Brake pad wear sensor. Porsche 928 1978 ❭ 92861231303
- Porsche 928 4.5L 1978-82
Maintain the reliability of your Porsche's brake wear monitoring system with this OE Match Rear Brake Pad Wear Sensor. Produced to OE-style specifications, this rear brake pad wear sensor is designed to accurately monitor the condition of the rear brake pads and activate the dashboard warning light when the friction material reaches its service limit. Manufactured from high-quality, heat-resistant materials with durable insulated wiring and precision electrical connectors, it provides dependable performance, an accurate fit, and long service life for Porsche maintenance, repairs, and restoration projects.

Fits:
- Porsche 928 4.5L 1978 - upto chassis number 92881 01800
The rear brake pad wear sensor forms an integral part of the vehicle's braking safety system by providing an early warning when brake pad replacement is required. As the brake pads wear, the sensor contacts the brake disc, completing the warning circuit and alerting the driver. During brake servicing, the sensor should always be inspected and replaced if worn, damaged, or activated to maintain the accuracy of the brake wear monitoring system.
What This Product Does:
- Monitors the wear level of the rear brake pads.
- Activates the dashboard brake wear warning when pads reach their service limit.
- Helps prevent excessive brake pad wear.
- Supports safe and timely brake maintenance.
- Provides reliable electrical communication with the vehicle's warning system.
- Replaces worn, damaged, or activated brake pad wear sensors.
- Provides an OE-style fit for straightforward installation.
Symptoms Of Wear Or Failure:
- Rear brake pad wear warning light remaining illuminated.
- Brake wear warning failing to operate correctly.
- Damaged, broken, or frayed sensor wiring.
- Worn or activated brake pad wear sensor during brake servicing.
- Corrosion affecting the electrical connector.
- Physical damage sustained during brake pad replacement.
- Intermittent brake wear warning faults.
Why Replacement Matters:
- The rear brake pad wear sensor is an important safety component that continuously monitors rear brake pad condition and alerts the driver when replacement is required. A damaged or previously activated sensor may provide inaccurate information, resulting in false warning messages or failure to indicate excessive brake pad wear, potentially leading to unnecessary brake disc damage and reduced braking performance.
- Replacing the brake pad wear sensor whenever new rear brake pads are installed helps maintain the accuracy of the brake wear monitoring system and ensures timely brake servicing. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Rear Brake Pad Wear Sensor provides reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.

Brake pad wear sensors are designed to sense when brake pads reach a critical wear point. When the friction material becomes thin enough, the sensor’s circuit is completed (or broken) and the vehicle’s instrument cluster triggers a brake pad warning light. This alerts the driver that pad replacement is due, helping prevent rotor damage and preserve safe braking performance.
Functions & Technical Role
• Wear detection: Monitors pad thickness and detects end-of-life condition for brake pads.
• Driver alert: Interfaces with the onboard brake electronics to trigger a dashboard pad wear warning.
• Braking safety support: Helps ensure brakes are serviced before performance is compromised.
• OEM quality and fit: Manufactured to original Porsche dimensions, connectors and electrical specifications for seamless integration with brake wiring harnesses.
Brake pad wear sensors play an important safety and maintenance role. Without a functioning sensor, the vehicle cannot warn the driver when pads are worn to a critical level, increasing the risk of brake performance degradation, rotor damage, and potentially unsafe stopping distances. Replacing worn or damaged sensors with Porsche Genuine OE parts ensures the brake wear monitoring system functions exactly as designed
