What is the function of the air compressor in a vehicle's air brake system?

Converts air pressure to fluid pressure
Cools the air in the system
Draws air in and increases air pressure
Filters contaminants from the air

The correct answer is: Draws air in and increases air pressure

The air compressor is responsible for drawing air into the air brake system and compressing it to the necessary pressure for the brakes to work. Option A is incorrect because the air compressor does not convert air pressure to fluid pressure, it maintains air pressure. Option B is incorrect because the function of the air compressor is not to cool the air, but to compress it. Option D is incorrect because the air compressor does not filter contaminants from the air, rather it compresses air from the environment.
