1 . What kind of force must emergency brakes use?

Electrical Because air pressure can eventually leak away, the emergency brakes in an air brake system must be held on by mechanical force.

2 . How is the parking brake released?

By tapping the accelerator twice In vehicles with air brakes, the parking brake is controlled by a knob. The knob is pulled out to apply the brakes, and pushed in to release them.

3 . 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.

4 . If the brake pads rub against the brake drums and create too much heat:

The air compressor will kick on to cool the brakes. Brakes heat up with use. If they are overused and become too hot, expansion and chemical changes will make them less effective and eventually cause them to stop working altogether. This is known as "brake fade."

5 . In cold weather, an alcohol evaporator should be checked and filled:

Once a month. An alcohol evaporator can help prevent ice from building up in an air brake system. In cold weather, the evaporator should be checked and refilled every day.

6 . What does the air compressor governor do?

Controls the temperature of the air leaving the air storage tanks. In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.
