Brake System

What is the purpose of an air compressor in an air brake system?

• The purpose of an air compressor in an air brake system is to cool down the air.

• The purpose of an air compressor in an air brake system is to increase the pressure in the brake lines.

• The purpose of an air compressor in an air brake system is to compress air and supply it to the air reservoirs.

• The purpose of an air compressor in an air brake system is to release air from the reservoirs.

What is the role of an air reservoir in an air brake system?
