Question:

I accidentally pulled out my breakaway sw while unhooking from my 5th wheel. I didnt discover this till 2 days later and then I reed it. My concern is if I damaged my brakes during this time even though the rv was stationary? Or how I can verify their ok? Thanks

I would start with reinserting the Breakaway Cable Plunger # FA80-01-2206. Your breakaway box uses power from your battery on the 2018 Keystone Montana 3791RD 5th Wheel. You will want to ensure the battery wasn't completely drained during this time. If dead be sure to recharge the battery. The brakes should unlock but it may require you to backup to unlock them.

If they are still locked and won't unlock you will have to find out if they are being held on by a faulty break away or by bad magnets that became damaged due to being held on for so long.

A Circuit Tester # PTW2991 can help you determine if there is still power going to the brakes. If there is no power going to the brakes and the brakes are still on I believe the brakes were damaged. I have included an article below that can walk you through testing your brake magnets to check for damage.

Let me know what you find and I can help you with the correct parts required to fix your issue if there is one.
