Rear Brake Pad Wear Sensor - Sold each
Maintain the safety, reliability and performance of your
Porsche braking system with this OE Match Rear Brake Pad Wear Sensor. Designed specifically for Porsche 997 Carrera 2S and Carrera 4S
models, this sensor forms a vital part of the factory brake wear monitoring
system, helping drivers monitor rear brake pad condition and schedule
maintenance before braking performance is affected.
Fits:
Installed directly into the rear brake pad assembly, the wear sensor monitors the remaining thickness of the brake pad friction material. When the pads approach their minimum service limit, the sensor activates the dashboard brake wear warning light, alerting the driver that replacement is required.
For high-performance sports cars such as the Porsche 997 Carrera S models, maintaining the brake wear monitoring system is essential for preserving braking efficiency, protecting expensive brake components and ensuring maximum driving confidence.
What Does a Brake Pad Wear Sensor Do?
The brake pad wear sensor continuously monitors brake pad thickness throughout its service life.
As the brake friction material wears down, the sensor eventually contacts the brake disc and completes an electrical circuit, triggering the brake wear warning light on the instrument cluster.
A correctly functioning sensor helps:
- Monitor brake pad condition
- Provide early brake wear warnings
- Prevent excessive brake pad wear
- Protect brake discs from damage
- Improve maintenance scheduling
- Support safe braking performance
- Maintain factory brake monitoring functionality
The sensor acts as an important preventative maintenance component, helping avoid costly brake repairs.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are exposed to extreme operating conditions including heat, vibration, moisture and road contamination.
Common causes of failure include:
- Normal brake pad wear
- Sensor activation when brake pads reach their wear limit
- Damaged wiring
- Corrosion in electrical connectors
- Heat-related deterioration
- Water ingress
- Physical damage during brake servicing
- Age-related material fatigue
As brake wear sensors are considered service items, they should be replaced whenever they become activated or damaged.
When Should a Brake Pad Wear Sensor Be Replaced?
Replacement is recommended whenever brake pads are changed or if the sensor has become damaged.
Common symptoms include:
- Brake wear warning light illuminated
- Intermittent brake warning messages
- Damaged or broken sensor wiring
- False brake wear warnings
- Corroded electrical connections
- Sensor damage during brake servicing
- Rear brake pad replacement due to wear
Replacing the sensor during brake pad replacement ensures the monitoring system continues to function correctly.
Why Replacement Matters
A functioning brake wear sensor helps maintain braking safety and protects expensive brake system components.
Benefits include:
- Accurate brake pad monitoring
- Reliable dashboard warning operation
- Improved braking safety
- Protection of brake discs
- Reduced maintenance costs
- Better servicing planning
- Improved brake system reliability
- Long-term braking component protection
For Porsche 997 owners, maintaining the brake wear monitoring system helps preserve both performance and peace of mind.

Front Brake Pad Wear Sensor
Sold each - 2 required per car
Maintain the safety and effectiveness of your Porsche
braking system with this OE Match Front Brake Pad Wear Sensor, commonly
referred to as the brake pad warning wire, for the Porsche 997 Carrera 4S. This
important component continuously monitors brake pad wear and alerts the driver
when the pads have reached their service limit.
Porsche 997 MK1 Carrera 4S 3.8L 2005-08
Porsche 997 MKII Carrera C4S 3.8L 2009-12
Installed directly into the brake pad, the wear sensor forms part of the vehicle's brake monitoring system. As the brake pads wear down, the sensor eventually contacts the brake disc, breaking the electrical circuit and triggering the brake pad warning light on the dashboard. This provides a clear indication that the brake pads require replacement.
Manufactured to OE Match standards, this replacement sensor offers reliable performance, correct fitment and dependable brake wear monitoring.
What Does the Brake Pad Wear Sensor Do?
The brake pad wear sensor is designed to monitor the thickness of the brake pads.
Its primary functions include:
- Monitoring brake pad wear
- Activating the dashboard warning light
- Alerting the driver to required brake maintenance
- Supporting safe vehicle operation
- Preventing excessive brake pad wear
- Helping protect brake discs from damage
- Supporting routine brake servicing
The sensor acts as an early warning system, helping drivers replace brake pads before braking performance is compromised.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors operate in a demanding environment exposed to heat, moisture, dirt and vibration.
Common causes of failure include:
- Normal brake pad wear
- Sensor activation after pad wear
- Heat damage
- Road debris impact
- Corrosion within electrical connections
- Wiring damage
- Brake servicing damage
- Age-related deterioration
In many cases, the sensor is designed as a service item and is typically replaced whenever the brake pads are renewed.
When Should the Brake Pad Wear Sensor Be Replaced?
Replacement is recommended whenever:
- The brake wear warning light is illuminated
- New brake pads are installed
- The sensor has contacted the brake disc
- The wiring is damaged
- Corrosion is present
- Brake servicing is being carried out
- Fault codes indicate sensor failure
- Preventative maintenance is being performed
Most Porsche technicians recommend fitting new sensors whenever new brake pads are installed.
Why Replacement Matters
A damaged or worn sensor can prevent the brake monitoring system from operating correctly.
Benefits of replacement include:
- Accurate brake wear monitoring
- Reliable warning light operation
- Improved vehicle safety
- Protection against excessive pad wear
- Prevention of brake disc damage
- Correct brake system functionality
- Reduced maintenance risks
- Restoration of factory brake monitoring performance
Replacing a worn sensor is a simple and cost-effective way to maintain the effectiveness of the Porsche brake warning system.
