InspectionPregunta 39 de 60
Why should you drain the air tanks and check for oil or water before a trip if the tanks do not have automatic drains?
a.To remove moisture and oil that could damage the brakes or freeze
b.To increase the air pressure
c.To speed up the compressor
d.To test the parking brake knob
Explicación
Air tanks collect water and compressor oil, so tanks without automatic drains must be drained manually. Removing this buildup prevents freezing in cold weather and protects brake components. A lot of oil in the tanks can indicate a compressor problem.
