I need a brake controller for my bobtail dump truck that has air brakes. I want a controller that is proportional to brake my tandem dual trailer with electric brakes. I have a regular controller in it now and it doesn’t work well. The only one I can find is a Hayes 100400c controller, but nobody has one in stock. Is there another similar unit I’m not finding in my search?
 
That was the only one I found last year for my moho, ended up going with an inertial one instead. My trailer is nowhere near a tandem dually though.
 
Yeah they are both the unit I listed. Etrailer, if you look at the delivery date. Says they will deliver next year!😜 All the other sellers say out of stock. I’m looking for an alternative.:grinpimp:

If you want to gamble, there's a shit load of them on ebay.

This is what I can find.

Our water truck has a kelsey, but it's from the 80s and kelsey seems to have merged with hayes since then.

Um, it says out of stock.:flipoff2:
 
Was gonna recommend the Warner 1300-80 controller as I had luck with installing it a few years back in a kenworth for hauling our 48' tri-axle enclosed.. buttt I see that it's unavailable and/or discontinued as well:emb: but if you can find a new old stock one or ebay one, I can recommend it.
 
I don't really understand why the prodigy wouldn't be the same at half price?

That’s what is in the truck now. It doesn’t work well with the air braked truck. I need something that works progressively with the air brakes being applied. So the trailer is working at the same rate as the truck brakes. Kinda hard to explain. But, the regular controllers don’t play well with air braked bobtails pulling a 14,000 lb backhoe on a 6,000 lb trailer.

I understand your statement but I dont think the remote setup would work any different.

Are you running the correct boost mode for a truck with higher weight than the trailer?

If you look at the controller I referenced. It applies the brakes to the trailer thru the air pressure going up to the brake cans. It’s tied right into the brake airlines.

I fully understand the difference, color me skeptical that just changing the brake signal to air pressure will have a marked difference.

In my mind the brake pressure signal is going to come on at a certain pedal pressure then gradually but minimally increase, that force won't be linear to the truck slowing down (in my mind) and the controller will still require a inertial sensor to actually measure brake performance.

Just my .02
 
Can’t help you on finding one, but we’ve got a kelsey in an old single axle K100 that works fairly well.
 
Throw air brakes on the trailer.

Air braked tags are stupid cheap. There's your donor axle source.

I know you work with heavy iron every day. I in no way was trying to insult your intelligence. I just know what I have doesn’t seem to play well with my old ass dump truck no matter where I adjust the settings. I’m just looking for an alternative to try.😁
