1 . Why do you need to drain air tanks regularly?
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?
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 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?
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:
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:
Switch into a low gear.
