What kind of maintenance is done in response to a breakdown?

Corrective maintenance is performed after a breakdown has occurred. This type of maintenance focuses on repairing equipment or systems that have malfunctioned or failed. It involves identifying the problem, fixing it, and restoring the equipment to normal operation. This reactive approach typically occurs in response to unplanned events, such as equipment failures, and is crucial for minimizing downtime and restoring service quickly.

Preventive maintenance, on the other hand, consists of routine check-ups and scheduled tasks that are intended to prevent potential failures before they happen. Predictive maintenance is based on monitoring equipment conditions to forecast when maintenance should be performed, allowing for timely interventions before failures occur. Scheduled maintenance refers to any maintenance performed at planned intervals, often based on time or usage, rather than in response to an actual failure.

Thus, corrective maintenance specifically addresses the immediate need following a breakdown, making it the appropriate answer.
