Information
Brake pad wear sensor, Rear.
The rear brake pad wear sensor detects the remaining thickness of the brake pad friction material and signals the vehicle’s service reminder system when the pads need replacement. It helps drivers schedule brake service before pads reach critically low levels.
Sold each, 2 required per car
Fits:
Porsche 9YA Cayenne / Cayenne Coupe - 2018 to 2023
* For cars with option codes:
1KX - Rear disc brakes - disc diameter 18 inches, Brake calliper painted Silver
1KS - Rear disc brakes, 18", green
1KU - Rear brake discs, Disc diameter 19", Black brake callipers,
2EN - Rear brake discs, disc diameter 19-inches, Brake callipers, Red
2EI - Rear brake discs, disc diameter 18 inches, brake calliper painted Black
This OE Match rear brake pad wear sensor is engineered to meet OE-equivalent standards for electrical resistance, connector fit, and mounting geometry. It functions as a simple yet critical safety sensor: when the brake pad friction material wears down to the sensor level, it completes (or breaks) an electrical circuit that triggers a warning in the dashboard display.
Brake pad wear sensors protect your vehicle by providing an early notice that pad material has reached a minimum safe thickness. Without a functioning sensor, pads may wear excessively before being noticed - possibly leading to rotor damage, reduced braking performance, and higher repair costs.
This OE Match sensor installs directly into the brake caliper/lining assembly at the rear axle, using the original connection harness and clips. It’s ideal for brake servicing, pad replacement intervals, or when upgrading to OE-equivalent replacement pads.
Brake pad wear sensors are a key safety component: they help prevent unexpected brake failure, excessive rotor wear, and costly repairs by giving you an early warning that pads need service. Replacing a worn or broken sensor with an OE Match brake pad wear sensor ensures the vehicle’s warning system functions correctly and helps maintain proper brake maintenance intervals.
When to replace:
• Brake wear warning illuminates on the dashboard
• After replacing rear brake pads
• Sensor is damaged or corrosion present
• During brake system overhaul or service
• If the connector or wiring shows wear or damage

These OE direct-fit brake wear sensor integrates seamlessly with your Porsche's electronic braking system, ensuring accurate wear monitoring and helping prevent unnecessary brake disc damage caused by excessively worn brake pads.
What Does the Brake Pad Wear Sensor Do?
The brake pad wear sensor is an important safety component that monitors the thickness of the front brake pads. As the friction material wears down, the sensor eventually contacts the brake disc, completing an electrical circuit that activates the brake wear warning light on the dashboard.
Its primary functions include:
- Monitoring front brake pad wear.
- Activating the dashboard brake warning light.
- Preventing excessive brake pad wear.
- Helping protect the brake discs from damage.
- Supporting scheduled brake maintenance.
- Improving overall braking safety.
The sensor provides an early warning, allowing brake pads to be replaced before braking performance is compromised.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are consumable components and are
designed to be replaced during brake servicing. Common reasons for failure
include:
- Normal activation once the brake pads reach their wear limit.
- Heat generated by the braking system.
- Damage during brake pad removal.
- Road debris and moisture.
- Corrosion of the electrical contacts.
- Wiring damage caused by age or movement.
- General wear after years of service.
Once activated, the sensor cannot normally be reused and should always be replaced with new brake pads.
When Should the Brake Pad Wear Sensor Be Replaced?
Replacement is recommended whenever:
- The brake wear warning light is illuminated.
- New front brake pads are installed.
- The sensor has contacted the brake disc.
- The wiring has become damaged.
- Corrosion affects the electrical connector.
- During routine brake servicing.
- As part of a complete front brake overhaul.
Replacing the sensor at the same time as the brake pads ensures accurate future wear monitoring and avoids unnecessary labour costs.
