1 . Why do you need to drain air tanks regularly?

Because the air gets old and needs to be replaced

Because compressed air contains some water which must be drained from the tanks

To allow for a change in air pressure

To remove bad air from the tanks

Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Tanks must be drained regularly to remove this build-up.

2 . If using air tanks with manually operated drains, how often should you drain the tanks?

Every day

Once a week

Once a month

Once every 3,000 miles

To prevent the build up of oil and water in a vehicle's air tanks, manually operated air tank drains should be used at the end of each day of driving.

3 . A dual air brake system:

Has a single air brake system, but uses two sets of controls.

Has one air brake system for each side of the truck.

Has two brakes for each wheel.

Has two separate air brake systems, but uses a single set of controls.

A dual air brake system has two separate air brake systems that use a single set of brake controls. One system typically operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle.

4 . How many air storage tanks are used in an air brake system?

Two tanks

Four tanks

Six tanks

The number varies.

Air storage tanks are used to hold compressed air. The number and size of air tanks in an air brake system varies among vehicles.

5 . An alcohol evaporator in an air brake system:

Makes the brakes work without squeaking.

Prevents ice from forming in the braking system.

Lubricates parts of the braking system.

Some air brake systems include an evaporator that introduces alcohol into the system. The alcohol can help prevent ice from forming within the system.

6 . Before starting down a hill, be sure to:

Accelerate.

Switch into a high gear.

Sound your horn.

Switch into a low gear.

Before starting down a hill, be sure to switch into a low gear. Gravity will increase your vehicle's speed as you travel downhill.
