What should be done after making a brake pipe exhaust stop during pressure reduction?

After making a brake pipe exhaust stop during pressure reduction, it is important to wait a specific amount of time, typically around 30 seconds, to allow the system to stabilize. This waiting period is crucial because it ensures that the pressures within the brake system have had enough time to equilibrate before moving on to the next action. If you immediately recharge the system or release the automatic brake valve without allowing the necessary time for stabilization, you could risk creating pressure discrepancies that could lead to inefficient braking or possibly a safety hazard.

Checking the pressure gauge is also an important step, but it should be done during or after the wait period, not immediately following the exhaust stop, as the gauge may not accurately reflect the system's state until equilibrium is achieved. Thus, the correct procedure involves patiently waiting for at least 30 seconds to ensure the stability and reliability of the braking system.
