Brake pad wear sensor. Porsche 997 C2S  ❭  997612

Brake pad wear sensor.
The purpose of a brake pad wear sensor is to monitor pad thickness. When the pad material wears to a certain point, the sensor closes a circuit or sends a signal to the vehicle's brake control module, alerting the driver to replace the pads. Built to OEM specifications, it ensures the correct connector type, length, mounting clamp interface, and resistance calibration, consistent with factory parameters. It should normally be replaced when replacing your brake pads.

• Position on Vehicle: Mounted adjacent to the front disc brake pads, typically clipped into the caliper or pad backing plate with the sensor end extending to contact the rotor or matching pad drain hole.

• Applications: Ideal when the original wear sensor has failed, is missing, or during brake pad replacement to ensure the wear-warning circuit remains intact and fully functional.

The brake pad wear sensor is a small yet essential part of your vehicle’s safety system. When it fails or is removed, your brake pad wear monitoring may become inactive - leading to unnoticed pad depletion, increased rotor wear or even unscheduled brake failure. Replacing it ensures that when your pads reach their safe limit, you’ll receive an accurate alert and can service your brakes in time.

When and why to replace:
• The brake pad wear warning light is showing, indicating the sensor circuit has been triggered or failed.
• The sensor wiring is damaged, corroded, or the sensor itself is missing or reused excessively.
• During brake pad replacement - fitting a new sensor ensures the system remains fully functional.
• After any caliper or brake overhaul where the original sensor connection might have been disturbed.
• When using non-standard or aggressive brake pads, where ensuring the warning circuit works is particularly important.
