Brake Pad Wear Sensor - Front
Sold each - 2 required per car
Maintain the safety and reliability of your Porsche braking
system with this OE Match Brake Pad Wear Sensor, designed for
Porsche 928 models produced between 1978 and 1985. This sensor forms part of
the factory brake wear monitoring system, providing an early warning when brake
pads approach their service limit.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
The brake pad wear sensor is installed within the brake pad and is designed to trigger a warning light when the friction material wears to a predetermined level. This allows drivers to replace brake pads before braking performance is compromised or damage occurs to the brake discs.
For a high-performance grand touring car such as the Porsche 928, maintaining the braking system in optimum condition is essential for both safety and driving enjoyment.
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 contacts the brake disc and completes an electrical circuit that activates the brake wear warning light on the dashboard.
A correctly functioning sensor helps:
- Monitor brake pad condition
- Provide early wear warnings
- Prevent excessive brake pad wear
- Protect brake discs from damage
- Improve maintenance planning
- Enhance braking safety
- Support reliable vehicle operation
The sensor acts as an important safeguard, helping owners identify when brake service is required.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors operate in a harsh environment exposed to heat, moisture, road debris and vibration.
Common causes of failure include:
- Normal brake pad wear
- Sensor activation during pad wear
- Damaged sensor wiring
- Corrosion in electrical connections
- Heat-related deterioration
- Physical damage during brake servicing
- Water and dirt contamination
- Age-related material fatigue
In many cases, the sensor is designed as a service item and should be replaced whenever it has been triggered or damaged.
When Should a Brake Pad Wear Sensor Be Replaced?
Brake wear sensors should typically be replaced during brake pad replacement or whenever a fault is identified.
Common symptoms include:
- Brake wear warning light illuminated
- Intermittent brake warning messages
- Damaged or broken sensor wiring
- False brake wear warnings
- Sensor damage during brake servicing
- Corrosion around the sensor connection
- Brake pads being replaced due to wear
Replacing the sensor when fitting new brake pads helps ensure the monitoring system continues to operate correctly.
Why Replacement Matters
A functioning brake pad wear sensor provides an important warning system that helps protect both the braking system and vehicle occupants.
Benefits include:
- Accurate brake wear monitoring
- Improved vehicle safety
- Reduced risk of brake damage
- Early maintenance alerts
- Protection of expensive brake discs
- Reliable dashboard warning operation
- Improved servicing accuracy
- Long-term braking system reliability
For Porsche 928 owners, maintaining the brake wear monitoring system helps preserve the safety and performance expected from a Porsche grand tourer.

The OE Match Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor brake pad wear and alert the driver when the brake pads have reached their service limit. Manufactured to OE specifications for fit, function and reliability, this sensor forms an important part of the vehicle's brake wear monitoring system.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
Installed directly into the brake pad assembly, the sensor provides an electrical signal to the vehicle's dashboard warning system when the brake friction material becomes excessively worn. This helps ensure brake maintenance is carried out at the correct interval, protecting both braking performance and associated braking components.
What This Product Does:
- Monitors brake pad wear levels.
- Triggers the brake pad wear warning light when pads reach their service limit.
- 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.
- Provides early warning of required brake servicing.
Symptoms Of Wear Or Failure:
- Brake pad wear warning light remaining illuminated.
- Intermittent brake wear warning messages.
- False brake wear warnings despite adequate pad thickness.
- No brake wear warning when pads are excessively worn.
- Damaged, broken or corroded sensor wiring.
- Physical damage to the sensor body.
- Electrical fault codes related to the brake wear monitoring system.
- Warning lights remaining active after brake pad replacement.
Why Replacement Matters:
- Brake pad wear sensors are exposed to heat, moisture, road debris, brake dust and constant vibration. During normal operation, the sensor is designed to wear alongside the brake pads and often requires replacement when new brake pads are installed.
- A faulty or damaged sensor can provide inaccurate wear readings, potentially leading to unnecessary warning lights or, more importantly, failure to alert the driver when brake pads require replacement. This can result in excessive brake pad wear, brake disc damage and reduced braking efficiency.
- Replacing a worn or damaged brake pad wear sensor ensures accurate brake wear monitoring, restores proper warning system functionality 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.
