The sensor is fitted at the brake pad and connected to the vehicle's electrical system. As the friction material wears down, the sensor eventually reaches the brake disc. This changes the sensor circuit and triggers a brake pad wear warning, alerting the driver that the pads require inspection and replacement.

Because a wear sensor can be physically worn through when activated, it will normally need to be replaced along with the brake pads once the warning threshold has been reached. Sensors can also become damaged during brake servicing or through deterioration of their wiring and connectors.

Using the correct Porsche 95B907637F Rear Brake Pad Wear Sensor helps maintain the functionality of the factory brake wear warning system and ensures the vehicle can accurately alert the driver when rear brake pad replacement is required.

What This Product Does:

• Monitors the wear condition of the rear brake pads.
• Provides an electrical signal to the vehicle's brake monitoring system.
• Helps trigger a warning when brake pads reach their specified wear threshold.
• Alerts the driver that brake inspection and servicing are required.
• Helps prevent brake pads being unknowingly used beyond their intended service limit.
• Connects the brake pad assembly to the vehicle's monitoring circuit.
• Supports correct operation of the factory brake wear warning system.
• Replaces a worn-through, damaged or defective sensor.
• Helps clear the brake wear warning once the brakes are correctly serviced, subject to the vehicle's reset procedure.
• Provides the correct Porsche replacement part for compatible applications.  

Symptoms Of Wear Or Failure:

• Brake pad wear warning displayed on the dashboard.
• Brake service warning remaining illuminated after new pads are fitted.
• Sensor tip visibly worn through. Damaged or broken sensor wiring.
• Cracked or deteriorated insulation. Damaged electrical connector.
• Wiring pulled away from its mounting points. Intermittent brake wear warning.
• Warning appearing despite adequate brake pad thickness.
• Sensor damaged during brake pad or disc replacement.
• Corrosion or contamination affecting the electrical connection.
• Diagnostic testing indicating a fault in the brake pad wear sensor circuit.  

Why Replacement Matters:

• The brake pad wear sensor provides an important early warning that the friction material is approaching its service limit. If the sensor is damaged or bypassed, the driver may lose this warning function.
• Continuing to drive after brake pads are excessively worn can eventually allow the pad backing material to contact the brake disc. This can significantly reduce braking performance and damage the discs, increasing the extent and cost of the required repair.
• Once a wear sensor has contacted the brake disc and activated the warning, the sensor itself may be physically worn and cannot simply be reused with new pads. Installing a replacement sensor during the brake service restores the monitoring circuit for the new brake pads.
• Damaged wiring can also produce persistent or intermittent dashboard warnings even when the pads are in good condition.
• Replacing a worn or defective sensor with the correct Porsche Rear Brake Pad Wear Sensor 95B907637F helps restore reliable brake wear monitoring and ensures the vehicle can provide the intended warning when future brake service becomes necessary.
