What is the maximum leakage rate during a static leakage test for a single vehicle with air brakes?

1 psi
2 psi
3 psi
4 psi

The correct answer is: 2 psi

The maximum leakage rate during a static leakage test for a single vehicle with air brakes is set at 2 psi. This standard is implemented to ensure that the vehicle's air brake system is functioning efficiently and safely. During the static leakage test, the vehicle's air pressure is allowed to stabilize before checking for any pressure drop over a specified period, usually one minute. If the pressure loss exceeds the acceptable limit, it indicates potential issues with the air brake system, such as leaks or other complications that could impair braking performance. Maintaining a maximum leakage rate of 2 psi helps ensure that the air brake system is secure and reliable, reducing the risk of brake failure while driving. The established standards for air brake systems are critical for the safety of the driver, passengers, and others on the road.
