22 . When driving down a steep grade, your brakes may fade. What happens if brakes fade?
They work differently from front to back.
If you use your brakes too much when traveling on a steep downgrade, they may overheat and become less effective. To avoid causing your brakes to overheat on a steep hill, you should rely on engine braking.
23 . The air entering air storage tanks may contain:
Antifreeze.
The air that enters air storage tanks in an air brake system usually contains a certain amount of water and compressor oil. Because accumulations of these materials can damage the braking system, tanks are equipped with drains to allow their removal.
24 . If the low pressure warning signal activates while you are driving, you should:
Put on your hazard lights and continue driving.
If the low pressure warning signal activates while you are driving, it is important that you safely exit the roadway as soon as possible and park your vehicle. If the air pressure gets too low, the brakes will no longer work well enough for you to stop safely.
25 . The two indicators that determine when you should upshift are:
Oil pressure and air brake pressure.
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
26 . When you press the brake pedal in a vehicle with S-cam brakes, air pressure pushes out the rod and moves the:
Alcohol evaporator.
When pressing the brake pedal in a vehicle with S-cam brakes, air will enter the brake chambers. The added air pressure will push out the rods and move slack adjusters, twisting the brake camshafts.
27 . Which of the following is not a type of retarder?
Electric
Retarders are mechanisms in some vehicles that help slow a vehicle and reduce the need for braking. The four basic types of retarders are exhaust, engine, hydraulic, and electric.
28 . When asked to make a lane change during the skills test, you should:
Not make the lane change if you don’t want to.
You will be asked to make multiple lane changes during the driving skills test. Before changing lanes, you should make the necessary traffic checks and use proper signals. Change lanes smoothly when you can do so safely.
