEBRK-35 R and 35L. My suburban already has a controller and 7 blade and I have spools of wire to upgrade the trailer. Thanks again for your help

You do not have to replace the actuator on your boat trailer if you will be installing electric brakes. The actuator will still move in and out but that should not cause you any problems. Depending on the hub and drum assemblies you have now they may be compatible with electric brakes and they might not be. Check the various bits of information stamped into the hub and that may reveal if they are hydraulic only.

If they are hydraulic only then you would also need to replace the hub and drum assemblies. For that I would need to know the inner and outer bearing numbers stamped into the metal of the bearings as well as the wheel size and bolt pattern.

Since you have a 7-Way on the tow vehicle I recommend adding a 7-Way to the trailer, # PK12706, if it doesn't have one already. Make sure that the wire you have is heavy enough for electric brakes. Usually 10 gauge # 10-1-1 or 12 gauge, # 12-1-1, is used.
