Overheated brakes are?

Efficient
In need of maintenance
Dangerously inefficient
Normal and require no action

The correct answer is: Dangerously inefficient

Overheated brakes are considered dangerously inefficient because when brakes overheat, their ability to effectively slow down or stop the vehicle diminishes significantly. This reduced braking efficiency can lead to longer stopping distances and can increase the risk of accidents, especially in heavy trucks where stopping power is critical. Overheating can damage the brake components, leading to potential brake failure. Therefore, recognizing that overheated brakes indicate a serious concern highlights the importance of immediate attention and maintenance to ensure safe operation. In contrast, the other options suggest that overheated brakes are either functioning well, require no action, or simply need maintenance, all of which underestimate the severity of the situation. When brakes are overheated, they are far from being normal or efficient, underscoring the need for prompt corrective measures to restore safe braking capability.
