QUESTION ABOUT CSA VIOLATION

You have several misconceptions

Everything on the truck is part of the pretrip. Everything!.
You have no CSA points. The company gets 2 for that specific violation. You have a PSP, which simply lists violations with no points.
Also, everything on the truck is part of the pretrip. I can't emphasize this enough. Everything.

If safety doesn't care, just move on with life. It's not worth worrying about.

 

That jam nut is supposed to be tight against the fitting at the end of the rod, which connects the rod to the slack adjuster. Without it being tight, there is a slight possibility...especially with new hardware...that the rod could spin, affecting the ability of the slack adjuster to maintain proper adjustment or worst case the fitting on the end gets backed all of the way off and you have NO functional brake on that wheel.

Yes, it is part of the pre-trip.

 

While you are checking the jam nut on the clevis during your pre trip also check the clevis attachment and cotter pin. Be safe out there

 

Yup. I've found them missing before, too.

 

Doesn’t matter, it wasn’t where it was supposed to be.

 

Learning something new is always a good thing. I knew exactly what it was and thought it was a pre trip item but then again I am a inspection mechanic so my pre trips are probably a lil overboard lol.
