If you have new pads on the trailer, they will get pretty hot for a while. This is common; until they wear into a pattern.

When you get to the water, its NOT good to back right into the lake with hot brakes. Its better to let them cool off a bit. You risk cracking a pad, caliper, or rotor with the extreme temperature change. If anything, back into the lake VERY slowly, and let the water gradually make its way up the brake, rather than a quick dunking.

The 5th (blue) wire on your light connector is not for an Electric Brake Controller. The 5th Blue wire needs to get engaged when you shift the truck into reverse. If you have a modern truck, your 7 pin round connector has a pin for this. You will probably need to get a 7 pin round to 5 pin flat connector. I think even Wal-Mart sells them, but Boaters World, and any trailer hitch/camper place will have them. This blue wire, when energized by your backup light circuit on the truck, engages a solenoid that stops your trailer brakes from working when reversing. Surge brakes on drum brakes do not work in reverse. Surge brakes on disc brakes do work in reverse, hence the need for the solenoid to block brake pressure so you can reverse when you need to.
