1 . An alcohol evaporator is especially important:

Some air brake systems contain an alcohol evaporator. This evaporator introduces alcohol into the system to help prevent ice from forming in cold weather.

2 . A safety valve is set to open at ____ pounds per square inch (psi).

The safety valve protects air tanks and the rest of an air brake system from accumulating too much air pressure. The safety valve is usually set to open at 150 psi.

3 . What is often found in compressed air?

Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Tanks must be drained regularly to remove this build-up.

4 . During an applied leakage test, the maximum leakage rate for a double combination vehicle is ____ in a minute.

It is important to know the maximum air loss rate that is safe for your specific vehicle. A double combination vehicle should have a leakage rate no higher than 4 psi in a minute during an applied leakage test.

5 . Brakes can get out of adjustment quickly, especially:

Brakes are particularly prone to getting out of adjustment if they are hot. Be sure to routinely check the adjustment of your brakes. For a vehicle to be safely controlled, all brakes must be properly functioning and adjusted.

6 . A driver can rely on front wheel braking to work:

Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.
