Question:

I plan to change my brake system on my boat trailer. Are the above parts coated against corrosion for salt water launching?

asked by: Warren V

Expert Reply:

Because electric brake assemblies like the etrailer.com self adjusting brake assembly part # AKEBRK-7L-SA are not typically used for boat trailers, the assemblies are not specially coated for saltwater corrosion resistance.

Boat trailers usually use hydraulic brakes, and would use a hydraulic brake assembly like part # 42029 and # 42028. These assemblies are galvanized for corrosion resistance.

To convert to hydraulic brakes, you would need a hydraulic coupler/actuator like part # 099-175-00. This coupler is a fit for 2 inch trailer balls. It does not have a reverse lock-out, and should be used with free-backing brake assemblies like the ones I mentioned above. It is designed to bolt onto 3 inch channel trailer tongues. You would also need a hydraulic brake line kit like part # 9504.

The above is recommended assuming that you have a single axle boat trailer with standard axles.
