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.

The brake pad wear sensor harness serves as the electrical link between each brake pad wear sensor and the vehicle’s signal/monitoring circuitry (ABS/ECU). As the pads wear down to a threshold level, the sensor completes a circuit that triggers a warning light on the dash, alerting the driver that pad replacement is due.

Function: This harness routes and secures the sensor wiring safely along the suspension and chassis to avoid interference, chafing, or damage. The OE Match harness preserves correct electrical paths and protects the sensor signal from interruption - essential for accurate brake pad condition monitoring.
Brake pad wear sensor systems rely on both the sensor element and the wiring harness to deliver accurate warnings. A damaged or broken harness can interrupt the signal even with new sensors fitted, leading to false “OK” readings or no warning when pads are worn. Replacing the wiring harness with an OE Match unit ensures reliable signal transmission and correct integration with the vehicle’s monitoring systems, helping prevent brake damage or unexpected failures.
When to replace.
Replace this harness if you notice any of the following:
• Brake wear warning lamp stays off despite worn pads
• Intermittent or false pad wear warnings
• Visible frayed wiring, broken connectors, or chafing
• Previous repairs with generic wiring failed
• During brake pad or ABS sensor system servicing

High-quality OE Match replacement rear brake pad wear sensor, engineered to match original Porsche specifications for monitoring rear brake pad wear. Designed for Porsche 997 models, this sensor works with the vehicle’s onboard diagnostic system to provide timely alerts when the rear brake pads approach the service limit.
Sold individually, typically 2 sensors per axle for complete rear pad sets
Fits:
Porsche 997.2 C2 2009 - 2012 Rear Caliper
Porsche 997.2 C4 / C4S 2009 - 2012 Rear Caliper
Porsche 997 TT / GT2 2007 - 2013 Rear Caliper
Porsche 997 GT3 2007 - 2013 Rear Caliper
The rear brake pad wear sensor detects when the brake pad material has worn to its minimum safe thickness and signals the vehicle’s warning system. This alert enables brake servicing before the pads cause damage to other braking components.
Function:
• Monitors rear brake pad wear
• Interfaces with the vehicle’s onboard warning system
• Helps prevent brake rotor damage from worn pads
Brake pads naturally wear down with use. A functioning brake pad wear sensor ensures you receive timely alerts before the pads reach critically low levels. Without a reliable sensor, pad wear may go unnoticed, leading to reduced braking performance, rotor damage, and safety concerns - especially on performance-oriented vehicles like the 997.
When to replace:
• Brake wear warning light appears
• Sensor wiring or connector is damaged or corroded
• After rear brake pad replacement
• During routine brake system servicing
• When upgrading brake components
