In an air brake system, which statement about the storage tanks is true?
Correct answer: They hold enough air for several brake applications if the compressor fails.
Answer options
AThey hold only enough air for one brake application, then must be refilled.
BThey hold enough air for several brake applications if the compressor fails. Correct
CThey stay empty and fill with air only when an emergency stop is needed.
Why
The storage tanks keep a reserve of compressed air for the brakes, large enough that you can still brake several times after a compressor failure and bring the vehicle to a safe stop.
