Nova Scotia Air Brake Practice Test 2025 – Complete Exam Prep

Question: 1 / 400

What is the maximum air pressure loss allowed on a full brake application with the motor off?

2 psi per minute

3 psi per minute

The maximum air pressure loss allowed on a full brake application with the motor off is 3 psi per minute. This standard is crucial for ensuring the reliability and effectiveness of the air brake system. A loss of 3 psi indicates that the air brake system is functioning within acceptable limits, ensuring that there are no significant leaks that could compromise braking performance.

Maintaining this limit is essential for safety, as any excessive loss of air pressure may suggest issues within the air brake system, such as leaks or faults in components. The tolerance level is set to allow for normal variations in pressure loss while ensuring the system remains reliable under various conditions. Each other option suggests a different acceptable level of pressure loss, but they either exceed or do not align with the established safety standards for air brake systems in vehicles, which emphasize the importance of a maximum of 3 psi per minute for optimal safety and performance.
