Question 1

What is the primary function of the air compressor governor in a commercial vehicle dual air brake system?

To lubricate the brake drums and linings with oil mist To control when the air compressor pumps air into the storage reservoirs by managing cut-in and cut-out pressures To measure engine coolant temperature To apply the parking spring brakes automatically when changing gears

Correct Answer:

To control when the air compressor pumps air into the storage reservoirs by managing cut-in and cut-out pressures

Question 2

What are standard operating pressure ranges for air compressor cut-in and cut-out in heavy vehicle air brake systems?

Cut-in at 40 psi and cut-out at 60 psi Cut-in around 100 psi and cut-out around 120 to 125 psi Cut-in at 150 psi and cut-out at 250 psi Cut-in at 10 psi and cut-out at 30 psi

Correct Answer:

Cut-in around 100 psi and cut-out around 120 to 125 psi

Question 3

The low air pressure warning device (buzzer and red dashboard light) on an air-braked vehicle is designed to alert the driver at what point?

Only after the spring brakes have already applied themselves automatically While enough reserve pressure still remains to bring the vehicle to a controlled stop Only when the reservoirs have emptied completely Only when reservoir pressure rises above the governor cut-out setting

Correct Answer:

While enough reserve pressure still remains to bring the vehicle to a controlled stop

Question 4

What happens automatically to a heavy vehicle's spring parking brakes if air pressure drops catastrophically below 20–45 psi?

The truck accelerates to full speed The heavy mechanical coil springs overcome remaining air pressure and apply the emergency parking brakes fully The transmission shifts automatically into neutral The steering wheel locks in the straight-ahead position

Correct Answer:

The heavy mechanical coil springs overcome remaining air pressure and apply the emergency parking brakes fully

Question 5

What is 'brake lag' in commercial vehicles equipped with air brake systems?

The delay caused by the driver deciding when to brake The physical time required for compressed air to travel through the airlines and chambers to actuate the brake shoes (approx. 0.4 to 0.5 seconds) The time it takes to replace worn brake pads in a workshop The delay caused by air conditioner compressors

Correct Answer:

The physical time required for compressed air to travel through the airlines and chambers to actuate the brake shoes (approx. 0.4 to 0.5 seconds)
