Here's the deal...When coming to a stop, or slowdown, the trailer brakes lock up for an instant...then releases.

I know The brake controller is adjusted correctly as it just recnetly started to do this, but damn...it's got to be hard on the hitch...

any ideas as to why this hapens and what the remedy is would be appreciated.

Pull the drum that you know to be having this problem. The one you can see locking up. I bet you have grease on the brakes.

Or...

It could be a controller issue. What brake controller are you using?

I had the same thing happen on my boat trailer. Inside the trailer 7 way plug the trailer brake wire was loose. It had moved over and was touching the 12 volt brake wire. Every time I hit the brakes a full 12 volts went to the trailer brakes.

 

[FYRMAN]

Very rare that you see that problem. The brake wire has to move around two others to get to the 12v wire. You should have had clues before that happened. Brake lock up with your right turn signal on, or brakes locked in reverse.

try checking the brake light switch for brake lights. The fuse is a braker and it sounds like the adj. is set to high and tripping the breaker.

The fuse is not a breaker, it's a fuse. If it was a breaker, and it was tripping, there wouldn't be brakes at all. It wouldn't lock up the wheels.



If you spent half your time reading, instead of solving everyone else's problems, you might learn something.

Fyrman if you knew something that you were posting It would make me happy, But as I have said gefore I want no fight with you. Brakes are powered with a maxi breaker on 2000 F trucks It workes the abs syestem which poowers the break lights. If it trippes the breaker you still have breakes on the truck but no lights. no lights no trailer breakes. breakers come back on after they cool. If the tailer break controller is set to hard. it tripps the 30 anp breaker and wala they release because no power from break light. cool breakes again lock up and breakes breaker again. DU.

Give us a little more information. Does it do this every time you apply the brakes? If you brake, let off for a few seconds, and them apply the brakes again, do they lock again? Is your controller adjustable? If so, if you adjust it lower, does it make it any better or do they still lock up for when you first hit the brakes?

FYRMAN, we'll have to study that theory in depth since all the brake lights do is trigger the trailer brake circuit and the trailer brake system draws no juice from the brake light circuit, but what do we know? /ubbthreads/images/graemlins/biggrin.gif

If the brake controller does not draw any juice from the brake light circuit then why have it hooked up? It does draw to activate the controller and it emits a signal to turn on the brake lights.when it powers the brake lights it heats up the breaker and ittrips the breaker. And beleave me I am not trying to T any one off. But his problem is a short somewere.

I have one more question for you. When you first hit the brakes and it locks up, then does it release in a second or so or does it stay locked up until you take your foot off the pedal?
