BC Air Brake Practice Test 03

Taking the BC air brake practice test can be a nerve-wracking experience for those wanting to obtain their air brake endorsement. However, with proper preparation and practice, passing the official exam with flying colors is achievable. It is recommended to use certified training materials and take advantage of online practice tests to gain an in-depth understanding of the air brake system and regulations.

1 / 30

What is another name for the foot brake pedal?

Bar

Push rod

Treadle

Thread

2 / 30

Typically, where is the low-air warning device connected to?

The primary reservoir

The biggest tank

The secondary reservoir

The supply reservoir

3 / 30

Other than a leak, what could cause low-air pressure?

If you apply the brakes repeatedly and have used up the air supply more rapidly than the compressor can replenish it

If the compressor is too small

If the air lines are too thin

If the compressor is overheating

4 / 30

If there are two reservoirs, how many pressure gauges are there?

One

Four

Two

Three

5 / 30

What is the purpose of a dual air brake system?

It allows the brake system to be divided into two independent sections with each section having its own supply, delivery, and exhaust ports

They are in all new vehicles

No advantage whatsoever

Works better with tandem wheels

6 / 30

What is the second type of parking brake in an air brake system known as?

Air-over hydraulic

Safety actuator

None of the above

Cable

7 / 30

Some older vehicles are equipped with a low-air warning device near the top of the windshield that drops into the driver's view when air pressure drops. What is this?

A toggle

A woggle

A mig-mag

A wig-wag

8 / 30

What is another name for manually releasing an applied spring parking brake?

Sweeping

Pulling

Pushing

Caging

9 / 30

Many vehicles have a single gauge with two needles, indicating the pressure in which reservoirs?

Supply reservoir only but use for psi and kPa

Supply and primary reservoir

Supply reservoir and secondary reservoirs

Primary and secondary reservoirs

10 / 30

Does the foot control valve have the ability to maintain the application pressure that you've chosen, even if there is a small leak downstream from the foot valve?

Just for 2 to 3 seconds

Yes

Up to 5 seconds maximum

11 / 30

What is the purpose of the relay valve?

To reduce the lag time when the brakes are applied, and when they're released

To push air through the lines

To help apply the brakes quicker

To relay computerized messages from the brakes to the gauges

12 / 30

At what point does the low-air warning device come on?

When air pressure drops below 80 psi

When air pressure drops below 60 psi

When air pressure drops below 20 psi

When air pressure drops below 50 psi

13 / 30

What are the problems using the air brakes for parking?

Not enough air to hold the vehicle

Any loss of air pressure and a possible rollaway collision could happen

None of the above

The air will eventually leave the lines

14 / 30

What does a quick release valve do?

It stops the flow of air going into the reservoirs

None of the above

It controls the air flow

It allows the brakes to release quickly and fully, by allowing the pressurized air to exhaust near the brake chambers

15 / 30

When should caging of park brake actually be done?

Only in an emergency

Once you've traveled 160 km during that trip

Prior to leaving on your daily trip

Every 500 km

16 / 30

How often should you drain reservoirs?

Every 48 hours

Monthly

Daily

Weekly

17 / 30

What is the name of the line that air flows from the foot valve to the foundation brakes?

Governor line

Delivery line

Discharge line

Supply line

18 / 30

If the low-air pressure warning light comes on, what should you do?

Keep going but allow five times more to stop

Pull over and stop

Allow the compressor to build up more air before you stop

None of the above

19 / 30

What is meant by compounding air brakes?

When the park brake is not working

When the park brake is released at the same time as the service brake

When the service brake is not working

When a service brake application is made with the park brake still applied

20 / 30

Which reservoir usually has the most contaminants in it?

The supply reservoir

They all have the same amount

The secondary reservoir

The primary reservoir

21 / 30

How long have dual air brake systems been in use?

The last ten years

Since the mid-1970'

Since early 2000's

Since 1992

22 / 30

What's another name for a drain valve?

Drain holes

Drain cocks

Drain stems

Drain releases

23 / 30

In a dual air brake system, where is the air from the primary tank applied to?

To both front and rear axle brakes

To the rear axle brakes

To the front axle brakes

To whichever brakes need to be applied first

24 / 30

What do one-way check valves do?

They allow air to flow in both directions

None of the above

They allow air to flow from the supply reservoir to the primary and secondary reservoirs

They allow air to be exhausted through ports

25 / 30

In a dual air brake system, when brakes are applied, which section activates first?

It doesn't matter as long as it works

Primary tank first

Secondary tank first

Both sections are activated

26 / 30

In a dual air brake system, if one of the system totally fails, is the driver able to make a controlled stop?

Yes

Yes, but it will be much longer

Not unless the parking/emergency brake is also applied

27 / 30

What is the most common type of parking brake in an air brake system?

The hydraulic parking brake

The air parking brake

The cable parking brake

The spring parking brake

28 / 30

What happens when the driver releases the foot valve?

None of the above

Air pressure in the brake lines remains constant

Air pressure build back up

Air pressure in the brake chambers exhausts into the atmosphere

29 / 30

What type of vehicle are safety actuators typically used on?

Large tractor trailers

Buses and highway coaches

Fire trucks

Dump trucks

30 / 30

Where is the relay valve typically installed?

In front of the foot valve

Beside the governor

Right beside the quick release valve

Between the reservoir and the rear brake chambers
