How long should a brake pedal hold pressure during a brake inspection?

During a brake inspection, it is crucial to assess the functionality of the brake system, and one of the key tests involves checking how long the brake pedal can hold pressure. A duration of 1 minute is considered optimal for this test, as it allows inspectors to determine if there's any loss of pressure which could indicate issues such as leaks or air in the brake lines.

Maintaining pressure for this length of time ensures that the hydraulic systems are working properly. If the pedal sinks during this test, it signifies that there's a problem that needs to be addressed, reflecting on the overall safety and reliability of the vehicle's braking system.

This 1-minute test strikes a balance between thoroughness and practicality, ensuring that the brakes are not only functional but also capable of performing reliably under normal operating conditions.
