a. The S-Cam may not rotate back when you release the brake pedal
b. Ice may form in the air storage tanks or air lines and cause brakes to fail
c. Ice may form on the brake drums and warp them

Answer 1

If the alcohol evaporator in an air brake system is not kept filled, ice may form in the air storage tanks or air lines and cause the brakes to fail.

Step-by-step explanation:

If you don't keep the alcohol evaporator in an air brake system filled, a possible consequence is that ice may form in the air storage tanks or air lines and cause the brakes to fail. The alcohol evaporator is responsible for preventing the buildup of moisture in the brake system. When it is not filled, moisture can accumulate and freeze in cold weather, leading to brake failure.
