Is Galvanized Coating Best for Salt Water Application for Boat Trailer Brakes

Question:

Hello, Im looking to replace the drum brakes on my boat trailer, used primarily in salt water, so Im looking for the very best corrosion resistance. I have a tandem axle trailer with twin 3,500 lb axles and 10 inch Titan drum brakes. The backing plates are very corroded. Im curious about the galvanized backing plates on these Demco brake sets, and the zinc-plated cylinder. Is there anything better for corrosion resistance? What is your recommendation? My trailer is hot-dipped galvanized and in great shape, so Id like to put the best brakes on it that I can find to last a long time in a salt water environment. Thank you!

The Galvanized Demco Hydraulic Brake Kit # 40716-15 is definitely the best coating that you can get for corrosion resistance. The other coatings are basically just different levels of powder coats while galvanized resists salt water much better. I do recommend rinsing your boat trailer off as well to help extend the life of the various components.
