Product Information
Brake Pad Wear Sensor. 
The OE Match Brake Pad Wear Sensor is a high-quality replacement braking system component designed to continuously monitor brake pad condition and provide a warning when the friction material reaches its minimum safe thickness. Manufactured to OE specifications for fit, function and reliability, this sensor helps ensure timely brake maintenance and supports safe vehicle operation.

Fits:
  • Porsche 928 4.5L 1978-82

Installed directly into the brake pad assembly, the wear sensor forms part of the vehicle's brake monitoring system. When the brake pads wear down to a predetermined level, the sensor triggers the dashboard brake wear warning light, notifying the driver that brake pad replacement is required.  

What This Product Does:
  • Monitors brake pad wear throughout the service life of the pads.
  • Activates the brake pad wear warning indicator when replacement is required.
  • Helps prevent excessive brake pad wear.
  • Protects brake discs from damage caused by worn friction material.
  • Supports safe and effective braking performance.
  • Assists with preventative brake maintenance.
  • Provides early warning of brake service requirements.

Symptoms Of Wear Or Failure:
  • Brake wear warning light remaining illuminated.
  • Intermittent brake pad warning messages.
  • False brake wear warnings despite healthy brake pads.
  • No warning light when brake pads are excessively worn.
  • Damaged, broken or corroded sensor wiring.
  • Physical damage to the sensor body.
  • Fault codes relating to the brake wear monitoring system.
  • Warning light remaining active after brake pad replacement.

Why Replacement Matters:

  • Brake pad wear sensors operate in demanding conditions and are constantly exposed to heat, brake dust, moisture, road debris and vibration. In many applications, the sensor is designed to wear alongside the brake pads and should be replaced during brake servicing to ensure continued monitoring accuracy.
  • A damaged or worn sensor can provide inaccurate brake wear information, potentially resulting in unnecessary warning lights or failure to alert the driver when brake pads have reached their service limit. If brake pads are allowed to wear excessively, braking performance can be reduced and costly damage to the brake discs may occur.
  • Replacing a worn brake pad wear sensor restores accurate brake wear monitoring, ensures proper operation of the 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 maintenance and pad replacement.

Perfectly matched to your vehicle’s braking system, the wear sensor offers an accurate fit and dependable signal transmission, providing real-time feedback to your dashboard warning system.

What It Does
The brake pad wear sensor works by detecting the gradual thinning of your brake pads. When the friction material reaches a predetermined level, the sensor wire completes an electrical circuit, triggering a warning light on the dashboard.

Key Features and Benefits:

  • Accurate Wear Detection: Alerts you before the pads reach unsafe levels.
  • Precision Fitment: Designed to integrate seamlessly into your vehicle’s braking system.
  • High Durability: Built with heat-resistant materials for longevity under high-stress conditions.
  • Reliable Signal Transmission: Ensures consistent performance in all driving environments.
  • Easy Installation: Direct-fit replacement with no modification required. 
  • Compatible with Advanced Braking Systems: Suitable for vehicles equipped with electronic wear monitoring.

This ensures you always know the exact status of your brake pads, helping prevent unnecessary damage to discs or reduced braking performance.

Why Brake Pad Wear Sensors Fail
Even with robust materials, brake pad wear sensors are exposed to heat, friction dust, and debris that can degrade their effectiveness over time.

Common Causes of Failure:

  • Heat Damage: Prolonged exposure to high brake temperatures melts or cracks the sensor wire insulation.
  • Corrosion or Moisture Ingress: Causes false readings or loss of signal.
  • Physical Damage: Pinching or abrasion from improper installation or road debris.
  • Connector Wear: Loose or corroded connectors lead to intermittent warnings.
  • Old Age: Sensor wires can become brittle over time, reducing reliability.

When a sensor fails, your dashboard warning system may trigger false alerts — or worse, fail to warn you when pads are truly worn out.

Why They Should Be Replaced
Replacing your worn or damaged brake pad wear sensor is vital to maintaining accurate monitoring and safe braking performance.

Benefits of Replacing 

  • Accurate Wear Alerts: Receive timely dashboard warnings to prevent brake damage.
  • Improved Safety: Ensure optimal braking response and shorter stopping distances.
  • Protects Brake Components: Prevents unnecessary wear on discs and calipers.
  • Restores Dashboard Functionality: Clears false error lights and warning codes.
  • Long-Term Reliability: Made from heat- and corrosion-resistant materials.
  • Direct Replacement: Designed for plug-and-play installation — no rewiring required.

This sensor is the perfect upgrade for drivers who value precision, reliability, and peace of mind.
