In regards to air brakes on a truck, what happens when a service line ruptures?
Understand the Problem
The question is asking about the consequences or effects of a rupture in the service line of air brakes on a truck. This involves understanding the functionality of air brake systems and the impact of a failure in the service line.
Answer
Service line rupture causes air to escape, potentially activating the tractor protection system, shutting off the trailer's supply line.
When a service line ruptures or is disconnected on a truck, air pressure begins to escape. If a brake is applied long enough for the pressure to drop significantly, the tractor protection system will activate, shutting off and exhausting the supply line to the trailer.

More Information
When a service line rupture occurs, it could lead to a loss of control if the driver isn't aware and doesn't adjust. The tractor protection system helps in maintaining safety by isolating the trailer if major leaks occur.
Tips
A common mistake is not being aware of the potential for loss of air pressure when a service line ruptures. Ensuring all lines are properly connected and inspected regularly can help avoid this issue.
