7 . Air brakes are:
A tool to improve fuel efficiency.
As long as the brakes are properly maintained, using air brakes is a safe and effective method of stopping large, heavy vehicles.
8 . 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.
9 . Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when:
Driving uphill.
Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when air tank pressure falls to a level between 20 and 45 psi. You can do this by chocking the wheels and releasing air from the braking system by stepping on and off the brake pedal. Once the pressure drops to an unsafe level, the parking brake valve should pop out and spring brakes should come on.
10 . What happens if brakes become too hot?
The air compressor will kick in to cool the brakes
If brakes are overused, they may overheat and stop working. This is referred to as brake fade.
11 . Anti-Lock Braking Systems (ABS):
Are illegal in some states.
ABS is equipped in addition to a vehicle's normal braking system and it neither increases nor decreases the vehicle's braking capability. ABS activates during hard applications of the brake pedal in order to prevent wheels from locking up.
12 . 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.
