19 . Foundation brakes are used:
At each wheel.
Foundation brakes are used at each wheel. The most common type is the S-cam drum brake.
20 . 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.
21 . 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.
22 . The air compressor governor controls:
The speed of the vehicle.
In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.
23 . Why do large vehicles use air brakes?
Air is free.
Air brakes are an effective and safe way of stopping large and heavy vehicles, as long as they are maintained and used properly.
24 . What can happen if parking brakes are used in very wet weather with temperatures below freezing?
The brakes may become too smooth to be used.
Parking brakes should not be used in very wet weather when temperatures are below freezing. The brakes could become frozen in place, making it impossible to move the vehicle.
25 . A tank endorsement is:
Optional when transporting hazardous materials.
With some exceptions, you must have a tank endorsement to transport liquids or gases. This applies to both hazardous and non-hazardous substances.
