- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
Designed as a direct replacement for the factory sensor, it provides reliable operation, precise fitment and dependable brake wear monitoring, helping to ensure your Porsche continues to deliver the braking performance expected from a high-performance SUV.
What Does the Rear Brake Pad Wear Sensor Do?
The rear brake pad wear sensor, also known as a brake pad warning wire, is fitted to the brake pad and monitors the thickness of the friction material throughout its service life.
Its primary functions include:
- Monitoring rear brake pad wear.
- Activating the dashboard brake wear warning light when replacement is required.
- Helping prevent excessive brake pad wear.
- Protecting expensive brake discs from damage.
- Supporting routine brake maintenance.
- Helping maintain safe braking performance.
This simple but essential component allows brake pads to be replaced before they become dangerously worn.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are exposed to constant heat, moisture,
dirt and vibration. Common causes of failure include:
- Normal activation once the brake pads reach their wear limit.
- Damage during brake pad replacement.
- Heat deterioration from repeated braking.
- Corrosion affecting the sensor wiring or connectors.
- Impact damage from road debris.
- Age-related deterioration of the cable insulation.
Once activated, most Porsche brake wear sensors cannot be reused and should always be replaced when new brake pads are fitted.
When Should the Rear Brake Pad Wear Sensor Be Replaced?
The brake pad wear sensor should be replaced whenever:
- New rear brake pads are installed.
- The dashboard brake wear warning light is illuminated.
- The sensor has been damaged during servicing.
- The wiring is cracked or deteriorated.
- The connector shows signs of corrosion.
- The sensor has been activated through normal brake pad wear.
Replacing the sensor during every brake service helps ensure the brake wear monitoring system continues to operate accurately and reliably.

The OE Match Rear Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor rear brake pad wear and provide a warning when the brake pads have reached their minimum safe operating thickness. Manufactured to OE specifications for fit, performance and reliability, this sensor forms an integral part of the vehicle's brake wear monitoring system.

Installed directly into the rear brake pad assembly, the sensor continuously monitors the condition of the brake friction material. Once the pads wear to a predetermined level, the sensor activates the dashboard brake wear warning light, alerting the driver that rear brake pad replacement is required. This helps maintain braking efficiency and protects other braking system components from unnecessary wear.
What This Product Does:
- Monitors rear brake pad wear throughout the life of the brake pads.
- Activates the brake wear warning light when replacement is required.
- Provides early notification of rear brake maintenance needs.
- Helps prevent excessive brake pad wear.
- Protects brake discs from damage caused by worn brake pads.
- Supports safe and effective braking performance.
- Assists with preventative brake system maintenance.
Symptoms Of Wear Or Failure:
- Rear brake wear warning light remaining illuminated.
- Intermittent brake wear warning messages.
- False brake wear alerts despite sufficient brake pad thickness.
- No warning indication when rear brake pads are excessively worn.
- Damaged, broken or frayed sensor wiring.
- Corrosion or physical damage to the sensor body.
- Brake system fault codes related to the wear monitoring circuit.
- Warning light remaining active after brake pad replacement.
Why Replacement Matters:
- Rear brake pad wear sensors operate in harsh conditions and are continually exposed to brake dust, heat, moisture, road debris and vibration. In many applications, the sensor is designed to wear alongside the brake pads and should be replaced whenever new rear brake pads are fitted to ensure continued monitoring accuracy.
- A damaged or malfunctioning sensor can provide inaccurate brake wear information, potentially leading to unnecessary warning lights or failure to alert the driver when rear brake pads require replacement. If brake pads wear beyond their service limit, braking performance may be reduced and expensive damage to the brake discs can occur.
- Replacing a worn rear brake pad wear sensor restores accurate brake monitoring, ensures proper operation of the warning system and helps maintain safe braking performance. An OE Match replacement provides factory-style fitment, dependable operation and long-term reliability, making it an essential component during rear brake servicing and maintenance.
