Each system uses the same lines and hoses.

One system is the main braking system and a second system is ready to be used if the first one fails.

A dual air brake system is made up of two separate air brake systems. The systems share a single set of brake controls, but each has its own air tanks, hoses, and lines.

5 . Brake linings should be:

Loose.

Free of oil.

Soft.

Brake linings should not be loose or soaked with oil or grease. They shouldn't be dangerously thin.

6 . 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.
