Air Brakes Test 5

1. If your vehicle has an alcohol evaporator, every day during cold weather you should:
Clean the air filter with alcohol.
Check and fill the alcohol level.
Change the alcohol from a new bottle.
Check the oil for alcohol content.

2. During normal driving, spring brakes are usually held back by:
Spring pressure
Bolts or clamps
Centrifugal force
Air pressure

3. Air braking takes more time than hydraulic braking because air brakes:
Need to have airflow through the lines to work.
Use different brake drums.
Require heavier return springs.
All of the above.

4. In air brake vehicles, the parking brakes should be used:
To hold your speed when going downhill.
Whenever the vehicle is parked.
As little as possible.
Only during pre and post trip inspections.

5. The brake pedal in an air brake system:
Is to be used as a footrest during normal driving.
Controls the speed of the air compressor.
Controls the air pressure applied to put on the brakes.
Is connected to slack adjusters by a series of rods and linkages.
