Troubleshooting Trailer Brakes Being Locked Up With 7-Way Disconnected From Tow Vehicle

Question

Question:

My brakes on my 2010 keystone passport travel trailer keep locking up even when Im not plugged in. I cut the wire for trailer brakes on the axle and it released it. The main 7 way plug got damaged so I rewired it and after that is when my trailer brakes locked up. But I connected them the right way.

It sounds like you have an issue with your Breakaway Kit # 20099. This is where the power is coming from to lock your trailer brakes when it is not connected to your vehicle 7-way. You will want to check to ensure the disconnect is fully seated and the wiring for it is not damaged. We do have a Replacement Switch # FA80-00-2040 if your switch is allowing power to flow through the switch with the plug in place.

The attachment bolts for a 5-bolt brake assembly like the part #AKEBRK-6R should be torqued to 30-50 foot/lbs. If you don't have a torque wrench handy, if you tighten the bolts until the lock washers flatten out, you'll be pretty darn close…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
