When parking a trailer without spring brakes, it is very important for safety that you use wheel chocks. Why?
|
The air could leak out of the trailer air tank, releasing its emergency brakes.
|
|
|
You may not notice a major leak in the service line until you try to put the brakes on.
|
|
|
if you don't use wheel chocks, supply air will be sent to the service line instead of going to charge the trailer air tanks.
|

None of the above.

|
|
All of the above.
