They'll be caged when you remove them. They must be uncaged before they are opened up and/or disposed of.
Semi-trucks are equiped with two brake lines. One in the normal air brake line and the other is the emergency air brake line. If your normal breaks fail, the emergency break will automatically switch on so you will be safe until you can stop. That is how you will tell your breaks fail-your emergency break will initiate.
Most air brake systems are fail-safe. This means that if there is a failure in the pressure system the brakes will lock on. You need gauges to show that you have sufficient pressure to proceed and to know your brakes are not dragging as this would cause them to overheat.
The brake light switch is not air actuated.

Railway air brake was created in 1872.
Then you need to bleed the brake system to remove the air.
The brake pedal has nothing to do with it. If air is in the system then bleed the brakes.
The water coming out of the air conditioner is condensation from the air as it is dehumidified. It cannot be stopped (nor do you want to). Either collect it and dispose of it or set up a drain line to dispose of it.
More info, please. Namely, are you talking about an air brake system? You should hear some air as you apply and release the brake, but you shouldn't hear a continuous air sound as the brake is applied - if so, you've probably got a compromised air line or a bad brake chamber.
If it's a job which requires a CDL, then you cannot have the "no air brake" restriction. There is no such thing as an "air brake license" in the US.
