a.It makes the compressor run too slowly
b.In cold weather it can freeze and cause brake failure
c.It increases stopping distance on dry roads
d.It causes the low-pressure warning to stay on
Explanation
Water collecting in the tanks can freeze in cold weather, and frozen moisture can keep the brakes from working properly. That is why tanks must be drained regularly to remove accumulated water and oil. Some vehicles have automatic drain valves, but manual drains should still be checked.
