The air brake system relies on which component to provide compressed air?

• A. Air Compressor
• B. Air Dryer
• C. Reservoir
• D. Brake Chamber

Answer: (A)

In an air brake system, the source that creates the pressurized air is the air compressor. It draws in ambient air and pumps it up to the system’s operating pressure, supplying the reservoirs and the rest of the lines. The other parts have important roles but don’t generate the pressure: the air dryer removes moisture to keep the air clean and prevent freezing or corrosion, the reservoirs store the compressed air for instant use, and the brake chamber uses the stored air to actuate the brakes when you apply them. So the air compressor is the component that provides compressed air.
