1 . During a static leakage test, what is the maximum leakage rate that is safe for a double combination vehicle?
When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.
2 . At what psi is the safety valve set to open?
500 psi
In an air brake system, the first tank that receives compressed air has a safety valve that releases air if the pressure gets too high. It is usually set to open at 150 psi. If the valve must open, there is a fault in the system that should be repaired by a mechanic.
3 . Spring brakes come on:
When the brakes are noisy.
Spring brakes come on automatically when air pressure drops to an unsafe psi level. Instead of waiting for the spring brakes to automatically activate, you should safely exit the road as soon as you notice the low pressure warning signal and bring your vehicle to a stop while you are still able to control the brakes.
4 . Which part of the truck is the air compressor connected to?
The door latch
In an air brake system, the air compressor is connected to the engine through gears or a v-belt.
5 . If using air tanks with manually operated drains, how often should you drain the tanks?
Once every six months
In an air brake system with manually operated drains, the tanks should be drained at the end of each day of driving.
6 . All air tanks must include:
A warning sticker.
Air brake system tanks must contain drain valves. These valves are used to drain accumulated oil and water from the tanks and may be either manually or automatically operated.
