As the brake pads wear, the sensor is designed to contact the brake disc at a predetermined thickness, completing or breaking an electrical circuit to trigger the dashboard warning. Once activated or physically worn, the sensor should normally be replaced during brake pad replacement.
• A damaged or failed sensor can provide inaccurate wear information, potentially allowing brake pads to wear beyond their safe operating limit or triggering unnecessary warning messages. Excessively worn brake pads can damage the brake discs, increasing repair costs and compromising braking performance.
• Replacing the brake pad wear sensor during brake servicing restores accurate brake wear monitoring and ensures the braking system continues to provide reliable maintenance alerts. An OE Match replacement offers factory-style fitment, dependable electronic performance and long-lasting durability, helping maintain the safety and reliability expected from your Porsche.
