What can lead to a complete clutch failure?

Excessive slippage is a critical factor that can lead to a complete clutch failure. When the clutch slips, it means that it is not fully engaging or disengaging as intended, leading to a loss of power transmission from the engine to the wheels. This can cause overheating due to the increased friction between the clutch plates, resulting in wear and damage over time. If the slippage continues, it can lead to the clutch plates becoming burnt or warped, ultimately resulting in total failure where the clutch can no longer engage properly.

The other options contribute positively to clutch performance or have no negative impact. Proper clutch engagement ensures that power is transferred efficiently, while regular maintenance helps address potential problems before they escalate. Low RPM operation does not inherently lead to clutch failure and can occur without issues if managed correctly. These factors contrast with excessive slippage, which directly undermines the clutch's function.
