Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. The Brake warning light can be illuminated for several reasons, including a difference in pressure between the two brake hydraulic circuits, which could indicate a leak or failure in one part of the system, and a low fluid level in the master cylinder reservoir, which could indicate a leak or that brake pads are worn and need replacement.
