Alberta Air Brake Test 02

From understanding air brake system components and their functions to conducting pre-trip inspections, the practice test rigorously prepared you with the knowledge and skills required to pass the official exam with flying colors. Additionally, the test helped build my confidence as I became more familiar with the exam format. Ultimately, passing the Alberta Air Brake exam brought a great sense of accomplishment, knowing that I thoroughly understood air brake systems and the ability to operate commercial vehicles safely.

13 / 30

What are air dryers designed to do?

Removes contamination from the air pressure being delivered by the air compressor

Pushed the air through the air hoses

It dries the air

Sends information to the dashboard gauges

14 / 30

How often should you drain the supply tanks?

Once you notice contamination

Only if the gauges show a problem

During pre-trip inspections, enroute inspections and fueling

Never

15 / 30

Which statement is false? The supply tank functions:

It's the first tank that receives air pressure from the compressor

Tends to be a larger tank

It collects contamination not captured by the air dryer

Distributes to the two service tanks

They're all the same

Hydraulic brakes

Mechanical brakes

Air brakes

17 / 30

Do you need to wear any personal protective equipment when servicing air system work?

When releasing the air system

Only if close to the engine

Yes

None of the above

18 / 30

Whose responsibility is it to ensure the air brakes are working properly?

What controls the compressor as needed to maintain air pressor?

The senator

The premier

The governor

The president

20 / 30

What do Inline Alcohol Injectors do?

Cleans the air hoses

Adds vaporized air line antifreeze to the air supply

Polishes the compressors

Helps to fill the compressors

21 / 30

The air compressor is directly driven from where?

Fan belts

The internal gearing of the engine

A separate generator

A separate pump

22 / 30

What is a lanyard pull cable used for?

To secure the air hoses to the tank

To tighten the air hoses

To attach the drain valves to the tank

The open the drain valves

23 / 30

What's the purpose of safety valves?

Allows the brake hoses to be replaced easily

Just a safety thing

Protects the system from being over-pressurized

Allows the cylinders to be cleaned

24 / 30

What is the standard way to measure air pressure?

Litres per inch

Using Pounds Per Square Inch (PSI)

Square footage

Inches

25 / 30

An Original Equipment Manufacturer (OEM) may use kilopascal's (kPa). What does this measure?

Trailer weight

Vehicle weight

None of the above

Air pressure

26 / 30

Where is the driver when control and quick release valves exhaust forcefully?

Outside the vehicle

Under the hood

Doing routine maintenance

Inside the cab

27 / 30

When does contamination drain most effectively?
