TN CDL AIR BRAKES PRACTICE TEST
6.
Slack adjusters:
|
are used to adjust the brakes on an air-brake system.
|
|
|
are the linkage between the operating rod in the brake chamber and drum brakes or disk brakes in an air brake system.
|
|
|
regulate the distance that the air brake has to travel to apply friction to the wheel.
|
|
|
All of the above.
|
7.
If you must make an emergency stop, you should:
|
apply the brakes as hard as you can to lock them.
|
|
|
use the hand brake before the brake pedal.
|
|
|
brake in a way that will keep your vehicle in a straight line.
|
|
|
None of the above.
|
8.
Some air brake systems have an alcohol evaporator. Checking the alcohol container and filling it up as necessary:
|
helps keep the engine cool, as well as lubricating it.
|
|
|
reduces the risk of ice in air brake valves during cold weather.
|
|
|
helps you avoid wheel lock up.
|
|
|
reduces the risk of having an accident due to drowsy driving.
|
9.
Pressing and releasing the brake pedal unnecessarily can:
|
let air out faster than the compressor can replace it.
|
|
|
causes friction, which slows the vehicle.
|
|
|
causes all the air to be lost.
|
|
|
apply more air pressure.
|
10.
Weight that is loaded so there is a high center of gravity:
|
reduces the chance that the load will shift to the side or fall off.
|
|
|
causes greater chance of rollover.
|
|
|
makes a vehicle easier to handle.
|
|
|
All of the above.
