When should a driver consider replacing brake pads?

A driver should consider replacing brake pads when they hear squeaking noises because these sounds are often indicative of wear on the brake pads. Many brake systems are equipped with wear indicators that create a high-pitched noise to alert the driver that the brake pads are nearing the end of their life. This sound serves as a crucial warning sign that, if ignored, could lead to decreased braking performance and potentially dangerous driving conditions. Therefore, paying attention to such auditory cues is essential for maintaining vehicle safety and ensuring effective braking.

The other scenarios, such as low fluid lights, vehicle starting issues, or the need for windshield wiper replacement, do not relate directly to the condition of the brake pads and thus are not indicators for their replacement.
