Operation & SafetyPregunta 53 de 60
If your air brakes fail and pressure drops, what safety feature will eventually stop the vehicle?
a.The service brake pedal alone
b.The trailer hand valve
c.The spring (emergency/parking) brakes applying automatically
d.The alcohol evaporator
Explicación
If air pressure drops too low, the spring brakes apply automatically because there is no longer enough air to hold the springs back. This is designed to stop the vehicle when the air system fails. However, the driver should react early to a low-pressure warning rather than wait for automatic application.
