13 . An Anti-Lock Braking System (ABS):
Should only be used if all axles have ABS.
Anti-Lock Braking Systems (ABS) are compatible with air braking systems. ABS helps maintain control of a vehicle and prevents the wheels from locking up during hard braking on slippery surfaces. ABS can still provide benefits even if is present on only one axle.
14 . To inspect slack adjusters on S-cam brakes, you need to:
Chock the wheels and disengage the parking brake.
Check each slack adjuster after parking on level ground, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.
15 . The air compressor governor controls:
The speed of the vehicle.
In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.
16 . Front brake limiting valves were intended to:
Remove uncertainty when applying the brakes.
Some older vehicles with air brakes have front brake limiting valves. These valves were intended to reduce the risk of front wheels skidding. However, research has shown that such devices are unnecessary, so they should be left in the "normal" position.
17 . The air entering air storage tanks may contain:
Antifreeze.
The air that enters air storage tanks in an air brake system usually contains a certain amount of water and compressor oil. Because accumulations of these materials can damage the braking system, tanks are equipped with drains to allow their removal.
18 . Air tank drains:
Must remain open while driving.
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. Manually operated air tank drains must be opened daily to remove this build-up.
