What is the maximum allowable leakage rate for a single vehicle with brakes off?

• A. 1 PSI/min
• B. 2 PSI/min
• C. 3 PSI/min
• D. 4 PSI/min

Answer: (B)

The maximum allowable leakage rate for a single vehicle with the brakes off is 2 PSI per minute. This standard is important for ensuring the safety and reliability of the braking system in commercial vehicles. A leakage rate above this threshold can indicate problems such as worn seals, faulty components, or air line leaks, which could lead to a failure of the braking system when it is most needed. Maintaining the proper leakage rate helps to ensure that the air brakes can maintain adequate pressure for effective braking performance. By adhering to this standard, drivers and vehicle operators can help prevent potential accidents and ensure compliance with safety regulations. Regular inspections and maintenance should focus on identifying and addressing any leaks in the system to keep the vehicle safe and reliable on the road.
