Information
Brake Pad Wear Sensor.
The OE Match Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor brake pad wear and provide a timely warning when the brake pads approach their minimum safe thickness. Manufactured to OE specifications for fit, reliability and performance, this sensor is an essential part of the vehicle's brake wear monitoring system.
Fits:
Installed directly into the brake pad assembly, the sensor continuously monitors the condition of the brake friction material. When the pads wear to a predetermined limit, the sensor activates the dashboard brake wear warning light, alerting the driver that brake service is required. This helps maintain optimum braking performance and prevents unnecessary damage to other brake system components.

- Porsche 944S 2.5L 16V 1987-88
Installed directly into the brake pad assembly, the sensor continuously monitors the condition of the brake friction material. When the pads wear to a predetermined limit, the sensor activates the dashboard brake wear warning light, alerting the driver that brake service is required. This helps maintain optimum braking performance and prevents unnecessary damage to other brake system components.
What This Product Does:
- Monitors brake pad wear throughout the life of the brake pads.
- Activates the brake wear warning light when replacement is required.
- Provides early notification of brake maintenance needs.
- Helps prevent excessive brake pad wear.
- Protects brake discs from damage caused by worn brake pads.
- Supports safe and effective braking performance.
- Assists with preventative brake system maintenance.
Symptoms Of Wear Or Failure:
- Brake wear warning light remaining permanently illuminated.
- Intermittent brake wear warning messages.
- False brake wear alerts despite sufficient brake pad thickness.
- No warning indication when brake pads are excessively worn.
- Damaged, frayed or broken sensor wiring.
- Corrosion or physical damage to the sensor body.
- Brake monitoring fault codes stored within the vehicle system.
- Warning light remaining active after brake pad replacement.
Why Replacement Matters:
- Brake pad wear sensors operate in a harsh environment and are exposed to brake dust, heat, moisture, road debris and constant vibration. In many applications, the sensor is designed to wear alongside the brake pads and should be replaced whenever new brake pads are installed to maintain accurate monitoring.
- A damaged or malfunctioning sensor can provide inaccurate wear information, potentially leading to unnecessary warning lights or failure to notify the driver when brake pads require replacement. If brake pads wear beyond their safe operating limit, braking performance may be reduced and costly damage to the brake discs can occur.
- Replacing a worn brake pad wear sensor restores accurate brake wear monitoring, ensures correct operation of the dashboard warning system and helps maintain safe braking performance. An OE Match replacement provides factory-style fitment, dependable operation and long-term reliability, making it an essential component during brake servicing and maintenance.

Brake pad wear sensors provide an early warning when your front brake pads have reached their service limit, allowing them to be replaced before braking performance is affected or damage occurs to the brake discs.
This OE Match replacement uses a single pad sensor design, whereas the original Porsche sensor uses a double pad sensor. Despite this difference, the sensor functions exactly as intended by connecting it to one brake pad only, providing the same reliable brake wear monitoring and dashboard warning operation as the original system.
Manufactured to OE-quality standards, this direct-fit replacement offers dependable performance, excellent durability and outstanding value.
What Does a Brake Pad Wear Sensor Do?
The brake pad wear sensor is an electronic monitoring device fitted to the brake pads. As the friction material wears down, the sensor eventually contacts the brake disc, completing an electrical circuit that illuminates 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 expensive brake discs.
- Supporting scheduled vehicle maintenance.
- Improving braking safety.
The warning system gives the driver sufficient notice to replace the brake pads before braking performance is compromised.
Single Sensor Design
Unlike the original Porsche sensor, which monitors two brake pads, this OE Match version uses one single pad sensor.
This is completely normal for this replacement design and does not affect operation. Simply connect the sensor to one brake pad, where it will function exactly as intended by providing accurate brake wear indication through the factory warning system.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are designed as consumable service components and are normally replaced during every brake pad change.
Common reasons for replacement include:
- Activation after the brake pads reach their wear limit.
- Damage during brake pad removal.
- Heat generated by the braking system.
- Moisture and road contamination.
- Corrosion of the electrical contacts.
- Wiring damage caused by movement or age.
- General deterioration over time.
Once activated, a brake wear sensor should not normally be reused.
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 becomes damaged.
- Corrosion affects the electrical connector.
- During routine brake servicing.
- Completing a front brake overhaul.
Brake pad wear sensors should normally be replaced whenever replacing your brake pads to ensure accurate brake wear monitoring and reliable long-term operation.
