Front Brake Pad Wear Sensor
Sold each - 2 required per car
Maintain the safety and performance of your braking system
with this OE Match Front Brake Pad Wear Sensor, designed
specifically for Porsche 944 models produced between 1987 and 1989. This sensor
forms an important part of the factory brake monitoring system, providing an
early warning when front brake pads have reached their minimum service
thickness.
Fits:
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 2.7L 8V 1988-89
- Porsche 944S 2.5L 16V 1987-88
Installed within the front brake pad assembly, the wear sensor is designed to trigger the dashboard brake wear warning light when the friction material becomes worn. This allows owners to replace brake pads before braking efficiency is compromised or expensive brake disc damage occurs.
For a performance-focused sports car such as the Porsche 944, maintaining the braking system in peak condition is essential for both safety and driving confidence.
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, the sensor eventually contacts the brake disc and completes an electrical circuit that illuminates the brake wear warning light on the dashboard.
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 planning
- Support safe braking performance
- Maintain factory brake monitoring functionality
The sensor acts as an early warning system, helping drivers address brake wear before it becomes a safety concern.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors operate in an environment exposed to heat, moisture, road debris and vibration.
Common causes of failure include:
- Normal brake pad wear
- Sensor activation through brake pad wear
- Damaged sensor wiring
- Corrosion in electrical connections
- Heat damage
- Physical damage during brake servicing
- Water and dirt contamination
- Age-related deterioration
Because the sensor is designed to wear alongside the brake pad, replacement is often recommended whenever new brake pads are installed.
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 fitted.
Common signs include:
- Brake wear warning light illuminated
- Intermittent brake warning messages
- Damaged or broken wiring
- False brake wear warnings
- Corrosion at sensor connections
- Brake pad replacement due to wear
- Sensor damage during servicing
Replacing the sensor during brake maintenance helps ensure continued reliability of the brake monitoring system.
Why Replacement Matters
A functioning brake pad wear sensor helps maintain both safety and braking system reliability.
Benefits include:
- Accurate brake wear monitoring
- Early maintenance alerts
- Protection of brake discs
- Improved braking safety
- Reliable dashboard warning operation
- Reduced risk of excessive brake wear
- Better service planning
- Long-term braking system protection
For Porsche 944 owners, maintaining the factory brake wear warning system helps preserve both performance and peace of mind.

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
