Final answer:
The correct option is D) your brakes won't be affected. In an air brake system, if the air compressor stops working, your brakes won't be affected. However, the efficiency of the brakes may be affected.
Step-by-step explanation:
In an air brake system, if the air compressor stops working, your brakes won't be affected. This is because the air pressure that is stored in the air tanks will still be available to operate the brakes.
The air compressor is responsible for compressing air and supplying it to the air tanks. The air tanks store the compressed air and provide it to the brake system when needed. Even if the compressor stops working, there will still be air pressure left in the tanks, allowing the brakes to continue functioning.
However, it is important to note that the efficiency of the brakes may be affected. When the force is applied to the brakes, the air in the brake lines may need to be bled out in order for the brakes to work properly. This is because gas is compressible, and when it is compressed, it can warm up and decrease in efficiency. Bleeding the air out of the brake lines ensures that the brakes operate at their optimal performance.
