Rear Brake Pad Wear Sensor for Porsche Cayenne

Global Parts 1815879 is a direct replacement disc brake pad wear sensor for select Porsche Cayenne rear applications with a black painted caliper. It monitors brake pad thickness and sends a wear alert when the pads thin out, helping you address brake service before braking performance is affected.

Key Features

• Direct replacement brake wear sensor for rear brake applications
• Blade terminal design with an oval female connector
• 1-wire harness with 2 terminal connections
• Male terminal / female connector configuration for proper fitment
• Wiring harness included for a cleaner service replacement
• Built for accurate brake pad wear detection on Porsche Cayenne rear brakes

Detailed Description

Part number 1815879 is engineered for rear brake wear monitoring on the 2019 and 2022 Porsche Cayenne with black painted calipers. As a brake pad wear sensor, it tracks pad thinning and triggers the warning system when service is due, helping maintain consistent brake system monitoring. This Global Parts sensor is a practical OE-style replacement for drivers replacing a worn or damaged rear wear sensor on a Porsche Cayenne.
