This genuine Porsche brake pad wear sensor signals the brake system when the front brake pads are approaching their wear limits and need replacement.

Originally numbered 99160918180, this part now carries the updated Porsche reference 9GT907637 but remains identical in fit, function, and OE authenticity. It integrates with the vehicle’s ABS and braking system electronics to provide timely alerts and support safe operation.

The wear sensor continuously monitors brake pad thickness and electrical continuity. When the pad material reaches a specified minimum level, the sensor triggers a warning in the driver information system to indicate that pad replacement is due - helping you avoid excessive wear or potential damage to discs.

Function:
•  Detects brake pad wear on the front axle
•  Sends timely alerts to the vehicle’s onboard diagnostic system
•  Helps prevent brake pad and disc damage due to overdue replacement
•  Genuine OE Porsche design ensures perfect electrical integration
•  Factory-tested for consistent performance and longevity.

Brake pads naturally wear over time, and monitoring their condition is critical for safe, reliable braking performance. A worn or missing wear sensor can lead to pad wear going undetected, increasing the risk of rotor damage and compromised stopping power. Replacing the wear sensor with a genuine Porsche OE part ensures accurate detection and maintains compliance with factory safety systems.

When to replace:
•  Brake wear warning light activates on the dashboard
•  After installing new brake pads If the sensor is damaged or broken
•  During front brake servicing or rotor replacement
•  When replacing brake calipers with integrated sensors
