Air brake issue

You have me on thank one! I would guess the trailer first.

 

or is it the blue one first?!

 

That is an interesting question! I do not know. Most folks reading this never even saw a three valve set up or a wingwham.
I will just have to hope I answered enough of the other questions correctly to pass.
What are the correct answers to these questions?

 

yes its the yellow. good job @x1Heavy

 

what about the gap between your chest and seat belt. how many fingers

 

That is beyond my memory. However the blue is the trailer air supply on the three button set up. It was a older brake system that had no meaning in today's modern trucks being separated when they stopped making that three button set up.

I enjoyed those rigs, not too much trouble other than a occasional brake pad dragging when one of the buttons wont come out right.

 

nope. the yellow goes first. it mite appear both but the yellow goes first

 

Oh you are killing me now. Never even heard of that. I have to have some relief with some of these new vehicles pinning me to the seat. Some Freightliners have an adjustable clip on the shoulder belt. A large metal spring clip for the office will work as well. My personnel truck did not come with a shoulder belt just the lap belt. I will just say that is not required for me.
I give: Uncle! How many fingers?

 

3 fingers. anymore then that. the dot can write you
