Brakes apply on their own

Make the time to complete repairs. Or you might have to have all the time to wrap up a fatality accident because your poor tractor trailer does not understand to leave the brakes alone in winter.

If you are a really good company, worthy of keeping good drivers YOU WILL make this load go away onto a different truck, preferably team while your driver baby sits this one at a good shop somewhere this week, hopefully not too long as necessary to solve this problem permanently so you can get back to trucking.

Or buy older legacy equipment and be done with all that computer crap slowly throttling the life out of your drivers ability to be productive and your company's ability to stay solvent. //tease...

 

I disagree with you often but this post is spot on... make the time before someone gets hurt or driver QUITS

 

Sounds like the treadle valve itself is faulty and leaking internally.

 

when you say it engages the brakes at 115+ psi system pressure, do you mean that they are engaged and the truck is undriveable?

 

Sometimes you just have to love technology.
