Before I go buy a new one,I'll give this one try. Trouble is,I don't know electronics from a bale of hay and I don't have enough info for anybody to go on.
I don't know the brand,so that's probably the end of it,but there's a controller in my 85 Ford F250 that was in the truck when I bought it in 90. It has a wet line from the master cylinder to activate it. It had a short lever on it too,has a red light that comes on when it's activated. There's a knob on the underside that I always thought adjusted the sensitivity from the pedal,but now I don't know. Is there a possibility that a controller that old would change the amount of current that goes to the trailer with that knob? I don't know,amperage,ohms,whatever?
The last few times I used the trailer the brakes were getting worse. Monday they didn't work at all as far as being able to feel them even start to drag on the trailer when I activated them with the lever. I tried to adjust them and all the adjusters were froze up. I took a hub off to free one up and the face fell off the shoe. Went to town,ordered new ones,changed them on all 4 wheels,freed up all the adjusters. I got them all put in. I can hear them click inside the drums,I ALMOST can't turn the wheels by hand when somebody activates the controller,but if I really horse on the wheels,I can turn them.
Still,no drag,won't even slide a single wheel in the dirt. I've been under that thing at least six times tightening the adjusters. If I hold the lever for a quarter mile or so,the drums get hot,but no stop.
I've turned that knob until evidently I've turned it all the way off inside somehow,because it just keeps going one way but won't turn the other way now.
So is it possible that a controller that old is sensitive to current and just needs to be replaced or is the problem in the brakes on the trailer?
