What is checked as part of the brake system inspection?

The brake system inspection is a comprehensive evaluation of essential components that are crucial for safe vehicle operation. This includes checking the brake pads, rotors, and overall functionality of the brakes. The brake pads are inspected for wear and thickness, as worn pads can significantly reduce braking effectiveness. The rotors are examined for any signs of damage, warping, or excessive wear that may affect braking performance. Additionally, the functionality of the entire braking system is assessed to ensure that it responds appropriately when the driver applies the brakes. This thorough assessment is vital for maintaining vehicle safety and ensuring that drivers can rely on their braking system under various driving conditions.

In comparison, simply checking the brake fluid level does not provide a complete picture of the brake system's health. While the brake fluid is an important part of the hydraulic system, it needs to be in proper condition alongside other components for the brakes to function correctly. The option regarding brake lights and the horn pertains to other safety features of the vehicle but does not directly relate to the braking system itself. Lastly, only checking the brake pads does not cover all the necessary aspects of the braking system that are essential for safe vehicle operation.
