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.

What This Product Does:

• The brake pad wear sensor is an electronic (or electrical) component mounted in the brake pad or on the pad carrier that monitors how much friction material remains on the brake pads. When the pad material wears down to a predefined depth, the sensor triggers a warning light (or message) on the instrument cluster, alerting the driver that the brake pads need replacement.
• It helps prevent brake pad material becoming too thin, which could lead to metal-to-rotor contact, rotor damage, decreased braking performance, excessive noise, or even failure of the brake system under heavy load.
• On the 911 992 (and similar models), because performance and safety are critical, ensuring the wear sensor is functioning correctly helps maintain expected braking performance, safe maintenance intervals, and protects against unexpected pad failure.

Signs & When To Replace:

• The brake pad warning light or a message displays on your dash indicating “Brake pad wear” or similar — it could signify that the sensor is triggered or faulting.
  
• You have replaced the brake pads and did not install a new sensor, or the old sensor was damaged or not re-installed — it’s best practice to replace the sensor whenever the pads are changed.
  
• The wiring to the sensor is damaged, frayed, broken, or the connector is corroded or loose. A broken sensor cable will not warn you of low pad material.
  
• You are replacing the brake pads/discs or servicing the front brakes — installing a fresh sensor ensures correct maintenance.

Why Replacement Matters:

• Brake safety and performance: The sensor is a key part of the wear-monitoring system—without it you may continue driving after the pads are too thin, risking rotor damage or reduced stopping power.
  
• Prevents unintended damage: If pads are worn too far without notice, metal backing might contact the rotor, causing rotor scoring, vibration or costly damage. The wear sensor helps prevent that scenario.
  
• Ease of inspection: With the sensor functioning, you receive timely alerts rather than relying on guesswork or manual inspection; this is especially useful in performance cars that may be driven hard.
