Some air brake systems have an alcohol evaporator. What may happen if you don't keep the proper level of alcohol?

Question

Accepted Answer

B: Ice may form in the air brake valves and cause brake failure.. The purpose of an alcohol evaporator is to remove water from the air in the air brake system. Compressing air often causes condensation so the water needs to be removed. Alcohol attracts moisture and transports it to the evaporator. Failure to remove the air can cause the water to freeze in the system.
