Well, I seem to have rejoined the land of the gainfully employed, or I soon will anyway (start new job on the 15th). That means it's time to do some maintenance on my trailer I've been putting off for quite a while (like since I last put the boat in and the ongoing PITA with the hitch during the launch). I'd like to get the boat out of the water this year to do some projects over the winter and at a minimum the actuator has to go, the current one is beyond repair I believe.

I've currently got drum brakes, and with the actuator messed up as it is, I'd guess that they may be in a bad way as well, so I'm thinking of switching to disc brakes & a new actuator. I know several folks have done this, and I'm wondering how much of a pain it'd be to do myself?

Can I use a disc actuator on drum brakes? It seems like it's just hydraulics so if you push fluid into the lines, the brakes should engage, but maybe I'm missing something? They sell both drum & disc actuators and I can't really find the difference between them. Does anyone know what it is?

I replaced the surge brake system with electric brakes on my 2002 trailrite, pulling WK 250....the electric brakes on the trailer actually can stop both the trailer and the truck using the the trailer brakes only...it is adjustale brake system...the system is adjustable 50% truck 50% trailer, 60% trailer 40% truck etc ....maybe you know someone with electric truck and a travel trailer system you could try.

I replaced the axels on my Catalina trailer with 5200 pound rated ones. The 3500 pound ones were bowed and one broke from rust on the inside. All four wheels have electric brakes. I did not have this information at the time, but I understand that Dexter makes electric brakes especially for boat trailers. I did drill drain holes in the new axels and also filled the inside with paint. I have another trailer with surge brakes and they have given me trouble almost every year keeping them working. I will switch them to electric as thy are currently not working correctly. I think that the disc brakes on a boat trailer may be problematic because of tighter tolerance and possible corrosion on the cylinders and pucks causing them to stick due to Lack of regular use, as on an automobile. I could be wrong about that.

A disc brake actuator is different from a drum brake actuator. A disc brake brake actuator has a large hole in the fitting at the back of the actuator and doesn't have a check valve. You can't use a disc actuator on a drum brake system. You also need a wire from your backup light circuit to a solenoid valve at the back of the actuator to prevent the disc brakes from operating when you are trying to back up. If you're going with disc brakes you need to purchase the whole disc brake system components.

I went electric from this source as well, Much safer than surge.

Is it OK to put electric brakes into salt water?

As far as I know electric brakes are only available as drum brakes. Drum brakes have the disadvantage that you can't see what's happening inside the drum which in salt water is always something bad. You can get disc brakes with an electric over hydraulic actuator but this option is very expensive. I would go with disc brakes and a surge actuator made for disc brakes. They are pretty reliable and with disc brakes you can see what your brakes look like and you can hose them off to remove the salt water.
