Which components should not be missing or broken in the brake system?

The brake system of a vehicle is crucial for safe operation, and each component plays a specific role in ensuring effective braking performance. The choice indicating that shoes, pads, drums, lining, and anchor pins should not be missing or broken is correct because these components directly contribute to the vehicle's ability to stop safely and efficiently.

Brake shoes and pads are essential for creating the friction needed to slow or stop the vehicle when the brakes are engaged. Drums and linings also work together in braking systems, especially in drum brake setups, to ensure that the brakes can perform adequately. Anchor pins serve to secure these components in place, making them critical for the structural integrity and functionality of the entire brake system.

If any of these components are missing or broken, it can result in a significant decrease in braking efficiency, potentially leading to unsafe driving conditions. Therefore, ensuring the integrity of these components is vital for the safety and reliability of the vehicle's brake system.
