Why Replace This Part?
Brake pad wear sensors are designed to wear with the brake pads and may be damaged or triggered once the pads reach their wear limit. Sensors can also become brittle, corroded, broken, or damaged during brake servicing. Replacing the rear sensor during brake pad replacement helps restore the warning system and prevents false or missing brake wear alerts.
When to Replace This Part
• Rear brake pads are being replaced
• The brake pad wear warning light is illuminated
• The sensor has been triggered by worn rear brake pads
• The sensor wire is damaged, broken, brittle, or corroded
• Rear brake warning faults are being diagnosed
• The sensor was damaged during brake service
• The vehicle is undergoing Porsche Boxster or Cayman brake system restoration.
Where it fits on the car
This sensor fits within the rear brake pad wear monitoring system on Porsche 981 Boxster, 981 Cayman, 718 Boxster, and 718 Cayman models. Exact position can vary depending on model year, rear brake caliper type, and brake pad specification.
