AIR BRAKES PRACTICE TEST - FLORIDA
11.
An Anti-lock Braking System (ABS):
|
keeps your wheels from locking up when you brake hard.
|
|
|
increases your normal braking capability.
|
|
|
lets you drive faster.
|
|
|
always shortens your stopping distance.
|
12.
Excessive use of the service brakes results in overheating and leads to:
|
poor traction.
|
|
|
reduction of the brake drums.
|
|
|
low air pressure.
|
|
|
brake fade.
|
13.
If the low pressure warning signal doesn't work:
|
in dual systems the stopping distance will be decreased.
|
|
|
you could lose air pressure and you would know it.
|
|
|
this could cause sudden emergency braking in a single-circuit air system.
|
|
|
None of the above.
|
14.
If your vehicle has dual parking control valves, you can use pressure from a separate tank to:
|
balance the service brakes while you are parked.
|
|
|
park better.
|
|
|
release the spring brakes so you can move the vehicle in an emergency.
|
|
|
None of the above.
|
15.
If your vehicle is equipped with air brakes, loss of air pressure in the
emergency line causes:
|
the trailer emergency brakes to come on.
|
|
|
the speed of your vehicle to increase.
|
|
|
the trailer spring brakes to come on.
|
|
|
All of the above.
