What should you check for if you experience a loss of braking power?

Tire pressure
Transmission fluid
Air pressure
Engine oil

The correct answer is: Air pressure

Experiencing a loss of braking power can often be attributed to issues within the air brake system, which is crucial for effectively stopping a vehicle equipped with air brakes. Checking the air pressure is essential because the braking system relies on compressed air to function correctly. Insufficient air pressure can lead to brake failure, as the brake chambers will not be able to activate, resulting in decreased or complete loss of braking power. Maintaining optimal air pressure ensures that the brakes engage properly when needed. If the air pressure is too low, it can affect the performance of the brakes significantly, potentially leading to dangerous situations. Therefore, making sure that the air pressure is at the recommended levels is critical for the safe operation of vehicles equipped with air brakes.
