Ideal for brake pad replacement, warning light repair or restoring accurate brake wear monitoring using Genuine Porsche parts.

What This Part Does / Functions
• Monitors brake pad wear
• Triggers the brake pad warning light when pads reach the service limit
• Helps alert the driver before brake pads become excessively worn
• Supports safe brake maintenance and timely pad replacement
• 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.

Why Replace This Part?
Brake pad wear sensors operate in a harsh environment and are exposed to heat, brake dust, moisture, road debris and vibration. In many applications, the sensor is designed to wear with the brake pad and should be replaced when new brake pads are fitted. A damaged or worn sensor may trigger a false warning light, fail to alert the driver when pads are worn, or become brittle and break during brake servicing. Replacing it with an OE Genuine Porsche brake pad wear sensor helps restore accurate brake wear monitoring and factory-style fitment.

Common Symptoms of a Faulty Brake Pad Wear Sensor
•  Brake pad warning light illuminated
•  Warning light remains on after pad replacement
•  Broken, brittle or damaged sensor wire
•  Sensor worn through by brake pad contact
•  Corroded or damaged connector
•  False brake wear warning
•  No warning despite heavily worn brake pads
•  Sensor damaged during brake pad removal.

When to Replace This Part
•  When replacing 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 in securely
•  During brake caliper or brake disc service
•  During brake system restoration
•  When fitting new pads and restoring correct 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 listed for front brake pad wear sensor applications on selected Porsche 911, 930 and 944 models. Correct routing is important to prevent the wire from rubbing against the wheel, brake disc or suspension components.
