Understanding the Mini Brake Pad Warning Light
The brake pad warning light, often a yellow or red symbol on your dashboard, illuminates when the brake pad wear sensor detects that the pads have reached a critical thickness. Ignoring this warning can lead to severe brake damage and compromise your safety. The light itself doesn’t signify a problem with the light, but rather a problem with your brakes.
How the Brake Pad Sensor Works
Brake pad sensors are small wires embedded within the brake pad material. As the brake pads wear down, the sensor wire eventually makes contact with the brake rotor, completing a circuit and triggering the warning light.
Why Resetting the Light is Important
Even after replacing worn brake pads, the warning light will remain on until it’s manually reset. This reset informs the car’s system that the new brake pads are installed and functioning correctly. Failure to reset can lead to unnecessary worry and potential misdiagnosis of future brake issues.
