19 . Air brakes are:
A tool to improve fuel efficiency.
As long as the brakes are properly maintained, using air brakes is a safe and effective method of stopping large, heavy vehicles.
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 . Anti-Lock Braking Systems (ABS):
Are illegal in some states.
ABS is equipped in addition to a vehicle's normal braking system and it neither increases nor decreases the vehicle's braking capability. ABS activates during hard applications of the brake pedal in order to prevent wheels from locking up.
22 . Front wheel braking works:
Under most conditions.
Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.
23 . In a newer vehicle, you apply the parking brake:
By using a black round knob.
In a newer vehicle with air brakes, the parking brake is controlled by a diamond-shaped yellow knob. The knob is pulled out to apply the parking brakes and pushed in to release them.
24 . Foundation brakes are used:
At each wheel.
Foundation brakes are used at each wheel. The most common type is the S-cam drum brake.
25 . 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.
