Brake problems
Picked up rig to clean up for an upcoming trip. Brakes were almost non-existent on trailer set on 9 (normally run at 6.5 or 7). After 10 minutes or so with a few stops, they were up to maybe 15-20% of what they should be. If I took my foot off the brake at a stop light and held the controller all the way down, I would creep forward about 2-3 feet and then brakes would grab ahold. Kind of strange.
I was assuming I would have to take it in to dealer. So I hooked up pigtail and unhooked it about 4 times. Then to test, pulled the safety thing and tried to move forward. Wouldn't budge! Hooked everything back and brakes worked perfectly!!
From what I read on another thread, they mentioned wiring not quite crimped properly or with corrosion. So I am thinking maybe it is a bit of corrosion in the pigtail??? Comments anyone?
Thanks.

Your drums may have had rust on them, both on the brake surfaces and the surfaces that the magnet contacts. It may have taken a while to break through the rust to get good braking action.

And the trailer wheels need to rotate for the brakes to engage! but 2-3 feet is too much. I agree it's probably rust.

And it may have been film corrosion on the pigtail connector...this why some put dielectric grease in the plug. John

If you have greased the bearing by using the zerk in the center of the wheel, you may have over greased and blown the seal thus putting grease on the brakes OR if you had someone check and grease the bearings they may have done this too. If they used a powered grease gun it's quite easy to do this. I'd take the wheels off and check to see if you have any grease on the the brake pads and etc.
I also agree with the previous two comments, that it could have been rust or corrosion on the brakes themselves or corrosion in the wiring harness. They do make some electrical grease you can put on or in the connections to keep corrosion from getting to the parts. If your unit has been setting for any amount of time and if it has been humid this could also be the cause of you problem.

I'd also check the wiring near the axels, I've had the wires come loose, then you only get partial breaking.
