I know there is new school of thought beginning to favor electric brakes on boat trailers. (Hydraulics are too expensive for me at any rate). Seemed that it even went so far that Fulton made marine brakes, thought not guaranteed for saltwater. Below is a text clip I got from e-article on them:

"Electric trailer brakes have been used successfully in the recreational vehicle and horse trailer industries for many years, " says Fulton's Craig Wilson. "The main concern with using electric brakes on boat trailers was corrosion or shorting out of electrical components when submerged in the water. The electrical connections we use are resin-encased and sealed against moisture. The result is a brake that is reliable in water."


Do they still make these brakes? I have googled and cannot find a thing on them.

Another option would be to use the ordinary electric and seal it as best I can- whatever that may mean. Anyone done their own version of "water-proofing" of electric brakes, and did OK in saltwater?

Thanks

We use to sell them they retailed for about $100.00 each for the 10" size. Electric brakes can be used on boat trailers, but in the end you still have a drum brake system and corrosion can be a major problem. The other issue is having to tow with a vehicle that has an electric brake controller installed. We have customers that use the standard Dexter electric brakes, but mostly in fresh water applications. For most small boat trailers a surge disc brake system is the best option.

I have never understood why some people are so against brake controllers. To me it is a far better system of controlling the brakes, i can adjust them or manually apply them from the drivers seat. Its not like a controller is expensive, the $50 one work fine; $100 will buy a nice one.

Will the electrical connections cause problems any faster than any of the other common problems you see with surge brakes in salt water?

My question therefore would be, with one or two monthly dips going in and out of saltwater; what parts of the brake assembly would be most affected by the saltwater.

I would presume marine grease would be used for the bearings, silicon sealant on electrical connections... just as one does for the trailer lighting. Don't know what you could coat the springs and magnet with that would not contaminate the shoes and drum wall... hmmm.

I don't think I said anything about being against electric brake controllers, it's just not all tow vehicles have them installed. In the end electric brakes are drum brakes, and just like a surge drum brakes are more susceptible to corrosion. The flush kits for them are a joke, IMHO if you are in salt or brackish water a disc brake system is the way to go. Again in my opinion an electric over hydraulic disc brake system is the best available, but for smaller trailers it can be an overkill.

Psiena,

If you don't have any brakes on the trailer now and no controller in the tow vehcile, the price for each system is going to be close to the same. Being that you are planning on using this in salt water, it would probably be best to stay away from any drum brake system (surge or electric).

Well I do have a controller installed. I guess you are thinking of a surge actuator and disc brakes. In the 3500lb range you can get to around $375- $400 in parts costs, single axle, 10 in., if I read you right. I would be at $150 for the electric since I have the controller in with the 7 pole receptacle. . May be worth considering if the corrosion affect is just too much. Just wish the electric/hydraulic actuators were not so darn expensive... $590+... Just insane...

If you already have the controller installed it is still going to cost around $225.00+ for the drums, backing plates, and the break-away kit.

I think you do not need a break away device for anything under 3500lbs, correct?

I was looking to see if anyone did use the electic drum and found a good method to maintain and replace them as needed that they were happy with. I have read some things which gave me good ideas, but I just do not know what the rate of corrosion would be like between my time to get the maintenance done.
