13 . To stop in a vehicle that uses air brakes, the driver should:
Pull the brake pedal up.
To make a normal stop in a vehicle with air brakes, push the brake pedal down. The harder the pedal is pressed, the more air pressure is released.
14 . 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.
15 . Vehicles with dual air brake systems:
Do not need time to build air pressure before a trip.
Before driving a vehicle with a dual air brake system, you must allow the air compressor time to build up at least 100 psi of air pressure in both the primary and secondary systems.
16 . When the brake pedal is pushed down, air brakes work:
Only if it is warm outside.
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.
17 . If the air pressure warning light comes on, you should:
Safely exit the roadway and stop.
If the air pressure warning light or buzzer comes on while you are driving, you should immediately stop and safely park the vehicle. This warning signal indicates that there is a problem in the air brake system that needs to be fixed.
18 . What can happen if the air pressure gets too low in an air brake system?
The brakes will be very sensitive.
Pressing and releasing the brake pedal unnecessarily can let air out faster than the compressor can replace it, reducing the available air pressure. If the air pressure in an air brake system gets too low, the brakes will no longer work.
