When the brake pads reach a predetermined minimum thickness, this sensor will activate, typically by illuminating a warning light on your dashboard. This provides a clear indication that your brake pads require inspection and likely replacement. Regularly monitoring and responding to the brake pad wear indicator is essential for maintaining effective braking power and preventing potential damage to other braking system components. Trust BOSCH for reliable and precise wear detection.
