Front Brake Pad Wear Sensor
Sold each - 2 required per car
Maintain the safety and performance of your Porsche braking
system with this OE Match Front Brake Pad Wear Sensor 92861236601, designed
specifically for Porsche 928 models produced between 1992 and 1995. This sensor
forms an important part of the factory brake monitoring system, providing an
early warning when the front brake pads have reached their minimum service
thickness.
Fits:
- Porsche 928GTS 5.4L 1992-95
Installed directly into the brake pad assembly, the sensor monitors brake pad wear and activates the dashboard brake warning light when replacement is required. This simple but essential component helps prevent excessive brake wear, protects expensive brake discs and ensures the braking system continues to perform at its best.
For high-performance grand touring models such as the later Porsche 928 S4, GT and GTS, maintaining the brake wear monitoring system is essential for both safety and reliability.
What Does a Brake Pad Wear Sensor Do?
The brake pad wear sensor continuously monitors the thickness of the brake pad friction material.
As the brake pad wears down, the sensor eventually makes contact with the brake disc and triggers the brake wear warning circuit, alerting the driver that replacement is required.
A correctly functioning sensor helps:
- Monitor brake pad condition
- Provide early brake wear warnings
- Protect brake discs from damage
- Improve maintenance scheduling
- Support safe braking performance
- Reduce unexpected repair costs
- Maintain factory brake monitoring functionality
The sensor provides valuable advance notice before brake performance is affected.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors operate in a demanding environment exposed to heat, vibration, moisture and road debris.
Common causes of failure include:
- Normal brake pad wear
- Sensor activation due to worn pads
- Damaged sensor wiring
- Corrosion within electrical connections
- Heat-related deterioration
- Physical damage during brake servicing
- Water or dirt contamination
- Age-related component degradation
Because the sensor is designed to function alongside the brake pads, replacement is typically recommended whenever new brake pads are fitted.
When Should a Brake Pad Wear Sensor Be Replaced?
The sensor should be replaced whenever it has been activated, damaged or when new brake pads are installed.
Common symptoms include:
- Brake wear warning light illuminated
- Intermittent brake warning indications
- Damaged or broken wiring
- False brake wear alerts
- Corroded electrical connections
- Sensor damage during brake servicing
- Brake pad replacement due to wear
Replacing the sensor at the same time as the brake pads helps ensure the brake monitoring system remains fully functional.
Why Replacement Matters
A functioning brake pad wear sensor helps maintain braking safety and reduces the risk of costly brake system repairs.
Benefits include:
- Accurate brake wear monitoring
- Reliable warning light operation
- Improved vehicle safety
- Protection of brake discs
- Reduced maintenance costs
- Better servicing accuracy
- Enhanced braking system reliability
- Long-term brake system protection
For Porsche 928 owners, maintaining the factory brake wear warning system helps preserve both driving confidence and vehicle safety.

These OE direct-fit brake wear sensor integrates seamlessly with your Porsche's electronic braking system, ensuring accurate wear monitoring and helping prevent unnecessary brake disc damage caused by excessively worn brake pads.
What Does the Brake Pad Wear Sensor Do?
The brake pad wear sensor is an important safety component that monitors the thickness of the front brake pads. As the friction material wears down, the sensor eventually contacts the brake disc, completing an electrical circuit that activates the brake wear warning light on the dashboard.
Its primary functions include:
- Monitoring front brake pad wear.
- Activating the dashboard brake warning light.
- Preventing excessive brake pad wear.
- Helping protect the brake discs from damage.
- Supporting scheduled brake maintenance.
- Improving overall braking safety.
The sensor provides an early warning, allowing brake pads to be replaced before braking performance is compromised.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are consumable components and are
designed to be replaced during brake servicing. Common reasons for failure
include:
- Normal activation once the brake pads reach their wear limit.
- Heat generated by the braking system.
- Damage during brake pad removal.
- Road debris and moisture.
- Corrosion of the electrical contacts.
- Wiring damage caused by age or movement.
- General wear after years of service.
Once activated, the sensor cannot normally be reused and should always be replaced with new brake pads.
When Should the Brake Pad Wear Sensor Be Replaced?
Replacement is recommended whenever:
- The brake wear warning light is illuminated.
- New front brake pads are installed.
- The sensor has contacted the brake disc.
- The wiring has become damaged.
- Corrosion affects the electrical connector.
- During routine brake servicing.
- As part of a complete front brake overhaul.
Replacing the sensor at the same time as the brake pads ensures accurate future wear monitoring and avoids unnecessary labour costs.
