2017 freightliner cascadia

If it’s a new design cascadia it’s directly next to parking brake knobs.
If the older one, it’s to the right of them.
I’m talking about the handle.

 

Their it is

 

It should be a handle labeled trailer brake , maybe the lettering has been rubbed off, but it's the black lever like in the picture above

 

I think some order trucks without the trailer brake handle. Why? Not sure. Guy I knew had a older FLD it didn't have one. I have seen others without also. Personally I would not be without one.

 

Why have something that's never used?

Keep your drums and brakes in good shape. Learn how to use brakes on ice. Won't have a problem.

I've only had 2 almost Jackknifes in almost 20 years. Never touched it.

 

I use it maybe twice a month. After I hook up.

 

I hook up and tug before connecting lights and air.

 

I have only ever needed it once in 10 years and that's because something snagged a brake line on a old semi I had and the brakes didn't work right apparently on the old truck coming up to a 90 degree turn and I grabbed the trailer brake to slow me down for the turn
