Brake Pad Wear Sensor.
The OE Match Brake Pad Wear Sensor is a high-quality replacement braking system component designed to monitor brake pad wear and provide a warning when the brake pads reach their minimum service thickness. Manufactured to OE specifications for fit, function and reliability, this sensor helps ensure brake maintenance is carried out at the correct time, protecting both braking performance and associated brake components.

Fits:

• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>>
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10 

Installed directly into the brake pad assembly, the wear sensor continuously monitors the remaining friction material. When the brake pads wear to a predetermined limit, the sensor activates the dashboard brake wear warning light, alerting the driver that brake pad replacement is required.

What This Product Does:

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

Symptoms Of Wear Or Failure:

• Brake wear warning light remaining illuminated.
• Intermittent brake wear warning messages.
• False brake wear warnings despite adequate brake pad thickness.
• No warning light when brake pads are excessively worn.
• Damaged, broken or frayed sensor wiring.
• Corrosion or physical damage to the sensor body.
• Brake system fault codes relating to the wear monitoring circuit.
• Warning light remaining active after brake pad replacement.

Why Replacement Matters:

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

Brake Pad Wear Sensor, Front. 
The OE Match Front Brake Pad Wear Sensor is a premium-quality replacement braking system component designed to accurately monitor the condition of the front brake pads on compatible Porsche models. Manufactured to OE specifications for fit, performance and durability, this sensor provides an early warning when the brake pads have reached their service limit, allowing timely replacement to maintain optimum braking performance and vehicle safety.  



Fits:

• Porsche 957 Cayenne 3.6L 2007-08
• Porsche 957 Cayenne S / GTS 4.8L 2007-08
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-08

*Brake Caliper Painted Red*

Manufactured using high-quality heat-resistant materials with durable insulated wiring and corrosion-resistant electrical connectors, the brake pad wear sensor is engineered to withstand the extreme temperatures, brake dust, moisture and vibration associated with the front braking system. Designed for direct OE-style installation, it integrates seamlessly with the vehicle's electronic brake wear monitoring system, ensuring reliable operation and factory-correct functionality. 

What This Product Does:

• Monitors the wear level of the front brake pads.
• Sends a warning signal when the brake pads reach their service limit.
• Activates the dashboard brake pad wear warning light.
• Helps ensure brake pads are replaced at the correct service interval.
• Supports safe and consistent braking performance.
• Integrates with the vehicle's electronic brake monitoring system.
• Restores factory brake wear monitoring functionality.
• Forms an essential part of the front braking system.

Symptoms Of Wear Or Failure:

• Brake pad wear warning light remaining illuminated.
• Brake pad warning light failing to illuminate despite worn brake pads.
• Intermittent brake wear warning messages.
• Brake system fault codes relating to the wear sensor.
• Damaged or broken sensor wiring.
• Corroded or damaged electrical connector.
• Physical damage during brake servicing.
• Incorrect brake wear indication.
• Dashboard brake system warning message.
• MOT or vehicle inspection concerns relating to the braking system.

Why Replacement Matters:

• The front brake pad wear sensor operates in a harsh environment where it is exposed to high temperatures, brake dust, water, road debris and vibration. As the brake pads wear, the sensor is designed to make contact with the brake disc at a predetermined point, triggering the dashboard warning light. Once activated, or if damaged during servicing, the sensor should always be replaced.
• A faulty or damaged wear sensor can provide inaccurate brake wear information, potentially delaying essential brake maintenance or generating unnecessary warning messages. This can result in excessive brake pad wear, damage to the brake discs and compromised braking performance.
• Replacing the brake pad wear sensor whenever new brake pads are installed restores accurate brake wear monitoring and reliable warning system operation. The OE Match Front Brake Pad Wear Sensor is manufactured to OE standards using premium-quality materials, providing factory-style fitment, dependable performance and long-lasting durability, helping maintain the safety, reliability and braking performance expected from your Porsche.

Rear Brake Pad Wear Sensor 

Maintain the safety and performance of your Porsche braking system with this OE Match Rear Brake Pad Wear Sensor, designed specifically for the Porsche 957 Cayenne Turbo. Manufactured to original equipment specifications, this high-quality replacement brake wear sensor accurately monitors rear brake pad wear and alerts the driver when the pads have reached their service limit.


Fits:

• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10       

Designed as a direct replacement for the factory sensor, it provides reliable operation, precise fitment and dependable brake wear monitoring, helping to ensure your Porsche continues to deliver the braking performance expected from a high-performance SUV.

What Does the Rear Brake Pad Wear Sensor Do?

The rear brake pad wear sensor, also known as a brake pad warning wire, is fitted to the brake pad and monitors the thickness of the friction material throughout its service life.

Its primary functions include:

• Monitoring rear brake pad wear.
• Activating the dashboard brake wear warning light when replacement is required.
• Helping prevent excessive brake pad wear.
• Protecting expensive brake discs from damage.
• Supporting routine brake maintenance.
• Helping maintain safe braking performance.

This simple but essential component allows brake pads to be replaced before they become dangerously worn.

Why Do Brake Pad Wear Sensors Fail?

Brake wear sensors are exposed to constant heat, moisture, dirt and vibration. Common causes of failure include:

• Normal activation once the brake pads reach their wear limit.
• Damage during brake pad replacement.
• Heat deterioration from repeated braking.
• Corrosion affecting the sensor wiring or connectors.
• Impact damage from road debris.
• Age-related deterioration of the cable insulation.

Once activated, most Porsche brake wear sensors cannot be reused and should always be replaced when new brake pads are fitted.

When Should the Rear Brake Pad Wear Sensor Be Replaced?

The brake pad wear sensor should be replaced whenever:

• New rear brake pads are installed.
• The dashboard brake wear warning light is illuminated.
• The sensor has been damaged during servicing.
• The wiring is cracked or deteriorated.
• The connector shows signs of corrosion.
• The sensor has been activated through normal brake pad wear.

Replacing the sensor during every brake service helps ensure the brake wear monitoring system continues to operate accurately and reliably.
