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.

Brake pad wear sensor monitors pad thickness and alerts the driver when the brake pads have reached a wear limit, ensuring timely replacement and maintaining braking performance. Manufactured to OE specification, this sensor features the correct connector, cable length, mounting clip and resistance values, making it a reliable replacement for Porsche’s factory part.
• Position on Vehicle: Located at the brake caliper or backing plate where it detects the pad wear through contact or cable resistance change.
• Applications: Ideal when the original wear-sensor is damaged, disconnected, corroded, or when replacing brake pads and you wish to restore full safety and original monitoring function.
The brake pad wear sensor is an integral part of modern braking systems: it notifies the driver when pad material is low, ensuring timely servicing and helping avoid damage to rotors or calipers. A failed or missing sensor can lead to unnoticed pad wear, reduced braking efficiency and potential safety hazard. Replacing it ensures consistent pad life tracking and supports safe vehicle operation.
When and why to replace:
• Original sensor unplugged, broken or corroded
• Brake pads replaced without reinstalling a proper sensor
• Warning light for brake pad wear is triggered or malfunctioning
• Restoring a vehicle to original specification including all safety monitoring components
