Question: 1 / 400

What is the maximum leakage rate for single vehicles?

1 psi per minute

2 psi per minute

The maximum leakage rate for single vehicles is set at 2 psi per minute. This standard is critical for ensuring the safe operation of commercial vehicles. A vehicle with excessive air leakage can face brake failure or reduced braking efficiency, which significantly heightens the risk of accidents.

Maintaining a lower leakage rate indicates that the air brake system is well-functioning and that there are no significant leaks in the system. The acceptance of 2 psi per minute is based on industry guidelines that focus on safety. This threshold balances the need for a functional system while allowing for some minor variations that can occur during normal usage.

Understanding this standard is essential for vehicle safety checks and compliance with regulations that govern commercial driving. Ensuring your vehicle meets this leakage rate helps maintain proper braking performance and overall operational safety.
