19 . Where is the safety relief valve usually located?
On the dashboard
An air brake system's safety relief valve is located in the tank that is first to receive air from the compressor.
20 . What happens if the air pressure in a system's air tanks falls below 60 psi?
The vehicle should stop.
In an air brake system, a low pressure warning signal should activate if the pressure in the air tanks falls to a level below 60 psi. This signal may be in the form of a warning light or a wig wag.
21 . Most heavy-duty vehicles use:
Quadruple air brake systems.
Most heavy-duty vehicles use dual air brake systems, in which there are two separate braking systems operated by a single set of controls. Each system operates the brakes on different axles.
22 . 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.
23 . What is removed when an air tank is drained?
Chlorine
In an air brake system, the air storage tanks are equipped with drains to allow water and compressor oil to be removed. The water and oil can damage the brakes if left to accumulate in the system.
24 . During an applied leakage test, the maximum leakage rate for a single vehicle with air brakes is:
4 psi in one minute.
It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.
25 . When only the tractor is equipped with an Anti-Lock Braking System (ABS):
The brakes will become more sensitive.
If a tractor is equipped with an Anti-Lock Braking System (ABS) but the trailer is not, the risk of jackknifing will be reduced and the driver should still be able to maintain steering control. If only the trailer is equipped with ABS, it is less likely that the trailer will swing out to one side.
