Air Brakes component Quiz

What is the basic principle of air brake operation?

• Friction is used to apply and release the brakes.

• Electricity is used to apply and release the brakes.

• Hydraulic fluid is used to apply and release the brakes.

• Compressed air is used to apply and release the brakes.

Name two essential components of an air brake system .

• Compressor

• governor

• intercooler

• blower

Describe the role of an air compressor in an air brake system and how it operates.

• The air compressor pressurizes the air used to operate the brakes by drawing in air and compressing it to a high pressure.

• The air compressor is used to cool down the engine

• The air compressor is responsible for steering the vehicle

• The air compressor releases air to slow down the vehicle

What are some common maintenance tasks for air brake systems?

• Checking for air leaks

• draining oil

• inspecting driveline

• Refilling the windshield washer fluid

How can air leaks in an air brake system be identified first?

• By ignoring the issue and continuing to operate the vehicle

• By listening for hissing or escaping air and locating the source of the leak to replace or repair the damaged component.

• By adding more air to the system till noise stops

• By replacing the entire air brake system

Tech A says brake foundations are the braking components found at the wheel ends. Tech B says the cam brakes system use a C-shaped cam between 2 rollers, who is correct.

• Tech A

• Tech B

• both

• neither

what component stops the air compressor from charging the air system?

• governor

• Check valve

• air dryer

• none of these components

What safety measures should be followed when working on air brake systems?

• Ignoring manufacturer's guidelines

• Starting work without depressurizing the system

• Wearing protective gear, depressurizing the system before starting work, and following manufacturer's guidelines

• Not wearing any protective gear

Why is it important to drain moisture from air brake systems and how can it be done effectively?

• To improve fuel efficiency, and it can be done effectively by releasing air from the system

• To reduce noise from the brakes, and it can be done effectively by adding water to the air tanks

• To increase the speed of the vehicle, and it can be done effectively by adding more air to the system

• To prevent corrosion and freezing, and it can be done effectively by regularly draining the air tanks and using air dryer systems.

Other than water, what else does a air dryer remove from the air being supplied to the brake and suspension system?

• NO2

• carbon

• DEF

• oil
