Question: 1 / 400

What indicates that the air brake system is fully charged?

The brake lights turn on

The air pressure gauge indicates the system has reached the set maximum pressure

The air brake system is considered fully charged when the air pressure gauge indicates that the system has reached the set maximum pressure. This maximum pressure is critical because it ensures there is sufficient air available for effective braking. A fully charged system indicates that the air compressor has done its job of replenishing the air tanks to the necessary level to ensure brakes respond when applied.

Having the correct pressure is essential for safe and effective braking performance in vehicles equipped with air brakes. When the system is fully charged, not only does it enhance the vehicle's ability to stop promptly, but it also helps ensure that the system functions reliably under various conditions. This level of readiness is crucial for preventing brake failure and maintaining safety on the road.
