Just as it states, you fix it when it breaks.

The inadequacies of this type of maintenance are numerous. First, consider the monetary cost and the cost of not servicing your customer efficiently. Breakdowns always seem to occur in off hours and in remote unserviced locations. This means an expensive road call, tow bill and more down time compared to a scheduled shop visit. Secondly, just as OM controls the life cycle cost of your equipment, it also maximizes the service life of individual components. Consider a loose alternator or A/C compressor mounting, a hose rubbing, wiring harness chaffing, electrical terminals corroding, front axle running out, wheel seal leaking, and so on going unattended. Left unchecked, such problems can cause unnecessary damage and unplanned expenses. Unlike PM, Break Down Maintenance does not have a schedule or controlled budget.
