1 . How is water and compressor oil removed from the bottom of an air storage tank?
A sponge is used to soak up the water and oil.
Water and compressor oil are removed from air storage tanks through a drain valve. The water and oil can damage the brakes if left to accumulate in the system. Manually operated tanks must be drained every day to remove this build-up.
2 . 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.
3 . When you press the brake pedal in a vehicle with S-cam brakes, air pressure pushes out the rod and moves the:
Alcohol evaporator.
When pressing the brake pedal in a vehicle with S-cam brakes, air will enter the brake chambers. The added air pressure will push out the rods and move slack adjusters, twisting the brake camshafts.
4 . What does ABS do?
Prevent the brakes from being used if downshifting would be more effective
The purpose of an Anti-Lock Braking System (ABS) is to prevent wheels from locking up during hard applications of the brakes, especially on slippery surfaces.
5 . If the low pressure warning signal activates while you are driving, you should:
Put on your hazard lights and continue driving.
If the low pressure warning signal activates while you are driving, it is important that you safely exit the roadway as soon as possible and park your vehicle. If the air pressure gets too low, the brakes will no longer work well enough for you to stop safely.
6 . In a dual air brake system:
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.
