Description
- Pad Wear Sensor: This is a common type of VW brake sensor that monitors the life of your brake pads.
-
Function: As brake pads wear down due to friction during braking, a thin metal contact eventually gets exposed. This contact rubs against the brake disc, creating a circuit and sending a signal to the car’s computer.
-
Warning: When the VW computer detects this signal, it triggers a warning light on the dashboard, typically an indicator light or message about needing a brake pad replacement. This is a crucial reminder to get your brakes checked and the pads replaced before they wear down completely and compromise your braking performance.
