What light typically comes on if one of the dual hydraulic brakes fails?

The correct answer is that the specific light that typically comes on if one of the dual hydraulic brakes fails is the Brake Failure Light. This light serves as a crucial signal to the driver that there is an issue with the braking system, particularly when one of the dual circuits within the hydraulic brake system is not functioning properly.

When one part of the dual hydraulic braking system fails, the system is designed to still maintain some level of braking capability, but it will trigger the Brake Failure Light to alert the driver to the malfunction. This allows the driver to take immediate action, ensuring their safety and the safety of others on the road. Being aware of this light is essential, as ignoring it could lead to brake failure and significantly increase the risk of a collision.

Understanding the function of this light emphasizes the importance of regular vehicle maintenance and prompt attention to warning signals, an essential aspect of safe driving practices.
