In an air brake system, what is the purpose of the air storage tanks?
Correct answer: They hold compressed air until the brakes need it.
Answer options
AThey hold compressed air until the brakes need it Correct
BThey are driven by the engine through a V-belt or gears
CThey signal the compressor to stop pumping air
Why
These tanks, also known as reservoirs, keep a supply of compressed air ready for braking and hold enough for several brake applications if the compressor stops working. The governor is what tells the compressor when to stop pumping, and the compressor is the part the engine drives.
