Which type of maintenance includes inspecting brakes and wheels?

Preventive maintenance is focused on regularly scheduled inspections and upkeep to ensure that equipment operates efficiently and safely, thereby avoiding unexpected failures. Inspecting brakes and wheels is a critical aspect of this type of maintenance, as these components are vital for the safe operation of rail systems. By conducting routine check-ups on brakes and wheels, potential issues can be identified and addressed before they lead to more serious problems or accidents.

Corrective maintenance refers to repairs made after a breakdown has occurred, while deferred maintenance involves postponing necessary maintenance tasks, often leading to further complications. Predictive maintenance is based on data and analytics to foresee potential failures and schedule maintenance accordingly. Preventive maintenance, however, emphasizes proactive care to maintain safety and reliability, which is why it is the correct choice for the question about inspecting brakes and wheels.
