Brake Pad Wear Sensor. 
The OE Match Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor the condition of the brake pads and provide an early warning when they have reached their minimum service thickness. Manufactured to OE specifications for fit, performance and reliability, this sensor helps ensure brake maintenance is carried out before braking performance is compromised.  

Fits:

• Porsche 928S2 4.7L 1984-86
• Porsche 928S4 5.0L 1987-92 

Fitted directly into the brake pad assembly, the wear sensor forms part of the vehicle's brake monitoring system and communicates with the dashboard warning circuit. When the brake pad friction material wears to a predetermined level, the sensor activates the brake wear warning indicator, alerting the driver that replacement brake pads are required.  

What This Product Does:

• Monitors brake pad wear during normal operation.
• Activates the brake pad wear warning light when pads reach their wear limit.
• Provides early notification of required brake maintenance.
• Helps prevent excessive brake pad wear.
• Protects brake discs from damage caused by worn-out pads.
• Supports safe and effective braking performance.
• Assists with preventative maintenance of the braking system.

Symptoms Of Wear Or Failure:

• Brake wear warning light remaining permanently illuminated.
• Intermittent brake wear warning messages.
• False wear warnings despite adequate brake pad thickness.
• No warning light 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 in the vehicle system.
• Warning light remaining active after brake pad replacement.

Why Replacement Matters:

• Brake pad wear sensors operate in a harsh environment, exposed to high temperatures, brake dust, moisture, road debris and constant vibration. As part of their design, many sensors are intended to wear alongside the brake pads and are commonly replaced during brake servicing.
• A damaged or worn sensor can provide inaccurate information regarding brake pad condition. This may result in unnecessary warning lights or, more critically, failure to alert the driver when brake pads require replacement. If brake pads are allowed to wear beyond their service limit, brake discs can become damaged, increasing repair costs and reducing braking effectiveness.
• Replacing a worn brake pad wear sensor restores accurate brake monitoring functionality, ensures the warning system operates correctly 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 whenever brake pads are replaced.
