This original Porsche brake pad wear sensor, also known as a sender wire or pad wear indicator, forms part of the brake monitoring system and helps alert the driver when the brake pads have reached their service limit.
What This Part Does / Functions
• Monitors brake pad wear
• Activates the brake pad warning system when the pads reach their wear limit
• Helps alert the driver before the brake pads become excessively worn
• Supports safe and timely brake maintenance
• Connects into the vehicle’s brake wear monitoring circuit
• Replaces a worn, damaged, broken or previously triggered sensor
• Provides correct OE Porsche fitment and connector style
• Helps restore correct brake pad warning system operation after brake service.
Why Replace This Part?
Brake pad wear sensors are exposed to heat, brake dust, water, road debris and vibration. In many cases, the sensor is designed to wear with the brake pad and should be replaced whenever new brake pads are fitted. A damaged or worn sensor may trigger a warning light, fail to alert the driver when the pads are worn, or break during brake pad replacement.
Replacing it with a Genuine Porsche OE brake pad wear sensor helps maintain accurate brake wear monitoring and correct factory fitment.
Common Symptoms of a Faulty Brake Pad Wear Sensor
• Brake pad warning light illuminated
• Warning light remains on after pad replacement
• Broken or brittle sensor wire
• Sensor worn through by brake pad contact
• Corroded or damaged connector
• False brake wear warning
• No warning despite worn brake pads
• Sensor damaged during brake service.
When to Replace This Part
• When replacing rear brake pads
• If the brake pad warning light is active
• If the sensor has contacted the brake disc
• If the sensor wire is damaged, cut, brittle or broken
• If the connector is corroded or no longer clips securely
• During rear brake caliper or brake disc service
• During brake system restoration
• When fitting new pads and restoring correct brake wear monitoring
Where It Fits on the Car
This sensor fits into the brake pad wear sensor slot on the relevant brake pad and connects to the vehicle’s brake wear warning wiring. It is commonly used at the rear caliper position on selected Porsche 987 Boxster and 987 Cayman models.
Correct routing is important to prevent the wire from rubbing against the wheel, brake disc or suspension components.

The brake pad wear sensor fits into the front brake pad assembly and monitors pad wear. When the pad material wears down to the sensor contact point, the system can trigger a dashboard warning, indicating that front brake pad replacement is required.
Functions
• Replaces the front brake pad wear sensor
• Monitors front brake pad wear condition
• Helps trigger the brake pad warning system
• Supports safe and timely brake pad replacement
• Used during front brake pad or front brake system service
• Replaces worn, damaged, broken, brittle, or previously triggered sensors
• OE Match replacement for Porsche 9YA Cayenne brake maintenance.
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 front sensor during brake pad replacement helps restore the warning system and prevents false or missing brake wear alerts.
When to Replace This Part
• Front brake pads are being replaced
• The brake pad wear warning light is illuminated
• The sensor has been triggered by worn front brake pads
• The sensor wire is damaged, broken, brittle, or corroded
• Front brake warning faults are being diagnosed
• The sensor was damaged during brake service
• The vehicle is undergoing Porsche Cayenne brake system maintenance.
Where it fits on the car
This sensor fits within the front brake pad wear monitoring system on Porsche 9YA Cayenne models. Exact position can vary depending on model year, front brake caliper type, and brake pad specification.
